Several research programs investigated energy crops (aquatic and marine plants, grasses, and woods) and municipal solid wastes (MSW) coupled with anaerobic digestion for generation of renewable substitute natural gas. These programs integrated research on crop production and harvesting, collection of municipal solid wastes, conversion of these feedstocks to methane by anaerobic digestion, and s...

In past two decades waste management has become one of the most important public concern in developing countries. Hospital waste management has become a critical issue as it poses potential health risks and damage to environment. All those wastes which are generated in hospitals or during health care activities carries a higher risk for infection and injury than any other wastes. In the process...

This paper describes the determination of fatty acid composition of coffee, citrus and rum distillery wastes using reversed-phase high-performance liquid chromatography (RP-HPLC). Lipid extracts of the waste samples are derivatized with phenacyl bromide and their phenacyl esters are separated on a C8 reversed-phase column by using continuous gradient elution with water and acetonitrile. The pre...

The Thermogravimetric Analysis (TGA) techniques and concretely the study of the burning profile provide information that can be used to estimate the behaviour of the combustion of carbonous materials. Commonly, these techniques have been used for the study of carbons, but are also interesting for the analysis of biomass wastes, due to the different species present on the wastes affect directly ...

The winery and distillery industry generates an increasing amount of wastes, whose management and disposal constitute an environmental concern due to their seasonal character and some polluting characteristics. The main solid by-products and residues generated are grape stalk, grape pomace or marc, wine lee, exhausted grape marc and winery sludge, while the main effluents are winery wastewater ...

more garbage than any other nationover 160 million tons of garbage each year or more than 1,200 pounds per person. EPA expects this to increase to more than 2,300 pounds of garbage per person each year within the next 1 2 years. Whether it is recycled, buried or burned, the fate of this refuse has major impacts on public health, the environment and the economy. United States citizens generate W...

Background: The production of waste pollutants has become a major problem for many food and oil industries. However, oil wastes can provide alternative substrates for industry, which could help to solve environmental pollution problems. Furthermore, oil wastes can be used as substrates to produce unsaturated fatty acids, which are important for health. Objectives: The production of fatty acids ...
