The analysis of solid waste or incinerated residue for information regarding the chemical constituents involved the development and adoption of analytical methods. Methods were developed for the determination of nitro­ gen, carbon, hydrogen, protein, chemically decomposable organic and calorific values. The chemical composition of two types of residue and unburned solid waste was de­ termined u...

The effect of poultry waste application on physicochemical and biological properties of sandy clay loam soil was investigated on a 7m X 7m plot of land. Plot was divided into four portions and 7.5kg each of broiler, cockerel and layers waste was applied to plot A, B, and C in slurry form while plot D was used as control(no application) for eight weeks with two weeks interval. After the fourth a...

The disposal and dumping of toxic waste is a matter of growing concern in developing countries, including South Africa. Frequently these countries do not possess access to gas chromatography-high resolution mass spectrometry (GC-HRMS) for the determination of persistent organic pollutants (POPs). This publication describes an alternative approach to the investigation of toxic waste using compre...

This paper presents a general over view of the current municipal solid waste (MSW) management in Kolkata province, India. In order to characterize the solid waste stream in the Municipality of Kolkata, a long-term study was conducted over a 56-week period between the winter of 2010 and the winter of 2011. In this study, percentage of components and specific weight of the MSW, the composting par...

Rotary kilns are widely used for the thermal treatment of highly toxic waste. The waste (mostly organic compounds) is packed in barrels before it is fed in the kiln. Depending on the compound the heating inside the kiln leads to deflagrations of the barrels associated with an incomplete burnout. In this paper we present a new method to detect and track waste barrels in infrared image sequences ...

Human industrial activities, inevitably, generate industrial wastes, consisting of, inorganic and organic materials, discharged from factories, fisheries, poultries and food processing industries. Degrading or handling these wastes, as unused disposals, without acquiring any additional benefits has led to an idea to develop a suitable technology to utilize bio-organic wastes. Chicken feathers h...

High-quality bio-organic fertilizers (BIOs) cannot be produced without the addition of some proteins, while many waste proteins are haphazardly disposed, causing serious environmental pollution. In this study, several waste proteins were used as additives to assist with the reproduction of the functional microbe (Bacillus amyloliquefaciens SQR9) inoculated into matured composts to produce BIOs....

The biodegradation module of a simulation program for municipal solid waste landfills (MODUELO) was developed. The biodegradation module carries out the balance of organic material starting with the results of the hydrologic simulation and the waste composition. It simulates the biologic reactions of hydrolysis of solids and the gasification of the dissolved biodegradable material. The results ...

Background: Composting as a waste management technology is becoming more widespread. The purpose of this study was to assess the feasibility and to find the most effective composting process for the ratio of green waste, digested and dewatered sludge from Chonibieh wastewater treatment plant in the west region of Ahvaz. Methods: The composting time was 23 days and the evaluated parameters in th...

Waste-to-Energy (WTE) is a viable option for Municipal Solid Waste (MSW) management and a renewable energy source. MSW is a chronic problem in Saudi Arabia and more specifically in Saudi Urban areas. The MSW practices in KSA are simply done by collecting the waste and dumping it in open landfill sites. KSA is considering WTE as a potential renewable energy source that can contribute to electric...
