Almost any biomass can be briquetted. Biomass waste is the material derived from plants that use Photosynthesis to grow which include plant and animal material such as wood from forests, material left over from agricultural and forestry processes, and organic industrial, human and animal wastes. Biomass comes from a variety of sources which include:
- Wood from natural forests and woodlands
- Forestry plantations
- Forestry residues
- Agricultural residues such as straw, stover, cane trash and green agricultural wastes
- Agro-industrial wastes, such as sugarcane bagasse and rice husk
- Animal wastes
- Municipal solid wastes (MSW)
- Food processing wastes
Agro Waste or Briquetting:-
Agricultural waste can be described as all the organic materials which are produced as by-products from harvesting and processing of agricultural crops. These residues can be further categorized into primary residues and secondary residues. Agricultural residues, which are generated in the field at the time of harvest, are defined as primary or field based residues whereas those co-produced during processing are called secondary or processing based residues.
- Primary residues- Agricultural residues, which are generated in the field at the time of harvest, are defined as primary or field based residues paddy straw, sugarcane top, maize stalks, coconut empty bunches and frond, palm oil frond and bunches;
- Secondary residues-Agricultural residues, which is co-produced during processing are called secondary or processing based residues. Rice husk, bagasse, maize cob, coconut shell, coconut husk, coir dust, saw dust, palm oil shell, fiber and empty bunches, wastewater, black liquor.
Forest Waste Briquetting:-
Forest harvesting is a major source of biomass for energy. The largest source of energy from wood is the waste product from the pulp and paper industry called black liquor. Logging and processing operations generate vast amounts of biomass residues. Wood processing produces sawdust and a collection of bark, branches and leaves/needles. A paper mill, which consumes vast amount of electricity, utilizes the pulp residues to create energy for in-house usage. beside Pulp Waste from Paper mills Wood chips and shravings, Tree bark and twings, Saw dust bamboo leaves. Wild grasses. Shrubs Above raw material can be briquettes without using any binder. After making Briquettes from above materials it contains calorific value of 3500-4800 k.cal/kg.
