Kenneth A. Smith wTe Corporation Bedford, Massachusetts The SEMASS waste-to-energy facility has employed the straightforward "Shred Burn" approach to Refuse Derived Fuel (RDF) production. The relatively trouble-free start-up seems to indicate that the design­ ers have incorporated the industry learning experience of the past 10 years. In this discussion, questions are raised relative to local p...

Waste plastics are harmful, toxic, and non-biodegradable. Environmental impacts of waste plastics are raised concern about all over the world for safe and friendly environment. Due to dense population and environmental effects of the major city in the world dumping, incineration and land filling are faced difficulties and challenges. At this circumstances vast of waste plastics are remained vul...

Refuse-derived fuel (RDF) is a mixed industrial waste, which often contains combustible materials (cellulose, polymers, rubber, biomass, etc.). The RDF waste precursor subjected to thermo-oxidation treatment at 300℃, followed by carbonizations 600℃, and high temperature hydropyrolysis 800℃. obtained nanoporous carbon material was detailed characterization low nitrogen sorption, elemental analys...

Radiocarbon samples taken over Mexico City and the surrounding region during the MILAGRO field campaign in March 2006 exhibited an unexpected distribution: (1) relatively few samples (23%) were below the North American free tropospheric background value (57±2‰) despite the fossil fuel emissions from one of the world’s most highly polluted environments; and (2) frequent enrichment well above the...

purpose: the purpose of this paper is to evaluate to what extent the construction of common and individual biogas plants can answer the fuel needs of rural people or families. methodology: the present study with descriptive - analytical method, examines the fuel needs of the rural people and its supply by biogas from livestock waste. findings: the primary outcome of the proportion of rural popu...

Abstract: The Thermoselect process is a completely new solid waste treatment process which achieves pollution-free recycling of municipal solid waste and industrial waste by a high temperature gasification and reforming process. The process effectively recovers fuel gas from waste and recycles metal and other byproducts as resources. A stable gas engine power generation system using purified sy...

BACKGROUND AND OBJECTIVES: Urban intensity and activities produce a large amount of biodegradable municipal solid waste. Therefore, biodrying processing was adopted to ensure the conversion into Refuse Derived Fuel and greenhouse gases. METHODS: This study was performed at a greenhouse, using six biodrying reactors made from acrylic material, and equipped...

The production of fatty acid methyl esters (FAMEs) from waste activated bleaching earth (ABE) discarded by the crude oil refining industry using lipase from Candida cylindracea was investigated in a 50-L pilot plant. Diesel oil or kerosene was used as an organic solvent for the transesterification of triglycerides embedded in the waste ABE. When 1% (w/w) lipase was added to waste ABE, the FAME ...
