Soil Detoxification

The technology on separation of the solid wastes at the municipal waste landfills obtaining solid waste and soil, which is sanitized with the use of natural sorbent "Agroionit" is suggested. It showed that sorbent "Agrionite" application in the amount of 16 % in absolutely dry matter could reduce the content of mobile forms of heavy metals up to MPC. To reduce the amount of sorbent up to 12 % pre-treatment of soil with lime in the amount of 0,4 % for the detoxification of zinc, which is slowly absorbed by Agrionite is required. Appropriate changes to the developed technology have been added, including the regulation of temperature and humidity of soil.

Waste is a product of society and one of the biggest challenges for future generations is to understand how to sustainably dispose of large amounts of waste. The main objective of this study was to determine the possibility and conditions of the decentralized combustion of non-hazardous municipal waste. The analysis of the combustion properties of a mixture of wood chips and 20–30% of municipal solid waste showed an improvement in the operating parameters of the combustion process. Analysis also confirmed that the co-combustion of dirty fuels and biomass reduced the risk of releasing minerals and heavy metals from fuel into the natural environment. Approximately 55% of the heavy metals passed into the ash. The analysis of municipal solid waste and fuel mixtures containing municipal solid waste for polycyclic aromatic hydrocarbons showed the risk of increasing polycyclic aromatic hydrocarbon concentrations in flue gases.

The use of major nutrient-containing solid residuals, such as recycled solid waste materials, has a strong potential in closing the broken nutrient cycles. In this work, biofuel ash (BA) combined with green waste compost (GWC) was used as a nutrient source to improve soil properties and enhance wheat and triticale yields. The main goal was to obtain the nutrient and heavy metal release dynamics and ascertain whether GWC together with BA can potentially be used for concurrent bioremediation to mitigate any negative solid waste effects on the environment. Both BA and GWC were applied in the first year of study. No fertilization was performed in the second year of the study. The results obtained in this work showed the highest spring wheat yield when the GWC (20 t ha−1) and BA (4.5 t ha−1) mixture was used. After the first harvest, the increase in the mobile forms of all measured nutrients was detected in the soil with complex composted materials (GWC + BA). The content of heavy metals (Cd, Zn, and Cr) in the soil increased significantly with BA and all GWC + BA mixtures. In both experiment years, the application of BA together with GWC resulted in fewer heavy metals transferred to the crops than with BA alone.

The soil and water contamination by metals from hazardous waste confined with urban solid wastes, highlights the importance of enhance the monitoring of disposal sites once closed. It is common to fail to comply with the regulations on their location, operation and post-closure, and located in areas that affect the environment and the health of the population. In the closed dump of Morelia, contamination of the soil and groundwater by leachates with heavy metals in the water from supply wells has been reported. The objective of this study was to determine the presence of heavy metals and arsenic in the confined wastes of the Morelia closed dump, in order to diagnose the affectation from the contaminants. Composition, degradation status and the presence of heavy metals were analyzed in samples of confined solid wastes from eight wells with different age of confinement. The results of this study ratify the contamination of the leachates of the site and are associated with the contamination of the water for human consumption in the area. The actual regulation does not apply in the case of urban solid waste, so it is crucial to regulate monitoring and management for correct decision-making during post-closure management.

This report focuses on the potential for using waste carpets as part of cover and liner systems at municipal solid waste landfills. Five different carpet materials were tested for their characteristics before and after incorporation with solid wastes in simulated landfill bioreactors. Selected analyses are presented on heavy metals and volatile organic compounds from TCLP extracts, and on leachate and gas samples during operation with and without leachate recycle. Biological clogging tests indicated no alteration in carpet integrity o2r significant reduction in permeability. Solid waste stabilization, indicated by gas and leachate parameters, proceeded without adverse impact from the codisposed carpets. Volatile organic compounds and heavy metals were present in trace amounts and below regulatory limits. These results supported post-consumer use of carpets as filter and separation layers for municipal solid waste landfill cover and liner systems.

Abstract Refuse-derived fuel (RDF) can be produced from combustible materials contained in municipal waste. After pre-treatment of waste it is possible shipping RDF a waste-to-energy plant (WtE). This article investigates energy and material flow of waste for different scenarios for production of RDF from bulky waste, separately collected waste, and mixed municipal solid waste (MSW). We compare the proportion of energy consumption in transportation, handling waste, and processing using data from the waste collection company in the South of Poland. The findings show the components of the reverse supply chain consuming the highest value of the energy. A model of material and energy flow has taken into consideration collection of waste and transportation by two categories of waste collection vehicles light commercial vehicles and garbage trucks. The shipping of RDF from pre-treatment facility uses – tipper semi-trailers and walking floor trailers. The findings of the study show production of RDF from municipal solid waste is consuming almost 10% of energy potential in RDF. Less energy is required for the production of RDF from bulky waste 2.2% – 4.8% or separately collected waste 1.7% – 4.1% depending on the efficiency of collection and selected vehicles. The transportation is consuming greatest portion of energy. For mixed municipal solid waste (MSW) it can reach 79%, for separated collection waste 90% and for bulky waste up to 92% of the total energy consumed. Comparing emissions for two categories of the collection vehicles there is no significant difference for the bulky waste collections. For mixed MSW and separately collected waste the emissions are higher for garbage trucks. As a recommendation for practitioners is optimization of routing to achieve higher collection rate for minimized route length. Transportation of RDF to WtE plant the vehicles with higher loading capacity are essential.

Due to the development of Industrialization and urbanization, a wide variety of industrial and consumer products, by products and solid waste has been produced. The solid waste generated constitutes the hazardous substance which possesses certain impacts on humans and their environment. In that heavy metal pollution from industries are the serious environmental problems. Rapid development in industries in the last few decades resulted in the strenuous task for finding to manage the waste generated. These hazardous solid wastes have been formulated into reusable end product by the process of bioremediation. Bioremediation is a natural process, which involves the use of organism to remove or neutralize the toxic pollutant from the contamination site. This review focus on the toxic effects of heavy metals on the environment and on the human health as well as the possible bioremediation method of these metals using fungus and earthworm. In order to conserve the environment and resources, the biological remediation by both fungus and earthworm for heavy metals and their efficiency have been summarised in detail.
