An elastoplastic constitutive model for municipal solid waste (MSW) incorporating solid particle compression and fibrous reinforcing effect

The failures in municipal solid waste (MSW) landfills could result in considerable ecological as well as social problems. Numerical simulations are widely employed to analyze MSW deformation and stability. These methods require an appropriate stress-strain characterization of MSW, which is crucial. Different from soils, the extremely complicated constituents of MSW contain a large number of fibrous reinforced and particle compressible materials. The findings of numerous tests suggest that the fiber reinforced phase and the basic phase are solely responsible for determining the mechanical properties of MSW. On the basis of the double-phase assumption, a new plastic potential function of MSW is developed considering that the reinforcement of fibrous materials only relates to plastic shear strain and the particle compression only affects plastic volumetric strain. According to the associate flow rule, a constitutive model based on elastoplasticity is developed for MSW. The strain hardening behaviour of MSW is well predicted by the model, and this behaviour is in good agreement with experimental evidence. Effects of confining pressure and fibre content are modelled, together with the mechanical and deformation behaviour of MSW. The accurate calculation of effective stresses is obtained through considering the MSW particle compression under the undrained conditions. Parametric investigations calibrate the model and show its properties by comparing them to data from triaxial tests. Moreover, incorporating the proposed model, finite-element numerical simulation was conducted, and the results of finite-element numerical simulation were compared with field monitoring results.

Synergistic interaction for catalytic co-pyrolysis of municipal paper and polyethylene terephthalate wastes coupling with deep learning methodology

Municipal papers and polyethylene terephthalate (PET) wastes are primary constituents of municipal solid waste (MSW) which necessitates effective disposal. Co-pyrolysis is an efficient transformation technology for the production of valuable gas and liquid fuels. Therefore, co-pyrolysis characteristics, kinetics, gas and liquid products of cellulose and PET mixtures were investigated in a two-stage reactor by multiple characterizations coupling with deep learning approach. The results indicated that there exhibited positive interaction for cellulose and PET co-pyrolysis in terms of mass difference (δm) and mass loss rate difference (δr) between experimental and calculated values. The thermal decomposition process and synergistic effects (δm and δr) were accurately predicted by deep learning approaches (R2 =0.9823–0.9993) using temperature, catalyst, mixing ratio and heating rate variables. Feature importance revealed that the temperature, catalyst, heating rate and mixing ratio were in the descending order to affect the remaining mass from TG curves. And the temperature played a predominant role in synergistic effects. The Flynn-Wall-Ozawa (FWO) method was more suitable for fitting the pyrolysis process to obtain activation energy (Ea) with higher R2 (0.94714–0.99640) compared with Kissinger-Akahira-Sunose (KAS) method. When the mixing ratio of cellulose and PET was 1:1, the Ea was significantly reduced to 80.73 KJ/mol, and further reduced to 73.04 KJ/mol by introducing the catalyst, as compared to Ea of individual cellulose (178.95 KJ/mol) and PET (198.34 KJ/mol). Co-pyrolysis of cellulose and PET led to a reduction of carbohydrates, furans, alcohols, ketones, and phenols, while the content of acids was remarkably increased which was consistent with the observation in FTIR that the absorption peak of C＝O became sharp and strong. The introduction of ZSM-11 resulted in an increase in aromatics and a decrease in acids content owing to aromatization and deoxygenation. This work is expected to offer beneficial guidance for the efficient disposal of MSW and the application of deep learning methods.

Facilitating Solid Waste Handling System in Port Harcourt Cosmopolis

Port Harcourt cosmopolis grappled with a continual rise in municipal solid waste (MSW) generation. The increase is a consequence of an advance in population rise and consumption pattern. The paper reports an approximate valuation and depiction of municipal solid waste with emphasis from questionnaire survey on socio-economic status of the inhabitants in the zones that make up the cosmopolis. The methodology and procedure for this investigation obtained using vehicle selection approach centered on ASTM D5321 standard test method for ascertaining the constituents of municipal solid waste. Specimens were sorted into fourteen waste classifications of paper; 6.22%, pasteboard; 2%, plastic film; 9.05%, dense plastic; 2.73%, glass; 2.3%, iron-based metal; 3.03%, non-iron based metal; 1.13%, putrescibles; 56.3%, textiles; 1.85%, misc-ignitable; 2.83%, non-misc ignitable; 3.35%, E-waste; 2.33%, household waste; 4.88% and fine elements; 2.03%. The outcome shows an average 56.3% of municipal solid waste specimens discovered to be biodegradable. This is suitable for composting activities. Aside biodegradables, there exist, paper glass, dense plastics, and iron-based metals, which are recyclables. This is significant for providing gainful employments to the inhabitants of the cosmopolis. On the contrary, there were about 2.83% of misc-ignitable. This is suitable for energy recovery. There was a variation in specimens of MSW in all the zones that make up the cosmopolis, attributing it to changes in disparity in incomes. It is necessary for government to legalize, recycling and composting activities, which based on the waste management hierarchy process in a manner that ensures environmental sustainability, economic sustainability, and global acceptance.

Yard wastes generation, management and utilization in nigeria

Yard waste is a major constituent of municipal solid waste (MSW) that contain elements that can be used by microorganisms during biological degradation of MSW but whose economic values are less than the cost of collection, transportation, and processing for beneficial use. It is generated from the gardens, plant nurseries, road sweepings, and so on. Yard waste generation is inevitable in any society, and it is clear that rapid urbanization has resulted in significantly more yard waste generation than previously. Gardening is common in communities, whether rural and urban, resulting in garden wastes such as leaves, wood trimmings and grass clipping. At present, most of the yard wastes in Nigeria are illegally dumped into abandoned waste lands or burn up which is very harmful and had raised concerns for the environmental and human health. However, due to a lack of corresponding policy support and management requirements for yard waste usage in Nigeria, this study proposes remedies and proposals for yard waste utilization that are appropriate for Nigeria, based on successful technologies and regulations. So based on the real situation in Nigeria, it is imperative to replace the traditional methods of yard waste management with innovative ones to promote their proper utilization..

Physicochemical Properties of Torrefied and Pyrolyzed Food Waste Biochars as Fuel: A Pilot-Scale Study

Food waste is an important constituent of municipal solid waste, and research has been conducted to develop various methods for treating food waste and recycling it (e.g., fuel, landfilling, composting, conversion into animal feed, drying, and carbonization). Among these, the drying and carbonization techniques can change food waste into fuel; however, they need more energy than fermentation and anaerobic digestion procedures. In this study, we investigated the physicochemical properties of food waste biochar produced under torrefaction (270 °C) and pyrolysis (450 °C) conditions to establish its applicability as fuel by comparing temperatures, residence times, and conditions before and after demineralization. The higher heating value increased after the demineralization process under both temperature conditions (270 °C and 450 °C), and the chlorine level was lower at 270 °C temperature demineralization than at 450 °C. During the demineralization process, Na and K were better removed than Ca and Mg. Additionally, Cr, Hg, Cd, and Pb levels were lower than those according to the European Union and Korean domestic bio-SRF recovered fuel criteria, confirming the applicability of biochar as fuel.

Retort-heating carbonisation of almond (Terminalia catappa) leaves and LDPE waste for biochar production: evaluation of product quality

ABSTRACT The aim of this study was to utilise a top-lit updraft biomass conversion reactor with retort heating for the production of biochar from dry almond (Terminalia catappa) leaves and Low-Density Polyethylene (LDPE) waste (biomass-plastic mass ratio of 35:1). The feedstock was chosen to serve as a typology of each of the two major constituents of municipal solid waste (MSW). The study was done to examine the process performance and product yield and quality. A yield of 28.57 wt% for the biomass biochar and 71.43 wt% for the hybrid biochar was achieved at a peak temperature of 494°C and 362°C respectively in 90 minutes. The products were characterised using Fourier Transform Infrared Spectroscopy (FTIR), Scanning Electron Microscopy (SEM) and Branueur–Emmett–Teller (BET) analyses. The biomass biochar and the hybrid biochar have a specific surface area of 450.2 m2/g and 296.8 m2/g respectively and both products was mesoporous. It is observed that retort heating carbonisation can be used to convert almond leaves and LDPE waste to biochar usable as an adsorbent. The work is of benefit in converting MSW to a useful product. These are helpful in waste minimisation, environmental protection.

Municipal Solid Waste Quantity, Ingredients, and Site Disposal Problems in Pshdar District in Sulaimanyah: Iraqi Kurdistan Region, Iraq

Over the past years, the high generation of municipal solid waste has been identified as a considerable global environmental issue, due to population growth, economic development, and the industrial revolution. The present research study was conducted to evaluate the quantity, ingredients, and generation of municipal solid waste (MSW) in Pshdar district during winter and summer in 2019. The results revealed that the average of solid waste production in the district reached 94 tons/day and 0.761kg-capita/day. The most abundant MSW constituents are organic matter forming 75.71% of MSW of the district, followed by 13.18% of plastic content and the least ingredient is metal 0.93%. While the average ratio of paper and cardboard, textile and leather, and glass waste ingredients are 3.74%, 4.85%, and 1.66% respectively. The seasonal effect on solid waste content has been observed obviously in this research, more specifically in organic matter and textile & leather, as well as in waste generation rate. Organic matter increased from 70.73% to 80.68% from winter to summer, while, percentage of textile and leather significantly declined from 6.93% to 2.76% from winter to summer. Similarly, waste generation rate was reduced from wet to dry season from 0.846kg-cap/day to 0.676kg-cap/day.

Polyhydroxyalkanoate (PHA) Production Using Volatile Fatty Acids Derived from the Anaerobic Digestion of Waste Paper

Waste paper as a resource for polyhydroxyalkanoate (PHA) production through anaerobic digestion is a low-cost strategy to produce bioplastic. In this study, volatile fatty acids (VFAs) produced from waste paper, one of the significant constituents of municipal solid waste, was utilized as a feedstock for polyhydroxyalkanoate (PHA) production. PHA production from synthetic VFAs by Cupriavidus necator was initially optimized under different VFAs concentrations, VFAs ratios, and nitrogen sources. VFAs concentration of 10 g/L, 5:1:4 ratio of acetic, propionic, and butyric acids (HAc:HPr:HBu) and NaNO3 as nitrogen source were considered the optimum conditions with 56.98% PHA and 0.31 g/g yield. Anaerobic digestion of shredded office paper (OP/S) produced the maximum VFAs (521.50 mg/L) after 15 days of incubation and were utilized for PHA synthesis. Almost 2.24-fold increase in the yield of PHA was achieved with limited nutrient medium compared to nutrient contained medium with a PHA content of 53.50 and 23.88%, respectively. PHA production using anaerobic effluent of waste paper is a promising approach where a series of pretreatment processes, the expensive enzymatic hydrolysis, and detoxification were no longer required, suggesting an environmentally friendly way of biopolymer production.

Sustainable financing for municipal solid waste management in Nepal.

Financing municipal solid waste (MSW) services is one of the key challenges faced by cities in developing countries. This study used plastic waste, a constituent of MSW, to explore the possibility of generating revenue for financing MSW management in the municipalities of Nepal. The results of this study suggest that plastic material recovery could generate revenue, which is equivalent to 1.38 times of the plastic-waste-related management cost when collection efficiency reaches 66.7%. An increase in 1% of recovery rate and collection efficiency could cover an additional 4.64% and 2.06% of the costs of managing plastic waste, respectively. In addition, an increase in tax on imported plastic materials could also motivate recovery of plastic waste for recycle and reuse. An additional 1% tax on plastic imports would be sufficient to cover plastic-related waste management when plastic waste recovery and collection efficiency rates are low. This plastic recovery- revenue exercise could be expanded to other materials such as paper and metal to fully understand the possibility of sustainable financing of MSW management and reducing environmental harm in developing countries like Nepal.

Municipal Solid Waste Characterization as a Measure towards Sustainable Waste Management in Abuja, Nigeria

The constant generation of Municipal Solid Waste (MSW) is a global concern in terms of quantity and its variety. The composition of MSW is influenced by the level of income; the season of the year; population; culture and lifestyle of people living in that community. Nigeria, in particular, is currently struggling with the menace of the upsurge in the quantity MSW in her major cities, but concern only with its collection, transportation, and disposal, however neglecting the prospect of material recovery from MSW for recycling. On this note, the study aimed to characterize MSW from identified dumpsites and at household level in Abuja Municipal Area Council (AMAC) and Bwari area council, Abuja, Nigeria towards a sustainable and efficient MSW management. The methodology used in this study was carried out in both wet and dry seasons, and each season entails; the use of American Standard Test Method [1] to determine the composition of unprocessed MSW at dumpsites 3 days in a week for 4 weeks and, the segregation of MSW into colored bags representing waste category at the household level was done for 2 weeks. The use of a stratified and random sampling method was employed to administer the questionnaires for data acquisition. The results show that the level of income played a significant role in the constituents of MSW generated at district level. In conclusion, food waste/organics and plastic waste are the predominant MSW categories in AMAC, and Bwari area council, Abuja, Nigeria. The characterization of MSW is essential for a long-term effect and sustainable solid waste management plans in order to design an appropriate and efficient waste management system for the society.

Production of bioplastic (poly-3-hydroxybutyrate) using waste paper as a feedstock: Optimization of enzymatic hydrolysis and fermentation employing Burkholderia sacchari

The global demand for bio-plastic particularly polyhydroxyalkanoate (PHA) have been increased in the last few decades as a substitute of petrochemical-based plastic. Utilization of waste paper, the primary constituent of municipal solid waste (MSW), as a carbon source for polyhydroxybutyrate (PHB) production is not only an alternative, environmental friendly route of waste management but also helps to valorize the waste. In this study, hydrogen peroxide pretreated waste paper saccharification has been optimized using central composite design (CCD). The maximum hydrolysis (88.18%) occurred at paper loading 5.0 g/L, agitation 242 rpm, working volume 20%, cellulase 49.82 U/g, β-glucosidase 20.9 U/g and hemicellulase 29.5 U/g. PHB synthesis and biomass accumulation by xylose-utilizing Burkholderia sacchari using waste paper hydrolysate were studied using different nitrogen sources and carbon to nitrogen (C/N) ratios. Maximum PHB and dry cell weight (DCW) occurred with ammonium sulfate and a C/N ratio of 20. The highest biomass (3.63 g/L), the maximum PHB accumulation (44.2%) and the maximum reducing sugar utilization (92.1%) were observed after 48 h of cultivation using diluted hydrolysate. The physicochemical properties of the extracted PHB were compatible with the standard PHB. Hence, the waste paper could be exploited as a renewable feedstock for the sustainable production of PHB.

Analysis and forecasting of municipal solid waste in Nankana City using geo-spatial techniques.

The objective of this study was to analyze and forecast municipal solid waste (MSW) in Nankana City (NC), District Nankana, Province of Punjab, Pakistan. The study is based on primary data acquired through a questionnaire, Global Positioning System (GPS), and direct waste sampling and analysis. Inverse distance weighting (IDW) technique was applied to geo-visualize the spatial trend of MSW generation. Analysis revealed that the total MSW generated was 12,419,636kg/annum (12,419.64t) or 34,026.4kg/day (34.03t), or 0.46kg/capita/day (kg/cap/day). The average wastes generated per day by studied households, clinics, hospitals, and hotels were 3, 7.5, 20, and 15kg, respectively. The residential sector was the top producer with 95.5% (32,511kg/day) followed by commercial sector 1.9% (665kg/day). On average, high-income and low-income households were generating waste of 4.2kg/household/day (kg/hh/day) and 1.7kg/hh/day, respectively. Similarly, large-size families were generating more (4.4kg/hh/day) waste than small-size families (1.8kg/hh/day). The physical constituents of MSW generated in the study area with a population of about 70,000 included paper (7%); compostable matter (61%); plastics (9%); fine earth, ashes, ceramics, and stones (20.4%); and others (2.6%).The spatial trend of MSW generation varies; city center has a high rate of generation and towards periphery generation lowers. Based on the current population growth and MSW generation rate, NC is expected to generate 2.8 times more waste by the year 2050.This is imperative to develop a proper solid waste management plan to reduce the risk of environmental degradation and protect human health. This study provides insights into MSW generation rate, physical composition, and forecasting which are vital in its management strategies.

COMPOSTING OF ORGANIC WASTE WITH THE USE OF MINERAL ADDITIVES

Aerobic composting is one of the best available technologies for an integrated waste management system in terms of minimizing the anthropogenic impact on the environment, complying with the latest domestic and foreign developments, economic and practical acceptance of the technology. Organic production is rapidly spreading in the world as a holistic system of rational nature management that becomes the basis for the use of modern composting technologies for organic raw materials to obtain a quality product of processing. But composting is characterized by relatively low popularity in comparison with other methods of waste utilization due to a number of its disadvantages, such as a long production cycle and sometimes the unstable quality of a product obtained. Because of this, many studies in the field of solid waste recycling are devoted to methods of accelerating the composting process. This can be achieved in various ways, such as the development of high–performance composting machines and biotic changes (vermiculture, use of specialized crops and biocenoses of microorganisms), or abiotic (temperature, pH, etc.) parameters of the process.The article presents the results of studying the effect of mineral additives on organic waste composting processes, with the aim of its accelerating in mesophilic and thermophilic temperature regimes with controlled parameters. To improve the efficiency of the composting process and compare the features of the processes, the soil was used as a microbiological inoculum, and mineral salts solutions as a mineral additive. The results of the studies allow us to conclude that it is advisable to compost plant waste with a mineral additive, both in the thermophilic and the mesophilic mode. The compost ripening period, with a mineral additive used, is 6 weeks. It is shown that the mineral complex accelerates the composting of the organic constituent of municipal solid waste by 2.2 times in the thermophilic mode, and by 1.4 times under the mesophilic conditions of the composting process, which proves the effectiveness of its use in recycling municipal solid waste to increase the general level of environmental safety.

Assessing the physicochemical properties and quality parameters during composting of different organic constituents of Municipal Solid Waste

This experimental work aimed to assess the physicochemical properties and quality parameters in different substrates during composting of organic constituents of Municipal Solid Waste (OCMSW) for a period of 40 days. Three different runs were set up respectively in three 244 L in-vessel systems and designated as R1, R2 and R3. R1 depicted the food waste mix; R2 represented the paper waste mix and R3 for the yard waste mix. pH values in the three runs showed an analogous varying range and decreased to 7.4–7.5. The net degradation of the composting matrix in respect of volatile solids diminution was 77.71%, 61.19%, 62.26% for R1, R2 and R3 respectively. The data of Carbon to Nitrogen (C/N) ratios demonstrated a general decrease of 22.8% − 28.1% in final mixtures. R2 had the highest water holding capacity of 4.71 ± 0.64 (471%) among others. The final nutrient contents P, K, Ca, Mg and Na showed an increase as compared initially. The experimental analysis pointed out that different element influenced compost quality and the quality of the end product can be evaluated by several parameters in order to ensure its safe use in the cultivation of crops. Results demonstrated that composting of OCMSW as an appropriate management practice for the remediation of toxic heavy metals. There is a great scope for an extensive application of composting technology on a nationwide basis and the qualitative information reported on the compost quality parameters may permit its utilization by the public.

ENERGY VALUE IN BIOMASS AND PLASTIC COMPONENTS OF MUNICIPAL SOLID WASTE

Burning potencies of constituents of municipal solid waste (MSW) indicate energy value stored in them. A significant portion of biodegradable as well as non-biodegradable waste is still80 not recycled and most of them are either burnt or dumped in the landfills. The scope of this work is to study the energy value of selected biomass (dry garden leaves) and two plastic materials, low density polyethylene (LDPE) and polystyrene (PS), collected from an educational campus in Varanasi, India. Cow dung which is still used as domestic fuel in dry cake form in many parts of the country, has also been included. Two pellet batches of biomass, one each of Ashoka (Saraca Asoca) tree leaves and Cow dung, two pellet batches of plastic, one each of low density polyethylene (LDPE) and polystyrene (PS); and twelve biomass-plastic blended pellets have been prepared and tested. Proximate analyses and higher heating values (HHVs) were measured and compared with the gross calorific values (GCVs) of various grades of Indian non-coking thermal coals. The results indicate that on blending of biomass materials with plastics in 1:1 ratio, the HHV of mix exceed GCV of grade A non-coking coal. A 2:1 ratio gives material with heating values higher than grade C coal. Other tested mix proportions also produced heating values exceeding D grade coal. Thus, it appears feasible to produce secondary fuel using components of MSW for domestic consumptions. This is a non-conventional and renewable source of energy. This may partly reduce the dependence on fossil fuel (like coal) and provide an alternate reuse pathway for such materials.

Reliability-Based Assessment of Municipal Solid Waste Landfill Slope

AbstractA reliability-based assessment of municipal solid waste (MSW) landfill slope is presented in this study, keeping in mind the large variability in MSW constituents and their mechanical properties. Typical slope geometry consisting of several layers of MSW with varying stages/degrees of decomposition is considered in consistence with evolution kinetics. A number of representative snapshots of the evolution in time are considered to capture a pseudotemporal picture of the evolution of the slope reliability. The analysis of slope employs the finite-element method in order to calculate the factor of safety, which is subsequently used in defining the limit state of failure. The limit state is then employed for the assessment of slope reliability. Repeated computation of the safety factor/limit state is avoided by adopting a response surface (RS)-based metamodeling approach. It is observed that the moving least-square-based RS provides an improved estimate of slope reliability than the conventional least...

Preliminary Study of PM2.5 Formation During Municipal Solid Waste Incineration

Air pollution, especially PM2.5 pollution in atmosphere, is serious in China and municipal solid waste incineration is one of the major emission sources of PM2.5. In order to find out the mechanism of PM2.5 formation during incineration, experiments were performed. Firstly, real constituents of municipal solid waste were conducted by a literature survey; secondly, each constituent was incinerated in tube furnace respectively and together according to survey results, in all 7 treatments. They were kitchen waste, sawdust, plastic, paper, rag, glass and mixed rubbish comprising each constituent. Meanwhile PM2.5 was collected and weighed; finally, according to constituent ratio and PM2.5 mass each constituent produced, the simulate value of mixed rubbish was calculated. The results showed that among the single constituent incineration experiments, plastic accounted for more PM2.5 mass than any other constituents. And the followings were rag, kitchen waste, paper, sawdust and glass. Plastic produced 20.5725mg (PM2.5)/ g (plastic) which is approximately 4 times than rag, 5 times than kitchen waste. Glass produced least only 0.2472mg (PM2.5)/ g (glass). Compared with single constituent incineration, PM2.5 which mixed rubbish produced was only less than rag's. The simulate value of PM2.5 mixed rubbish produced was 4.9108mg (PM2.5)/g (simulate sample), which is more than the value (4.2929mg (PM2.5)/g (mixed rubbish)) the real mixed rubbish produced. This proved there was a probability that inhibitory effect existed during mixed rubbish incineration. And the inhibition effect was up to about 0.6179mg (PM2.5)/g (mixed rubbish).

Production of Bioethanol from Waste Newspaper

Paper, which is one of the largest constituent of Municipal solid waste, has become a severe problem for disposal in developed and developing countries due to the shrinking landfill capacity. It is very important and challenging task in managing the solid waste. Newspaper, which is a cellulosic feed stock, is emerging as an attractive option for the production of bio-ethanol because of lower feedstock costs, higher potential for fossil fuel displacement and also there will be reduction in greenhouse gas emission as compared to production of ethanol from corn. The main objective of the current project is to minimize the newspaper load on municipal solid waste by efficiently utilizing the waste newspaper in the production of bio-ethanol. Experimental studies have been carried out to optimize the pre-treatment process for increasing the efficiency of bacterial hydrolysis, the efficient conversion of cellulose to sugars from cellulose degrading microorganisms and to convert the sugars released to Ethanol by using Fermentation process. Pretreatment, hydrolysis and fermentation are the steps involved in the production of Bioethanol. In the pre-treatment process, the Lignin, Hemicellulose and Cellulose are separated to enhance the hydrolysis process. The optimized condition for the pre-treatment was found to be 1.5% concentration of H2SO4 at 121 °C and 45 minutes. The bacteria CytophagaHuchnosonni was used for hydrolysis process, which helped in converting the cellulose to sugars and was analysed using DinitroSalicilicacid. The reducing sugars were fermented to produce Bioethanol using the Yeast Saccharomyces Cerevisae and the yield was estimated using specific gravity method and also by using HPLC.
