Pyrolysis of agricultural waste to produce fuel gas involves formation of tars as noxious by-products. In this paper the qualitative analysis of tars formed during pyrolysis of rice husks is presented, based on identification by gas chromatography-mass spectrometry and interpolation of retention times on a polyaromatic hydrocarbon index scale. The influence of some reaction parameters on produc...

Given a base design with quantitative factors and a primary linear regression to each of the treatments, we may adjust secondary regressions of linear combinations of the adjusted coefficients on the primary regressions on the factor levels, thus obtaining a biregressional model. A biregressional design was established for a set of treatments, defined from quantitative factors and a linear regr...

The intensification of municipal-solid-waste (MSW) production, energy usage, and the curb landfill have developed need for our society to use MSW under vision a waste-to-energy (WTE) approach eradicating as well address issues across world. WTE alteration is an environment-friendly way disposing MSW. This study examines usage plastic, wood, paper RDF production. solitary yields, whose dependabi...

The management of discarded treated wood products upon disposal is one of the many factors that should be considered when evaluating a new wood preservative or when comparing wood preservatives as part of a life cycle assessment. Future environmental ramifications of disposal, as well as regulatory requirements and costs, must be assessed and weighed. This paper presents an overview of the fact...

This review presents the summary of new studies on pyrolysis of biomass to produce fuels and chemical feedstocks. A number of biomass species, varying from woody and herbaceous biomass to municipal solid waste, food processing residues and industrial wastes, were subjected to different pyrolysis conditions to obtain liquid, gas and solid products. The results of various biomass pyrolysis invest...

How arborists view the issue of “waste wood” is changing. The number of landfills has been steadily shrinking, while tipping fees at the remaining facilities are rising continually. Disposing of waste wood was once merely a time and labor factor, but now carries with it considerably more expense. Many arborists have adjusted to the higher cost of handling waste wood by looking for value-added m...
