This article is going to talk about types of solid waste materials qualify as a bio-renewable resource.

Agricultural Residues are the non-edible stalk type materials that stay after the harvest of the edible portions of the crops, like corn, wheat, grain, and sugar cane. Agricultural residues additionally consist of plant leaves, husks, some roots, and stems.

The residues of dedicated bioenergy non-food crops grown for their starches, sugars, or oils for the conversion into bio-ethanol and bio-lubricants. The advantage of agricultural residues is that they do not need the utilization of extra land space since they are grown along with the food crops.

Food processing Waste is the effluent wastes from a wide range of industrial processes ranging from breakfast and cereal bar makers to fresh and frozen vegetable manufacturers to alcohol breweries. These residues and wastes can be in the type of either dry solids or watery liquids. The fermentation of liquid wastes and oils from the food processor can turn out ethanol.

Municipal Solid Waste is the things that are thrown away in the garbage and trash and is collected by the trash bin men or sent to the recycling center. Municipal solid waste like particularly paper, cardboard, and discarded food merchandise, is a beautiful supply of endless biomass feedstock. However, not all municipal waste is appropriate as a biomass resource, particularly metallic and plastic waste.

Animal Waste from farms, ranches, slaughterhouses, fisheries, and dairies or any concentration of animals into big livestock farming facilities produces big amounts of manure and sewage sludge. Liquid waste, animal wastes, and additionally human waste from urban areas, provides a constant source of chemical energy and gases which could be converted into electrical power at these wastewater treatment plants. The treatment of animal waste produces flammable methane and biogas which can then be used for heating and transportation.

The management and disposal of solid waste have become one of the main issues we face nowadays. The rise within the volume of unwanted waste is one aspect of the present environmental crisis. Other than the problem in characterizing the waste material, due in part to its variable and complicated composition, several waste materials share a couple of common attributes, with the principal one being their low price.

Because of this, solid waste materials have little or no apparent economic value and can, therefore, be acquired for small more than their cost of transportation. In some cases, waste is considered a negative cost because of the ever-increasing cost of skip hire for solid waste disposal or the restrictions on the disposal of certain forms of wastes at landfill sites, several companies or households are only too happy to pay somebody to get rid of their waste as a bio-renewable resource for process.

Clearly, kinds of stuff that will be reprocessed into biomass feedstock to be used in an energy conversion process are therefore no longer classed as unwanted waste material with the demand for these new-found renewable biomass resources on the enhancing. As waste currently presents itself as an attractive bio-renewable resource, several currently demand payment for their waste. Then those companies or households that generate the waste currently view themselves as waste suppliers turning what was once a negative value into a positive profit.

However, as well as using waste materials as a biomass resource, dedicated energy crops are grown specifically as an energy source. These dedicated energy crops aren't solely greener and cleaner for solid waste materials, however, their use represents a closed and balanced carbon cycle with regards to atmospheric greenhouse emission.
