Trash Detection Algorithm Suitable for Mobile Robots Using Improved YOLO

The illegal dumping of aluminum and plastic into cities and marine areas leads to negative impacts on the ecosystem and contributes to increased environmental pollution. Although volunteer trash pickup activities have increased in recent years, they require significant effort, time, and money. Therefore, we propose automated trash pickup robot, which incorporates autonomous movement and trash pickup arms. Although these functions have been actively developed, relatively little research has focused on trash detection. As such, we have developed a trash detection function by using deep learning models to improve the accuracy. First, we created a new trash dataset that classifies four types of trash with high illegal dumping volumes (cans, plastic bottles, cardboard, and cigarette butts). Next, we developed a new you only look once (YOLO)-based model with low parameters and computations. We trained the model on a created dataset and a dataset consisting of marine trash created during previous research. In consequence, the proposed models achieve the same detection accuracy as the existing models on both datasets, with fewer parameters and computations. Furthermore, the proposed models accelerate the edge device’s frame rate.

Assessing the Human Health Risk from Heavy MetalContaminated Vegetables Grown Close to the Tannery Industrial Area Using the Hazard Index (HI) and Hazard Quotient (HQ)

To assess the contamination load in vegetables and its possible human health hazards, heavy metals concentration (Cr, Cd, Cu, Pb, Ni, and Zn) in vegetables grown in the vicinity of the studied tannery area were determined. Health risk due to the consumption of vegetables was calculated from the metal concentration of the studied vegetables and the study signifies more potential to cause health hazard (cancer) (Hazard Index>1). The present study indicated that concentrations of Cr in the vegetable species were within the range of 7.5-9.75, 5.38-10.14, 25.5-28.5 and 2.65 mg kg-1 of dry weight (DW), in bottle gourd fruit, bottle gourd shoot, kalmi shoot, and red amaranth, which was above the MPL (1-2 mg/kg). The findings revealed that the mean concentration of the studied heavy metals (Cr, Cd, Pb, Ni, Cu, Zn,) exceeded the MPL in most of the measured vegetables because of higher translocation from the source to edible parts. For the majority of the samples, the ADI values of Cr and Pb were higher than the PMTDI. Open dumping of tannery wastes and effluents, and tanning activities involve serious environmental hazards. Adequate preventive measures should be taken in tannery industrial activities with a view to ensuring a safe, sound, and healthy environment for the greater benefit of Bangladesh.

Can tourism support resource circularity in small islands? On-field analysis and intervention proposals in Madagascar.

Open dumping and burning of solid waste are common practices in low-income countries. On small and touristic islands, the problem is exacerbated due to the additional volume of waste amount generated by tourists. This article presents how, using Nosy Be island in Madagascar as a case study, waste recovery and recycling can be fostered by tourism to tackle the waste challenge. About 95% of the waste of Nosy Be is openly dumped, discarded to sea or openly burned. Field analysis, interviews with local stakeholders and waste flow analysis served as methodological tools to assess the current solid waste management (SWM) system of Nosy Be. Stakeholder mapping and involvement as well as first exchange among local and international actors provided the basis to identify key practice and opportunities. Research findings highlight the importance of active participation and involvement of local partners supported by international experts, to suggest how touristic centres can serve as core of circular approaches. The article presents potential circular models to be implemented in Nosy Be, taking tourism as the entry point including the aspects of financial support, separated waste flows and the interest in 'green tourism marketing'. This case study underlines how international cooperation, touristic activities and common efforts can potentially help low-income communities improve their SWM practices.

An ensemble machine learning model to uncover potential sites of hazardous waste illegal dumping based on limited supervision experience

With the soaring generation of hazardous waste (HW) during industrialization and urbanization, HW illegal dumping continues to be an intractable global issue. Particularly in developing regions with lax regulations, it has become a major source of soil and groundwater contamination. One dominant challenge for HW illegal dumping supervision is the invisibility of dumping sites, which makes HW illegal dumping difficult to be found, thereby causing a long-term adverse impact on the environment. How to utilize the limited historic supervision records to screen the potential dumping sites in the whole region is a key challenge to be addressed. In this study, a novel machine learning model based on the positive-unlabeled (PU) learning algorithm was proposed to resolve this problem through the ensemble method which could iteratively mine the features of limited historic cases. Validation of the random forest-based PU model showed that the predicted top 30% of high-risk areas could cover 68.1% of newly reported cases in the studied region, indicating the reliability of the model prediction. This novel framework will also be promising in other environmental management scenarios to deal with numerous unknown samples based on limited prior experience.

Identifying the Initiatives of Construction Waste Management in Malaysia towards achieving Sustainable Construction

Construction waste management is not a new topic in the construction industry. It involves the management of waste material arising from construction, renovation, and demolition activities as such concrete, timber, steel, and plastics products. The poor construction waste management practice has led to failure to ensure sustainability in construction by increasing environmental impacts and illegal dumping. Hence, with proper construction waste management techniques and processes, the notion of sustainable construction can easily be achieved. The aim of this study is to identify the initiatives for construction waste management toward sustainable construction. The study adopted a quantitative method of questionnaires survey distributed to 118 numbers of Grade 7 Contractors in Pahang. The professional teams in the company provide their responses in regard to waste management initiatives taken by them. The findings revealed several initiatives taken by contractors in helping to move towards sustainable construction in Pahang as such strengthening the policies in government agencies regarding waste management and compliance with the law to the general legislative structure. This study contributes to increasing the effectiveness of managing construction waste, particularly for contractor companies who are major involved during the construction process.

Significant impact on the growth of Solanum lycopersicum in Microbially augmented organic waste

The objectives of this study were to convert organic and tea waste to organic soil cond conditioners and achieve a 68% reduction in landfilling and illegal dumping of organic waste. The tea was mixed at an incremental ratio of 10% with the organic waste, and the groups were designated as T0-T100 groups, indicating 0% of tea waste and 100% of organic waste in T0 group and 100% of tea waste, and 0% of organic waste in T100 group. The impact of this soil conditioner was later studied on the growth of the Solanum lycopersicum (tomato) plant for twenty-one weeks along with the augmentation of waste sludge from the yeast manufacturing unit. Microbial examination, and other physicochemical parameters like pH, temperature, organic carbon, C/N ratio, moisture, cation exchange capacity (CEC), and humidity of the compost were studied. A visual color change indicated the compost maturity for further application. The quality of the soil was analyzed in both pre-compost and post-compost applications. The electrical conductivity of the soil was 3.0 mho with 8.3 pH, 0.84 % organic matter, phosphorous 1.0 mg/kg, and potassium 225 mg/kg with a saturation level of 40%. There was an inverse relation between organic waste and organic matter with the highest percentage of organic matter in the T0 group. Maximum nitrogen content (9.07%), the highest levels of phosphorous (0.7%), and potassium (2.3%) were recorded in the aerobic T0 group. The highest amount of organic carbon (78.23%), maximum CEC (109.09 meq/100g) was found in the aerobic T100 group. The best vegetative post-application growth of tomato plants, flowering, and fruiting was observed in the T60 group. Taken together with our findings, it can be concluded that the organic compost boosted the soil fertility by up to 70% which positively affected the growth of tomato plants.

Environmental and Health Consequences of E-Waste Dumping and Recycling Carried out by Selected Countries in Asia and Latin America

The volume of e-waste generated worldwide is surging, and it is set to escalate further due to continuing technological innovation and the early obsolescence of most electrical and electronic equipment (EEE). Even though there are many studies on e-waste management, the environmental and health consequences of e-waste regarding direct exposure during informal recycling and indirect exposure through environmental contamination are poorly studied. This study analyses the environmental and health consequences of e-waste dumping and informal recycling practices in selected countries such as Brazil, China, India, Mexico, and Pakistan. Several databases, such as Science Direct, ProQuest, Web of Science, and Emerald, were used to analyse studies from 2005 to 2022. Based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) protocol, 179 journal articles were evaluated. This study found that the majority of e-waste is poorly managed in terms of ecological safety and soundness. This study also found that illegal dumping, acid leaching, and open burning, which are practices that harm the environment and the well-being of e-waste workers, are still being performed by the selected countries. This study provides several practical suggestions for addressing the environmental and health consequences of e-waste dumping and recycling.

Sustainable Management of Bio Medical Waste in Chennai: A case study

The aim of the current research article is to study various treatment techniques involved in the management of bio medical waste and select the most appropriate treatment method in terms of cost savings, energy recovery and waste volume reduction in a sustainable manner. Most of the HCF (Health Care Facilities) lacks the provision for on-site waste treatment facility. One of the major reasons might be the fear of high pollutant emission levels from multiple machines or equipment used in the treatment process. At times, it could be due to lack of sufficient space within the clinical premises. To overcome this situation, a minor amendment has to be introduced in the bio medical waste management rules 2016, which includes providing a suitable area necessary for medical waste treatment within the premises, during the construction stage itself. Further, the identification of appropriate treatment techniques based on the type of waste generated is also important. Even a primary HCF too should be equipped with the requisite treatment facilities, considering the emission levels to be within the standards. This sort of installing an on-site waste treatment facility will reduce the amount spent upon external agencies for disposal and treatment of the medical waste. Then, the leftover residue is securely landfilled in the dedicated site or even be liable to mix with the municipal solid garbage. The current study concludes that the implementation of one of the treatment techniques in a specific hospital helps in energy recovery, huge reduction in the volume of waste generation and avoids illegal dumping of the waste, thereby creating less impact on the surrounding environment.

Consideration of hotspots in the selection of supervision schemes to reduce illegal dumping of construction and demolition waste.

Illegal dumping of construction and demolition waste continues to be a problem hindering circular economy efforts. Controlling illegal dumping necessitates establishing an effective surveillance scheme and investigating the proper penalty value. This problem has previously been described as a game theory problem, with the government and construction contractors as the players. Taking into account illegal dumping hotspots, which can often be identified through topographical and geographical characteristics, is also important when establishing supervision strategies. This study develops an evolutionary game-theoretic model that can assist in devising effective supervision strategies to control the spread of illegal dumping, while taking into consideration hotspots. In specific, this study investigates the suitability of two alternative strategies: police patrols and hybrid monitoring through both patrols and the installation of closed-circuit television cameras in hotspots. The model was applied to two case studies, using parameters informed by real-world contexts, to demonstrate its potential for selecting suitable strategies according to local situations. The results suggest that nine possible scenarios govern the stable evolutionary strategies of game players, with five scenarios in which contractors converge to adopt legal dumping. Accordingly, based on the parameters of the region (hotspot areas, cost of supervision, efficiency of patrols, penalties, etc.), governments would be able to assess which of the strategies would lead to long-term compliance of contractors while also increasing their payoffs. Further analysis allowed to determine the minimum efficiency required, and simulations were performed to demonstrate the influence of different supervision efficiencies and penalties on the evolutionary strategies.

Toxic Legacies and Health Inequalities of the Anthropocene: Perspectives from the Margins

Based on research in Matamoros (Mexico) and Naples (Italy), this article critically deconstructs embodiments and social histories of toxicity, addressing uneven power relations and health inequalities generated through late capitalism of the Anthropocene. By focusing on food and water consumption in regions at the margins of borders and defined as toxic wastelands, it sheds light on the multidimensional power structures of the global economy. Whether through reference to the illegal dumping of toxic waste by mafia-structured organised crime groups, or the contamination caused by foreign-owned assembly plants, the article illustrates how mechanisms taking place in the individual realm are ‘subsumed’ (Breihl 2019, 33) within more complex historical, economic, and environmental processes. These two case studies are the point of departure to reflect upon the undisclosed but powerful impact that commercial determinants of health have on individuals’ wellbeing, feeding profound north–south inequalities.

Экологические проблемы и особенности эколого-экономического развития Ненецкого автономного округа

The current stage of economic development of the Russian Arctic combines two contradicting tendencies — the intensification of economic development in line with the adopted special preferential measures and the aggravation of technical and technological contradictions under the tightening of sanctions and technological blockade, increasing wear of equipment, the loss of markets for extracted products. Under these conditions, anthropogenic and, particularly, technogenic environmental threats to nature and human habitat become the most important risk factor. The purpose of the work is to identify current eco-logical threats, problems and features of the environmental and economic development of the Nenets Autonomous Okrug. The study applies a comprehensive economic and sociological toolkit, including general theoretical approaches — dialectical, spatial economics and sustainable development, and private methods — statistical analysis, a number of sociological methods of collecting and processing data. The information basis of the study is the data of official authorities, statistics, the work of domestic and foreign scientists, as well as the results of a sociological survey of residents of the Nenets Autonomous Okrug (May 2022; n=539). Key features of environmental and economic processes in the region were identified. Low degree of waste processing, high risks of technogenic accidents at oil and gas production enterprises and transport infrastructure remain. The main environmental threats perceived by the population include oil and gas production facilities, household waste and illegal dumps. In a number of territories, threats from defense activities, catching and processing of fish and illegal fishing are also relevant. The population is least satisfied with the quality of water resources, the cleanness of the environment and the state of forests and parks. Based on the results obtained, recommendations aimed at optimizing the environmental component of the social well-being of the population are given. The scientific significance of the study is determined by the actualization of knowledge about environmental and economic processes in the Arctic region of the Nenets Autonomous Okrug, based on a comprehensive economic and sociological toolkit. The practical importance lies in the formation of the analytical framework for managing the environmental and economic development of the regions during the period of exacerbated contradictions in the development of the Russian Arctic.

Polystyrene nanoplastics in the marine mussel Mytilus galloprovincialis.

Concerns about plastic pollution and its toxicity towards animals and people are growing. Polystyrene (PS) is a plastic polymer highly produced in Europe for packaging purposes and building insulation amongst others. Whatever their source—illegal dumping, improper waste management, or a lack of treatment for the removal of plastic debris from wastewater treatment plants—PS products ultimately end up in the marine environment. Nanoplastics (<1000 nm) are the new focus for plastic pollution, gaining broad interest. Whether primary or secondary, their small size permits nanoparticles to cross cellular boundaries, consequently leading to adverse toxic effects. An in vitro assay of Mytilus galloprovincialis haemocytes exposed to 10 μg/L of polystyrene nanoplastics (PS-NPs; 50 nm) for 24 h was used to test cellular viability along with the luminescence inhibition (LC50) of Aliivibrio fischeri bacteria to evaluate acute toxicity. Cellular viability of mussel haemocytes decreased significantly after a 24 h exposure and PS-NPs LC50 range from 180 to 217, μg/L. In addition, a 28-day exposure of the marine bivalve M. galloprovincialis to PS-NPs (10 μg/L; 50 nm) was performed to evaluate the neurotoxic effects and the uptake of these plastic particles in three bivalve tissues (gills, digestive gland, and gonads). The ingestion of PS-NPs was time- and tissue-specific, suggesting that PS-NPs are ingested through the gills and then translocated through the mussel bloodstream, to the digestive gland and gonads where the highest amount of ingested PS-NPs was reported. Ingested PS-NPs may compromise the digestive glands' key metabolic function and impair mussels' gametogenic and reproductive success. Data on acetylcholinesterase inhibition and those previously obtained on a wide range of cellular biomarkers were elaborated through weighted criteria providing a synthetic assessment of cellular hazard from PS-NPs.

Selection of Ideal MSW Incineration and Utilization Technology Routes Using MCDA for Different Waste Utilization Scenarios and Variable Conditions

Liability to prevent the consequences of an unhealthy situation due to accumulating toxic and hazardous emissions caused by open dumping of municipal solid waste with increasing urbanization has necessitated a renewed thinking on waste disposal. Grate-fired incineration systems were adopted by urban management in the past and present, but with criticism due to the formation of airborne emissions. Improved combustion methods like fluidized beds are now propagated because of current requirements like efficient energy recovery potential, stricter emission norms, adaptability with urban growth, adaptability to co-firing with other waste like biomass, edible oil wastes or industrial effluent, and integration with conventional energy generation. Such a comprehensive and futuristic approach is more sustainable for the community. A multi-criteria decision-making tool is used to identify the best technology option between grate combustion and fluidized bed combustion for disposing and energy recovery from waste. A total of 10 different collection and disposal options involving two combustion methods, namely, grate combustion and fluidized bed method, are considered. Utilization of the energy is done for three end uses, namely, power generation, water distillation, and district cooling. Two different regions in an arid climate zone are considered for this study under two types of scenarios, namely with recycling and without recycling. The different options are prioritized based on their overall ranking using five major performance factors.

Pemberdayaan Ekonomi Masyarakat Melalui the Gade Clean and Gold Dalam Perspektif Islam

The bad habit of the people who often dispose of waste indiscriminately and waste management with the concept of open dumping, burning it (with an incinerator or just burning it), digging the lid (sanitary landfill) do not provide a good solution. To overcome the problem of waste, it is necessary to change the paradigm that views waste as a resource that has economic value and is utilized. This research is included in qualitative research and uses qualitative descriptive methods. The techniques used in collecting data are observation, interviews and documentation. The key informants in this study were the Head of the Carnation Garbage Bank, the manager of the Carnation Garbage Bank and the customers of the Carnation Garbage Bank. The results of the empowerment carried out by the Anyelir Garbage Bank are that people who become customers of the waste bank get benefits in the form of gold savings, and the community has the ability to process waste and knowledge about maggot caterpillar cultivation. . The supporting factors are the involvement of members, facilities and infrastructure, the involvement of the surrounding community and collaboration with other parties and the inhibiting factors are the currently available facilities, customer indiscipline, and the low mindset of the community. The community empowerment process through activities at the Anyelir Garbage Bank with The Gade Clean and Gold Program went well and received good appreciation.

Mini-review on remediation of plastic pollution through photoreforming: progress, possibilities, and challenges.

The increasing plastic pollution has raised significant concerns about the environment and the destruction of its precious resources. Making value-added products out of plastic waste is an effective way to reduce plastic pollution and use it as a valuable resource. Plastic reforming driven by sunlight offers a quick and low-energy way to produce hydrogen from waste. Photoreforming of plastic waste is an emerging technology that cannot only break down plastic polymer waste into value-added chemicals but also produce solar fuel cell quality H2. Technologies, such as pyrolysis, combustion, and advanced oxidation, are right now being studied for converting plastic pollution into energy. A thorough summary and comparison of different technologies have not yet been published. Open dumping and combustion are two main steps to deal with waste plastics, but these processes experience inefficiencies and cannot adequately address the challenges. In this mini-review, we aimed to provide a short overview of the recently reported conventional and novel plastic waste treatment methods. The current research on the photoreforming of plastics conducted by various groups and some advantages and disadvantages of this practice has been discussed thoroughly. Also, some notes were made on the prospective future scope present in this particular research area to achieve a carbon-free fuel system. The purpose of this review is to encourage the utilisation of plastic garbage as an alternative source of energy.

Assessment of road run-off and domestic wastewater contribution to microplastic pollution in a densely populated area (Flanders, Belgium)

Plastics are omnipresent in our daily life. Unfortunately, the produced plastics will partly end up in the environment including aquatic ecosystems. People often refer to littering or illegal waste dumping as sources of plastic emission to the environment. However, daily-life sources could also, unknowingly, contribute considerably to the total microplastic pollution in the ecosystem. Hence, there is an urgent need to study these potential sources. In this research, two common sources, i.e. domestic wastewater and road run-off from tire and road wear particles, were studied in detail to quantify the relative contribution of both domestic sources towards microplastic pollution in freshwater ecosystems in Flanders, Belgium.This assessment shows that every person (in studied area) emits on average 1145 microplastics (25–1000 μm) daily through domestic wastewater, resulting in a yearly discharge of 418,000 microplastic particles per person. The road run-off samples contained between 0.02 and 9.2 mg tire wear particles per litre per day, which corresponds to an emission of 10.8 mg tire wear particles per driven vehicle km.The gross and net emissions of both above mentioned microplastic sources were extrapolated to the whole Flanders region using an emission model. From the yearly gross microplastic pollution in the domestic wastewater, 623 kg (20%) will be discharged in the freshwater. The highest losses originated from the households that have a private drain or are not (yet) connected to an active wastewater treatment plant. In Flanders, the yearly net microplastic emission into the aquatic environment of tire wear particles is estimated to be 246 tonnes (38%), mainly from the direct run-off from the road surface. Based on the results, specific mitigation measures can be installed to reduce the emission of microplastics towards the freshwater ecosystem. Other sources should be quantified in a similar way for a more holistic strategy to counteract plastic pollution.

Contamination, ecological and health risk assessments of potentially toxic elements in soil around a municipal solid waste disposal facility in Southwestern Nigeria

BackgroundThe increasing level of waste generated and disposed of especially in urban centers arising from population explosion and rapid industrialization is a global concern, because it may lead to the pollution of potentially toxic element (PTE) in surrounding soils and groundwater. This research is aimed at the investigation of PTE contamination in soil around a municipal solid waste open dump facility and their human health risk in Ibadan, Southwestern Nigeria. MethodsForty (40) soil samples were collected at 20 cm depth within the facility (WFC), close to the facility (CFC), and far from the facility (FFC). The soil samples were analysed for Cd, Co, Cu, Mn, Ni, Pb, and Zn using atomic absorption spectrometry technique. ResultsOn the basis of the mean concentration, PTEs decrease in the following order Zn > Mn > Pb > Cu > Co > Ni > Cd. The contamination statuses of Cd, Cu, Pb and Zn were high-very high at WFC, moderate-high at CFC, and low-moderate at FFC. The principal component (PC) analysis showed three loadings; PC1 composed of Cd, Cu, Pb, and Zn that were attributed to anthropogenic input from the materials dumped within facility while PC2 (Co and Ni) and PC3 (Mn) were sourced from the geogenic origin from weathering of rocks and soils. Only the ecological risk potential (Er) of Cd and Pb was high at WFC, considerable at CFC and low at FFC and affect the overall ecological risk (RI) of WFC and CFC. The hazard quotient and hazard index of non-carcinogenic risk were only > 1 for Cd especially for children at WFC and therefore, may pose health risk in the vicinity of the facility. The carcinogenic risk (CR) is within permissible limit. ConclusionThe anthropogenic activities in the municipal solid waste facility have impacted the soil of the area by some PTEs and posed potential human health risk to the people living close to the site. Therefore, constant monitoring of the area by regulatory bodies is recommended to reduce the impact of the PTEs on the soil.

Solid Waste Audit and Characterization Study at Tuensang Town Nagaland

Today scenario improper waste management causes serious pollution and health risk, which is the main concerning environmental management in developing countries. In most cities, the use of open dumps is common for the disposal of wastes, resulting in soil and water resource contamination. The study carried from March to May 2023.A Total of 30 households were studied for data collection (210 samples) from three types of family, low income, medium income and high income family using the random sample, out of 15 wards,8 wards were used for the sample selection. The study shows that the majority of the residents are very much concerned about the poor condition of the environment due to the inappropriate and improper SWM in Tuensang town. The residents are not much satisfied with the service of the town council in regard with SWM dumping in the hearts of Tuensang. There is no scientific engineered solid waste disposal site in the Tuensang town and the results can be a starting point in planning for such. This paper give the total waste generation in the household level, weekly and yearly per capita per day and and also give the types of solid waste generation in the town. Based on the findings of the study, researcher proposes that district and town needs to provide proper solid waste segregation awareness to the general citizen to every household. It may also encouraged citizens not to dispose of their household wastes randomly.

Qualitative and Quantitative Recognition of Volatile Organic Compounds in Their Liquid Phase Based on Terahertz Microfluidic EIT Meta-Sensors

Volatile organic compounds (VOCs) are directly associated with human health concerns and environment safety. Therefore, it is urgent to achieve an accurate detection of VOCs both qualitatively and quantitatively. In this work, the qualitative detection of ethyl benzene (EB), isopropyl alcohol (IPA), ethyl acetate (EA) – three pure VOCs in liquid phase were discussed using terahertz (THz) microfluidic Electromagnetic Induced Transparency (EIT) meta-sensor. The THz response illustrated that with an increase in VOCs’ volumes (1~6μL), resonant frequencies of dual transmission dips (0.855, 1.724 THz) and the EIT peak (1.213THz) exhibited red shift. The limit of detections for pure IPA, EA, EB can achieve 5.45μg, 13.46μg, 4.35μg, respectively. The multivariate fusion (MF) model based on the EIT responses to VOCs was utilized to improve the accuracy of trace detection and classification of VOCs. Furthermore, the above method combined with principal component analysis with Gaussian mixture model (PCA-GMM) and the neural network classification algorithm support vector machine (SVM) was applied to the recognition of VOCs. In addition, the THz method is not feasible to detect trace amounts of VOCs (typically 0.3mg/L) in waste water because water is highly absorbable in THz band and VOCs will evaporate if water is removed. Here, IPA, EA, EB in soil were detected and classified by PCA-GMM combined with MF. Our results provide a new terahertz meta-sensor platform to trace detection of VOCs in liquid phase and in soil and may be used to identify hazardous wastes in illegal dumping.
