Abstract:

Pentachlorophenol (PCP) has been used as a biocide and preservative for wood power poles and crossarms. If disposed in landfills, the natural capacity of landfills to transform hazardous constituents to less hazardous or inert substances may also apply to such PCP-treated materials. The principal reaction of interest in the anaerobic environment of a landfill is reductive dechlorination. The fate and transformation of PCP-treated wood was investigated in simulated landfill bioreactors operated under single pass leaching and leachate recirculation. The wood samples consisted of 2% of the total

Abstract:

This study estimates the overall cost savings that have been realized due to disposal of inert wastes in Japan because this material has been deposited in inert waste landfills (IWLs) that are designed exclusively for this purpose, instead of being co-dipsosed with organic wastes in more costly in sanitary landfills (SLs). The total realized cost savings were based on the disposed volume of inert waste and the actual disposal fees for IWLs and SLs for the period 1977–2006. The estimated reduction in expense is 4748 billion JPY for the period. On the other hand, if organic wastes had been depos

To reduce the amount of MSW going to landfills a number of technologies have been developed. Two main types of anaerobic digestion processes are distinguished for MSW organic waste, which are generally referred to as “wet” (10-15% DM) and “dry” (24-40% DM) anaerobic digestion processes. The input is conditioned to the appropriate DM content by adding process water as required. This article compares a full-scale dry process, Valorga in La Coruña, Spain and a wet process, Vagron in Groningen, The Netherlands. A crucial difference is that the Vagron facility applies a washing step prior to the AD

Anaerobic digestion of residual municipal solid waste (MSW) has become more important than the digestion of source separated biowaste. More than 52% of the capacity available in Europe was designed for digestion of residual municipal waste by the end of 2006, while this was only 13% in 1998. Partial digestion of residual waste organics, by which only a part of the organics is digested, has been implemented to reduce the need for dewatering and subsequent wastewater treatment. The digestate coming from part of the organics is immediately mixed with the non-digested organic fraction. This organi

Abstract:

A numerical model links the build-up of mineral precipitate (primarily CaCO3) and the anaerobic activity of biofilms, which occur in granular material permeated with leachate from a municipal solid waste landfill. The model represents the porous-media flow system as a collection of elements in which each element acts as a separate, fixed-film reactor. The model represents biofilm growth for microorganisms carrying out acetogenesis of propionate and methanogenesis of acetate. It also directly links substrate utilization to mineral precipitation and accounts for the accumulation of inert biomass

Abstract:

Construction and demolition waste (CDW) accounts for 40% of urban municipal waste in China and around 25% in the European Union (EU). Since the EU is more developed and urbanized than China, its experience with managing CDW may be helpful to China. This study therefore compared China and the EU with respect to the flow of CDW materials and the policies, laws and regulations for CDW management. The results reveal that the CDW management practices and facilities in China are relatively underdeveloped with a large amount of low-value inert material going to landfill compared with the EU.

Abstract:

In the present study, the authors assessed the odour quality of the air in the vicinity of a landfill site using a case study of a waste management plant that processes non-hazardous and inert waste as an example. An analysis of the impact of the facility under study on the odour quality of the air was performed based on a mathematical modelling system used to, among other things, assess the impact of investments in air quality both in Poland and worldwide. The most important element of the system is the puff dispersion model CALPUFF. In conclusion, the analysis of the plant’s odour impact cle

Informal incineration or open pit burning of waste materials is a common practice in the peripheral area of Dhaka, one of the fastest growing mega-cities in the world. This study deals with the effect of open pit burned (i.e. open burned) household waste bottom ash on ﬁred clay bricks. Between 0 to 50% (by weight) of open pit burned household waste bottom ash was mixed with clay to make bricks. The molded specimens were air-dried at room temperature for 24 h and then oven dried at 100 °C for another 24 h to remove the water. The raw bricks were fired in a muffle furnace to a designated tempera

Abstract:

Asbestos has been used massively for multiple applications for a long time. However, once the diseases related to this material were discovered, the European Union decided to intervene in the matter through a complex regulation that the member states had to transpose into their national legal system. In this sense, the regulation of the elimination of waste from architectural constructions and their demolition is of special interest. For this reason, the objective of this study focuses on finding out if this regulation could be improved to advance the permanent elimination, and if possible rec

Abstract:

The degree of heavy metals leaching from soils, sediments and waste depends on a number of physical and chemical factors. One of the key parameters governing the leaching process is the pH of the environment in which the waste is located. Laboratory studies aims to reflect the conditions prevailing in the environment, for example on landfill sites. The results of leaching of heavy metals (Zn, Cu, Pb, Ni, Cd, Cr) based on the pH of the eluent were presented in this article.

The use of glass waste, which by its nature cannot be recycled, might be a viable alternative in the manufacture of cements and concrete that is also economical and environmentally friendly. This alternative can reduce landfill areas with this inert residue but also limit the use of raw materials employed in the manufacture of cement and concrete and, consequently, contribute to minimize the environmental impact generated by this activity. In this research, the feasibility of using a limestone-type material treated with a binder manufactured with micronized glass powder and basic reagents, in

Abstract:

Abstract Landfill reclamation is a good solution to utilize the wasted land occupied by municipal solid waste dumpsites or landfill sites. This also offers a good means to recover valuable materials and form environmentally benign green refuse-derived fuel (RDF) for use in power production. However, due to the heterogenous composition of the wastes, it is crucial to homogenize and upgrade the waste hydrocarbon fuel properties. Torrefaction is a thermochemical process that utilizes low temperature and inert environment to drive off the moisture and volatile fractions present in wastes to form v
