A review on biomass: importance, chemistry, classification, and conversion

Biomass is currently the most widespread form of renewable energy and its exploitation is further increasing due to the concerns over the devastative impacts of fossil fuel consumption, i.e., climate change, global warming and their negative impacts on human health

Scholarcy highlights

  • Biomass is currently the most widespread form of renewable energy and its exploitation is further increasing due to the concerns over the devastative impacts of fossil fuel consumption, i.e., climate change, global warming and their negative impacts on human health
  • More generally, biomass is a combination of naturally derived materials, originating from plants such as shrubs, trees, algae, crops as well as all the materials composed of organic matrix except for plastics originating from petrochemical and fossil materials
  • Biochemical conversion processes allow the decomposition of biomass to available carbohydrates, which could be converted into liquid fuels and biogas, as well as different types of bio-products, using biological agents such as bacteria, enzymes, etc.
  • Replacement of fossil energy carriers with biomass-derived energy carriers could bring about positive impacts from multiple perspectives, i.e., economic, environmental, and health
  • Production of biomassderived energy could be achieved under any geographical conditions owing the large availability of biomass all over the world while it could simultaneously contribute to efficient management of various waste streams
  • An essential requirement of the dry biomass used is its moisture content, which should be less than 50%
  • Technological innovations to increase productivity and reduce costs are the main challenges to further expand the share of such renewable energy carriers
  • In order to provide an economic analysis of the different production technologies generating the main products from biomass, an assessment of the production cost, conversion efficiency, and size of the processing is presented
