Volatile organic compounds (VOCs) are organic chemicals that have a high vapor pressure at ordinary room temperature. Their high vapor pressure results from a low boiling point, which causes large numbers of mole ...
A mineral is, broadly speaking, a solid chemical compound that occurs naturally in pure form.Minerals are most commonly associated with rocks due to the presence of minerals within rocks. These rocks may consist ...
Soils may become contaminated by the accumulation of heavy metals and metalloids through emissions from the rapidly expanding industrial areas, mine tailings, disposal of high metal wastes, leaded gasoline and paints, land application of fertilize ...
Mining is the extraction of valuable minerals or other geological materials from the Earth, usually from an ore body, lode, vein, seam, reef or placer deposit. These ...
A biorefinery is a facility that integrates biomass conversion processes and equipment to produce fuels, power, and value-added chemicals from biomass. Biorefinery is analogous to today's petroleum refinery, which produces ...

Liquefied petroleum gases (LPG) are a constituent of crude oil or the condensate of natural gas fields. They are the C3 and C4 hydrocarbons, propane and butane respectively, which have the property of being gases at normal ambient temperature but ...
Bioconversion, also known as biotransformation, is the conversion of organic materials, such as plant or animal waste, into usable products or energy sources by biological processes or agents, such as certain microorganisms. One exa ...
Microbial biosurfactants are extracellular compounds produced by microbes such as bacteria, fungi and actinomycetes when grown in culture medium containing hydrophobic/hydrophilic substrates. Biosurfactants are surface active molecules having hydr ...
Bioplastics are plastic materials produced from renewable biomass sources, such as vegetable fats and oils, corn starch, straw, woodchips, sawdust, recycled food waste, etc.Bioplastic can be m ...
Pollution is the introduction of contaminants into the environment that cause harm or discomfort to humans or other living organisms, or that damage the environment, which can come in the form of ...
Energy has played a critical role throughout human society's demographic, economic and social development. The availability and quality of various energy and material resources to a society is linked to the general trend of the settlement, gro ...
