Organic Waste Treatment

Developing countries face serious environmental, social and economic challenges in managing different types of organic waste. Proper treatment strategies should be adopted by solid waste management systems in order to address these concerns. Among all of the treatment options for organic waste, composting is the most approved method as an effective strategy to divert solid waste from landfills. This experimental research aimed to examine the potential of producing compost from source-separated municipal organic waste in Shiraz, Iran. Market waste (fruits and vegetables) and garden waste (plant residues) were used as the raw input materials. They were subjected to the windrow pile composting method in an open site area. The process was monitored against several physical, chemical and biological parameters. In-situ measurements (temperature and moisture content) were carried out on a daily basis. Sampling and lab analyses were conducted over the period of the biological treatment. The final product was of acceptable moisture and nutrient levels, pH, Electrical Conductivity (EC), and Carbon/Nitrogen ratio. All of the analyzed compost samples had lower concentrations of heavy metals than the Iranian and German standards. Overall, the results obtained revealed that composting is a promising method for municipal organic waste treatment. The findings also imply the effectiveness of the source-separation collection method in the production of high-quality compost.

Municipal Organic Solid Waste

This study proposed action scenarios for urban solid waste management in six municipalities in the Corumbataí River Basin. The operating scenarios were designed for organic waste treatment and for the shared disposal of urban solid waste. Six municipalities were studied, five of which had less than 30,000 inhabitants (Analândia, Charqueada, Corumbataí, Ipeúna, and Santa Gertrudes). In addition, Rio Claro had 199,000 inhabitants. Thus, the transport and transshipment stages, general infrastructure, and final disposal in landfills were analyzed. Further, the three scenarios for organic waste treatment were conducted separately. The items and the cost of implementation were estimated for decentralized composting, centralized composting, and biomethanization of waste with electricity recovery. The biomethanization scenario included the commercialization of electricity, so it generated revenues that decreased costs. This cost reduction was especially notable in the last years of the project when the goals of diversion of organic waste through selective collection were higher. The results suggested that the investigated scenarios could improve organic waste treatment and that the biomethanization scenario with electricity generation presented lower average costs per inhabitant than the centralized and decentralized composting scenarios.

Emission Of Greenhouse Gases

The research is aimed at comparing different methods of municipal solid waste treatment (waste burial, composting, complex recycling) depending on the values of generated greenhouse gases. In order to compare waste burial and composting of municipal solid waste based on amount of generated greenhouse gases the calculation methods used for compiling the National Inventory, were taken.  The mass balance method was used to estimate the output of a product of complex recycling. The municipal solid waste components differ by amount of degradable organic carbon and decomposition rate but have the largest mass. The municipal solid waste treatment techniques consist in placing such waste at landfills and dumps which are sources of environmental pollution, for example, by greenhouse gases. There are other organic waste treatment methods, such as composting via different technologies, burning, recycling etc. But all of them are also associated with greenhouse gases emission. Easily decomposed organic waste can be used for production of organic fertilizers, but a mandatory requirement, that is separation from the general municipal solid waste stream at the time of waste production, should be complied with. A complex recycling of easily decomposed organic waste, including anaerobic and aerobic composting is offered as an efficient way of waste management. The article presents a comparative analysis of various methods of municipal solid waste treatment based on the amount of greenhouse gases emitted in the Odessa Region. It considers three waste treatment approaches: all waste mass is to be placed at landfills and dumps, composting of some of park and garden waste and burial of other components, complex recycling of food, park and garden waste and some of paper waste according to the developed scheme. Complex recycling offers the least value of total greenhouse gases emission over a five-year period whereas waste disposal is characterized by the highest value thereof.  The complex recovery of components containing bioavailable organic carbon through anaerobic fermentation method excludes emission of greenhouse gases into the atmosphere, as the biogas produced can be collected and extracted. However, over a long period, even after two-stage complex recycling, the total emission of greenhouse gases will be lower comparing to other methods of easily decomposed organic waste treatment. Emission of greenhouse gases in case of waste disposal has a prolonged nature whereas emission of greenhouse gases in case of composting occurs within a short period of time which should be taken into account when analyzing the prospects of solving the municipal solid waste problem.

Organic Waste Treatment

Organic waste is the largest composition of waste generated by the people of Indonesia, which is around 50-60%. This type of waste, especially food waste, is easy to smell if it is stored for too long so that it has the potential to pollute the environment. On the other hand, organic waste has good nutrients that can be generated, including through BSF (Black Soldier Fly) maggot bioconversion treatment. The BSF maggot bioconversion method is a method of processing organic waste which is carried out by converting organic matter into other products that are useful and have added value by utilizing biological processes from microorganisms and enzymes. Organic waste treatment with this method is generally carried out on a community-based basis and is integrated with the development of agriculture, fisheries and animal husbandry, because maggot cultivation produces commodities of economic value such as compost and maggot larvae. Compost contains very good nutrients so that it can be used for organic farming and maggot contains high protein that can be used for animal feed and fisheries. The implementation of this program was piloted in the boarding school community, namely the Az-Zakaria Islamic Boarding School which is managed by the Az-Zakaria Islamic Education Foundation (YPI) in Sindangbarang Village, Jalaksana District, Kuningan Regency. The result of this implementation is the formation of a new group of entrepreneurs engaged in the cultivation and utilization of BSF maggots.

The solid wastes generated as a result of human activity have become very complex. Unscientific management of such wastes has resulted in environmental pollution, thereby putting a serious risk to the ecosystem and human health. A sustainable waste management is required for reduced pollution levels as well as for safeguarding the environment for future generation. Biological methods have gained in importance mainly because of its environmentally friendly option for recovering materials and energy. This is true as per the guidelines of “Hierarchy of Sustainable Waste Management.” Composting and anaerobic digestion are two treatment options that is commonly followed in both developing as well as developed countries. The aim of this chapter is thus to address the technical background, advantages, as well as shortfalls related to the waste treatment via biological methods. An up-to-date literature thus presented may be beneficial to the scientists and researchers for working towards further improvement of the present system of waste management.

Risk Assessment And Management

Bioaerosol characterization represents a major challenge for the risk assessment and management of exposed people. One of the most important bioaerosol sources is the organic waste collection and treatment. This work analyzed and discussed the literature with the purpose of investigating the main techniques used nowadays for bioaerosol monitoring during organic waste treatment. The discussion includes an overview on the most efficient sampling, DNA extraction, and analysis methods, including both the cultural and the bio-molecular approach. Generally, an exhaustive biological risk assessment is not applied due to the organic waste heterogeneity, treatment complexity, and unknown aerosolized emission rate. However, the application of bio-molecular methods allows a better bioaerosol characterization, and it is desirable to be associated with standardized cultural methods. Risk assessment for organic waste workers generally includes the evaluation of the potential exposition to pathogens and opportunistic pathogens or to other microorganisms as biomarkers. In most cases, Saccharopolyspora rectivirgula, Legionella spp., Aspergillus spp., and Mycobacterium spp. are included. Future perspectives are focused on identifying common composting biomarkers, on investigating the causality process between chronic bioaerosol exposure and disease onset, and finally, on defining common exposure limits.

The Government

The increase of solid waste production is a general problem in municipality, particularly of plastic waste. The durability, light-weight, anticorrosiveness, and inexpensiveness properties of plastic make it favorable to be used in daily life, including in Salatiga. However, plastic is one of some non-biodegradable materials that could lead to soil and water pollution as it contains toxic compounds such as aromatic hydrocarbons, phthalates, and organochlorine. Various studies in municipal solid waste management have been conducted. While those studies often applied various approaches separately, researches in regard to the role of stakeholders in municipal solid waste management are very limited. This study aims to explain the plastic waste management in Salatiga based on the role of the corresponding stakeholders. This qualitative study shows that there are four stakeholders who were involved in municipal plastic waste management in Salatiga. They were the households who generate wastes, the scavengers who sorts the wastes, Bank Sampah and collectors who have the same role in order to collect the wastes and treat the plastic wastes through reusing or recycling processes, and the government. Currently, efforts in waste treatment in Salatiga are focused on the system of collecting-tranferring-disposal mode, waste treatment by reuse and recycle processing, and landfilling. Reducing plastic consumption must take into account the sociocultural aspect and environmental awareness, as the people still interested to use plastic instead of using other materials in substitution. Finally, the role of government is central to educate the community in term of sorting activities and reducing waste production, build the capacity of Bank Sampah, and manage the role of scavengers and collectors. Other alternatives include creating synergy between the collectors and Bank Sampah, as well as ensuring final treatment of the unprocessed wastes disposed by collectors and Bank Sampah.
