ЗЕЛЕНІ ТЕХНОЛОГІЇ В МАЛОМУ БІЗНЕСІ: РОЗВИТОК І ПЕРСПЕКТИВИ ВПРОВАДЖЕННЯ

The article considers the prospects of green technologies, the state and factors hindering their further development in Ukraine. Proposals for the development of green technologies in Ukraine for expanding the participation of small businesses in this process are provided. It has been established that the transition from the traditional model of economic growth to the model of green growth, which provides a high level of production and employment, as well as a fair distribution of income without harming the environment, contributes to sustainable economic development. Based on expert estimates, it is proven that green technologies will become leading in the XXI century. As a result, a small business belonging to a mobile institution can effectively implement green technologies, thus solving a wide range of problems related to its development. It is known that Ukraine is one of the ten countries in the world that produce the largest amount of solid waste. Much of the solid waste from households is dumped in landfills and cannot be recycled and reused due to the complexity of their separate collection, which exacerbates the problem. Small businesses are involved in the process of efficient recycling of solid waste, starting from the stage of preparation for recycling and ending with the process of their disposal. The experience of waste recycling in a closed-cycle economy as part of Industry 4.0, which is characterized by minimizing the negative impact on the environment, is considered. Issues related to solid waste management are considered. Difficulties in the processing of secondary raw materials were highlighted, including the shortage of secondary raw materials in the country and the need to import them, as well as the lack of waste sorting and the necessary containers for the collection of separated waste. The conditions for encouraging the sorting of household waste from the standpoint of environmental and economic feasibility are presented. Measures have been proposed to introduce closed-loop green technologies in Ukraine and involve small businesses (especially in the management of solid and organic household waste), including: bringing legislation in line with the requirements of the closed-loop economy (separate collection of household waste); conducting organizational and educational activities in society to organize separate collection of household waste; ensuring the production of technical means for their separate assembly.

Patent Landscape of Composting Technology: A Review

Organic waste management is a major global challenge. It accounts for a significant portion of waste that ends up in landfills, where it gradually decomposes and emits methane, a harmful greenhouse gas. Composting is an effective method for potentially solving the problem by converting organic waste into valuable compost. Despite many studies focusing on the composting process, no study has reviewed the technological advancements in the composting fields from the perspective of patents. This review paper begins with background information on the composting process, specifically important factors affecting the process, problems associated with it, and the available technologies to facilitate the process. Different technologies are discussed, ranging from manual to automated methods. Subsequently, 457 patents are selected, classified into different categories, and reviewed in detail, providing a patent technology landscape of composting technology. Automatic composters are more prominent than manual ones as managing organic waste at the source has become more crucial in recent years. The need for a domestic composter creates an opportunity for the development of a compact and automated system for organic waste management, which is more suitable for urbanized settings. This technology has the potential to reduce the amount of organic waste that needs to be managed at an already overburdened landfill, as well as the environmental consequences associated with it.

This study promising that millicomposting is an ecofriendly method to solve the acute problem of solid waste.

Qualitative Aspects of Biogas Production in a Small-Scale Biodigester by Anaerobic Digestion of Food Waste from University Environment

Organic waste are materials that, in balanced natural environments, spontaneously degrade and recycle nutrients in nature's processes. The adoption of appropriate methods for the management of organic waste is essential for urban, peri-urban and rural development. The use of Small-scale biodigestion systems in urban areas and mainly in rural areas is a real alternative. Biogas is a renewable source of energy used as a substitute for natural gas and liquefied petroleum gas. From the anaerobic decomposition of different types of biomass and substrates, we have the metabolic product called biogas, a mixture of methane, carbon dioxide and small amounts of other gases such as hydrogen sulfide. The quality of the biogas generated has a direct effect on its use as an energy source, requiring a minimum fraction of CH4 for its combustion and for other processes such as the transformation of the biogas generated into biofuel, its purification to remove the portions of other gases present its necessary. This work evaluated the quality of the biogas generated in a small-scale biodigester, based on the decomposition of food waste from the university environment. A mobile laboratory analyzed the composition of the biogas generated. The results showed that this substrate and its heterogeneity has enormous potential for generating biogas with excellent amounts of methane CH4 composition minimum value was 58.46%, the maximum reached 68.41% and the average was 65.44%. Regarding the presence of CO2 within the biogas evaluated, the minimum value of CO2 was 38.02%; the maximum value was 44.39% and the average stayed in 38.55%. Hydrogen in the composition minimum value was 7.41 ppm, 13.42 ppm maximum and average of 9.63 ppm. H2S minimum value obtained was 0.0 ppm, reaching the maximum value of 249.76 ppm, with average of 138.75 ppm.

Empowerment of Farmer Group in Bioconversion of Organic Waste Management with Utilization of Black Soldier Fly Larvae Become Organic Fertilizer “Kasgot”

The amount of organic waste in the form of cow, poultry, goat manure, and fruit and vegetable waste that is no longer suitable for consumption has the opportunity to be reprocessed into a product that can be reused in Sidomulyo Village. The lack of awareness and knowledge of the farmer group community to process organic waste is one of the factors causing the accumulation of organic waste so that it becomes useless and can pollute the environment. In addition, organic waste processing can also be used as a way to promote zero waste in the village environment. One of the innovations that can be applied and utilized by farmers in processing organic waste and producing organic fertilizer with the best quality is bioconversion by utilizing maggot or larvae from BSF (Black Soilder Fly) flies which are able to decompose organic waste in a fairly short time because maggots are animals. greedy in consuming their feed (organic waste). The purpose of this activity is to assist farmers in processing organic waste. This activity resulted in product innovation in the form of cassava fertilizer which can be reused by farmers as organic fertilizer and can be used as animal feed.

Integrated Approach to Achieve a Sustainable Organic Waste Management System in Saudi Arabia.

Organic waste management (OWM) has always been a fundamental aspect of human populations. Approaches to OWM must be matched to the characteristics of a certain population. In this consideration, the Kingdom of Saudi Arabia (KSA) is no exception. Organizations are being aligned to focus on sustainability matters sharing significant features with universal trends, especially the integration of 3Rs (reducing waste, reusing, and recycling resources). However, the degree and nature of advancement in the direction of sustainability vary depending on the economic level of a state. High-income economies can afford to pay a higher price to integrate 3Rs technologies. Most recent endeavors have focused on achieving ‘Zero Waste’, which is costly for low-income developing countries. The expectations of OWM systems in KSA must be estimated. In this work, the situations in KSA and other countries are analyzed, and pertinent aspects are explored. Matters relating to the sustainability of OWM are conceptually assessed. This study proposes an integrated method for an organic waste management system to achieve sustainable OWM in the context of state policy and appropriate frameworks, suitable technology, institutional order, operational and monetary administration, and people consciousness and involvement. A genetic-based waste collection transportation algorithm that enhances the efficiency of waste collection truck management is presented in line with this technology. The selected routes based on the Rfs and IPv are the most efficient among those available for the examined smart bin destinations. The minimum Rfs of selected routes is less than the maximum Rfs of available routes by 2.63%. Also, the minimum IPv of selected routes is less than the maximum IPv of available routes by 27.08%. The proposed integrated approach, including the waste collection transportation algorithm, would be beneficial across a variety of country-specific layouts.

Information source utilization for organic waste management with special reference to digital technologies: A qualitative study on dairy farmers of district Ludhiana, Punjab

The current study was conducted to analyse the sources of information utilized by dairy farmers of rural Punjab for obtaining information on organic waste management. A total of 80 farmers (40 each, small and large) were selected for the study. Results revealed that small farmers had a low level of information source utilization whereas, large farmers had a medium level of utilization. Pooled data revealed that the utilization of information sources by farmers is of medium level, but ICT utilization was found to be the highest for obtaining information. The Mann-Whitney U value was found to be highly significant (p < 0.01) between groups. Furthermore, education, information source utilization and knowledge level were found to be having a highly significant and positive relationship with ICT usage. As in the present study, ICT utilization among farmers was high, therefore, more ICT tools should be developed for efficient organic waste management, which will not only hasten information dissemination but also strengthen extension delivery in rural areas.

Improvement of the anaerobic digestion of sewage sludge by co-digestion with wine vinasse and poultry manure: Effect of different hydraulic retention times

This study arose in response to the management of different organic wastes generated locally, which cause environmental damage. These wastes could be used to obtain biogas and class A biosolids through anaerobic digestion. For this purpose, the mesophilic anaerobic tri-digestion of sewage sludge (S), wine vinasse (V) and poultry manure (PM) (49.5:49.5:1) was studied to obtain biogas in an improved way compared to bi-digestion of SV (50:50) and mono-digestion of S. Tests were carried out in anaerobic digesters, at laboratory scale, to compare the benefits at different hydraulic retention time (HRT) (20, 15, 13, 10, 8 and 6 days). From the results obtained, anaerobic tri-digestion of the waste gave the best results, with a total chemical oxygen demand (TCOD) removal efficiency of 51%, volatile solids (VS) removal efficiency of 57%, and methane yield values of 261 mLCH4/gVSadded at a HRT of 13 days. In relation to the pathogens, both co-digestion studies addressed managed to inactivate enough pathogens in the effluent to be classified as class A biosolids. This would allow considering the anaerobic tri-digestion as a promising technology, which allows valorizing organic waste, obtaining biogas and class A biosolids, moving towards a circular bioeconomy.

Pengelolaan Limbah Industri Pengolahan Hasil Perikanan: Studi Kasus Pada Usaha Mikro Kecil dan Menengah (UMKM) Sambal Ikan Tuna Di Kabupaten Cilacap

One of the fisheries and marine potentials in Cilacap Regency is tuna fisheries. Catch tuna that landed at the Cilacap Ocean Fishery Port (PPSC) is high. Based on the analysis of the needs of actors in the tuna fisheries system in Cilacap, one of the components included in the system is the tuna fish processing industry. This is because there is only one tuna fishing company in Cilacap in 2009. The existence of these problems causes an increase in the growth of the micro-industry in the tuna fish processing business in Cilacap. This increase certainly has an impact on increasing the waste generated. This study aims to identify the type of waste generated and the waste management efforts of micro-industry players (MSMEs) processing tuna chili sauce in Cilacap and analyze the appropriate management design to be applied in the tuna fish sauce processing industry. The research data collection method was carried out by direct observation by conducting interviews with the owners of MSMEs. The results of field observations on MSMEs that produce tuna fish sauce produce organic and non-organic waste and the waste is simply thrown into the environment without any treatment first. Efforts to manage waste produced by MSMEs with tuna sauce have not yet been carried out due to limited human resources in knowledge about waste management. Based on the characteristics of the waste produced, several types of designs can be carried out by MSMEs, namely the management of organic and non-organic wastes to minimize the waste generated both in terms of quality and quantity as not to pollute the environment.

PEMANFAATAN LARVA LALAT BLACK SOLDIER FLY (Hermetia illucens) UNTUK PEMBUATAN PUPUK KOMPOS PADAT DAN PUPUK KOMPOS CAIR

Composting is a form of decomposing organic matter with the help of organisms for bioconversion. The composting process requires several requirements to produce good quality compost, namely water content, pH and nutrient availability which is reflected in the C / N ratio. One type of insect larvae that can be used as an element of organism is the Black Soldier Fly (BSF) insect. The effort to recycle organic waste involving Black Soldier Fly (BSF) insect larvae is a new paradigm in the management of organic waste as decomposers or decomposers of organic waste. The result of the conversion of organic waste into solid compost fertilizer has a moisture content value that exceeds quality standards, C-organic value and C / N ratio which is below the quality standard, has a basic pH, and macro nutrients (N + P2O5 + K2O) located in the Permentan quality standard No. 261 / KPTS / SR.30 / M /4/2019, while for liquid compost fertilizer the value of C-organic and macro nutrients (N + P2O5 + K2O) is in Permentan quality standard No.261 / KPTS / SR.30 / M / 4/2019.

Development of microbial consortium for degradation of organic kitchen waste

Increasing population and urbanization has led to an exponential increase in organic waste. This waste if not treated properly may lead to pollution and health hazards. So, a study was conducted to develop an efficient bacterial consortium for the degradation of organic kitchen waste. Different bacterial strains were obtained from MTCC, initially grown on specific media and were screened for their enzymatic activities. Eight bacterial strains viz. Bacillus subtilus (MTCC 441), B. amyloliquefaciens (MTCC 7913), B. megaterium (MTCC 8510), Lactobacillus delbrueckii (MTCC 2365), L. plantarum (MTCC 1407), L. rhamnosus (MTCC 1423), Pseudomonas aeruginosa (MTCC 4673) and Staphylococcus aureus (MTCC 740) were tested for the production of lipase, amylase, protease and cellulase. All the bacterial strains exhibited enzyme activities except B. megaterium. So, combinations of these strains were used to make consortia on basis of pathogenicity. Two different microbial consortiums were prepared with Consortia 1 comprising B. subtilis, L. plantarum, L. rhamnosus, L. delbrueckii, B. amyloliquefaciens and Consortia 2 comprising P. aeruginosa, S. aureus, L. delbrueckii, L. rhamnosus, B. subtilus. Consortium 1 displayed the highest amylase and protease activity as compared to Consortium 2, and therefore selected for monitoring the composting parameters of the organic kitchen wastes. The microbial consortium showed significant outcome for composting parameters such as moisture content (65 – 58 %), temperature (25 – 29 ºC), pH (5.5 – 5.7), organic carbon (41 – 36 %) and decrease in mass (25 %) from 25 to 35 d of composting organic kitchen waste. The C/N ratio was calculated at 38/1 which falls within the optimum composting period. Developing a microbial consortium significantly reduces the degradation time and thereby the composting process. This microbial consortium is environmentally safe and can therefore, be used to effectively improve the management of organic waste at both the community and industrial level.

“Environmentally-Friendly Movement” as a Program to Support Sustainable Development Goals Using Text Mining Methods

Nowadays, environmental initiatives and campaign activities are promoted massively in Bandung City. These activities are part of the program to achieve sustainable development goals at the municipal level. Text mining methods from online news and media were conducted to understand the implication of the program to the pro-environmental behavior and consciousness of the Bandung City residents. A questionnaire survey to 340 residents of Bandung City was also distributed randomly to see the relationship between sociodemographic profiles (age and education level) and pro-environmental behavior of the respondents. Results showed that the Kang Pisman program became the highest environmentally friendly movement program promoted through mass media. This result also correspondence to the questionnaire survey in which people in Bandung City try to reduce their produced waste. Besides, education level is insignificant, and age becomes one-factor influencing environmental behavior. The interesting point is that the government should enhance organic waste management since many people are unwilling to process their organic waste. To promote, educate, and engage residents in pro-environmental behavior, stakeholders should conduct environmentally friendly movements, thus achieving local SDGs target.

BIOLOGY OF THE EPIGEIC EARTHWORMS IN TROPICAL WET AND DRY CLIMATE OF DHARWAD (KARNATAKA), INDIA

Studies on biology of epigeic earthworms is very much necessary for the selection of suitable earthworm species in effective organic waste management through vermiculture and vermicomposting process for the production of quality and quantity worm biomass (vermiprotein) and vermicompost (biofertilizer). Hence, the present study was undertaken to study the biology of different epigeic earthworm species such as Eudrilus eugeniae (EE), Eisenia fetida (EF) and Perionyx excavatus (PE) cultured in cattle manure at tropical wet and dry climate of Dharwad district, Karnataka state, India. The results of the present study revealed that the incubation period or the time of emergence of juveniles from the cocoon was less (16.33±0.53 days) in Perionyx excavatus as compared to Eudrilus eugeniae (22.33±0.73 days) and Eisenia fetida (24.33±0.88 days). The percent hatching of cocoon was more in E. eugeniae (86.66±6.66) followed by E. fetida (73.33±5.33) and P. excavatus (66.66±4.66), whereas number of hatchling/cocoon was more in Eisenia fetida (2.66±0.33) followed by Eudrilus eugeniae (2.33±0.28) and less in Perionyx excavatus (1.33±0.23). The mean weight of juvenile (mg) at the time of hatching was more in EE (7.90±0.20) followed by EF (7.00±0.57) and less in PE (5.70±0.35). The attainment of sexual maturity was observed early during 6th -9th week in EF and PE, but it was late in EE during 7th -10th week and commencement of cocoon production was noticed soon after one or two week of maturity i.e. from 8th week onwards. It was continuous and multimodal in nature with slight decline in the growth rate after maturity and cocoon production in all three epigeic earthworm species (EE, EF and PE). The various life activities such as incubation period and number of hatchling, maturity were more in EF as that of EE and PE, whereas percent hatching and juvenile weight were more in EE followed by EF and PE. Therefore, the success of vermiculture and vermicomposting process for the production of quality and quantity worm biomass (vermiprotein) and vermicompost (biofertilizer) is mainly depends on the biology or life cycle of the epigeic earthworms, type of organic waste materials used and it also depends on the prevailing abiotic factors.

Recent Advances on Innovative Materials from Biowaste Recycling for the Removal of Environmental Estrogens from Water and Soil.

New technologies have been developed around the world to tackle current emergencies such as biowaste recycling, renewable energy production and reduction of environmental pollution. The thermochemical and biological conversions of waste biomass for bioenergy production release solid coproducts and byproducts, namely biochar (BC), hydrochar (HC) and digestate (DG), which can have important environmental and agricultural applications. Due to their physicochemical properties, these carbon-rich materials can behave as biosorbents of contaminants and be used for both wastewater treatment and soil remediation, representing a valid alternative to more expensive products and sophisticated strategies. The alkylphenols bisphenol A, octylphenol and nonylphenol possess estrogenic activity comparable to that of the human steroid hormones estrone, 17β-estradiol (and synthetic analog 17α-ethinyl estradiol) and estriol. Their ubiquitous presence in ecosystems poses a serious threat to wildlife and humans. Conventional wastewater treatment plants often fail to remove environmental estrogens (EEs). This review aims to focus attention on the urgent need to limit the presence of EEs in the environment through a modern and sustainable approach based on the use of recycled biowaste. Materials such as BC, HC and DG, the last being examined here for the first time as a biosorbent, appear appropriate for the removal of EEs both for their negligible cost and continuously improving performance and because their production contributes to solving other emergencies, such as virtuous management of organic waste, carbon sequestration, bioenergy production and implementation of the circular economy. Characterization of biosorbents, qualitative and quantitative aspects of the adsorption/desorption process and data modeling are examined.

Valorization of Hazardous Organic Solid Wastes towards Fuels and Chemicals via Fast (Catalytic) Pyrolysis

The management of municipal and industrial organic solid wastes has become one of the most critical environmental problems in modern societies. Nowadays, commonly used management techniques are incineration, composting, and landfilling, with the former one being the most common for hazardous organic wastes. An alternative eco-friendly method that offers a sustainable and economically viable solution for hazardous wastes management is fast pyrolysis, being one of the most important thermochemical processes in the petrochemical and biomass valorization industry. The objective of this work was to study the application of fast pyrolysis for the valorization of three types of wastes, i.e., petroleum-based sludges and sediments, residual paints left on used/scrap metal packaging, and creosote-treated wood waste, towards high-added-value fuels, chemicals, and (bio)char. Fast pyrolysis experiments were performed on a lab-scale fixed-bed reactor for the determination of product yields, i.e., pyrolysis (bio)oil, gases, and solids (char). In addition, the composition of (bio)oil was also determined by Py/GC-MS tests. The thermal pyrolysis oil from the petroleum sludge was only 15.8 wt.% due to the remarkably high content of ash (74 wt.%) of this type of waste, in contrast to the treated wood and the residual paints (also containing 30 wt.% inorganics), which provided 46.9 wt.% and 35 wt.% pyrolysis oil, respectively. The gaseous products ranged from ~7.9 wt.% (sludge) to 14.7 (wood) and 19.2 wt.% (paints), while the respective solids (ash, char, reaction coke) values were 75.1, 35, and 36.9 wt.%. The thermal (non-catalytic) pyrolysis of residual paint contained relatively high concentrations of short acrylic aliphatic ester (i.e., n-butyl methacrylate), being valuable monomers in the polymer industry. The use of an acidic zeolitic catalyst (ZSM-5) for the in situ upgrading of the pyrolysis vapors induced changes on the product yields (decreased oil due to cracking reactions and increased gases and char/coke), but mostly on the pyrolysis oil composition. The main effect of the ZSM-5 zeolite catalyst was that, for all three organic wastes, the catalytic pyrolysis oils were enriched in the value-added mono-aromatics (BTX), especially in the case of the treated wood waste and residual paints. The non-condensable gases were mostly consisting of CO, CO2, and different amounts of C1–C4 hydrocarbons, depending on initial feed and use or not of the catalyst that increased the production of ethylene and propylene.
