When dealing with complex matrices such as wastewater treatment plant (WWTP) sludge or animal manure, usual MRM quantification may lack enough sensitivity or accuracy due to the presence of numerous interfering compounds co-extracted from the matrix. To circumvent the sensitivity and specificity loss,...
How is biogas produced? Biogas is produced when microbial organic matter degrades in anaerobic conditions. It can be harvested from any number of places, such as landfill sites, waste water plants and even breweries. Generally made using sludge or animal manures rich in carbohydrates,...

The combustion of these fuels is responsible for 75 percent of of carbon dioxide emissions since the end of the 20th century. Fossil fuels were formed when prehistoric plants and animals perished and, over a period of millions of years, were buried and crushed under layers of rock. Mainly as...
On the other hand, sewage sludge, animal fat, and animal manure are the major constituents of non-lignocellulosic biomass, rich in protein and fatty acids with less lignin, cellulose, and hemicellulose. Although the term is usually reserved for transport fuels derived from biomass, its wider ...

Monoculture, in agriculture, the practice of growing a single crop on a given acreage. While monoculture crops are sometimes rotated year to year, continuous monoculture, or mono-cropping, in which the same crop is grown year after year, has become one o
of disease outbreaks and feed efficiency, and hence, additives such as amino acids,enzymes, probiotics, and vitamins have been introduced to enhance the quality and nutrition of animal feed. Regulations on sustainable livestock farming and reducing antibiotic use are also driving the use of natural ...
