“Feedstock” is the material that is burned to create biochar.

Woody biomass

Feedstock includes materials derived from trees and shrubs, such as wood chips, sawdust, bark, and branches. These feedstocks are commonly used in biochar production due to their high carbon content, availability, and potential for sustainable sourcing from forestry operations, tree trimmings, or wood processing industries. Similarly, Forestry residues generated from forestry operations, such as tree branches, bark, and forest thinnings, can be utilized as feedstocks for biochar production. These residues are often available as a byproduct of sustainable forest management practices or as a result of wildfire mitigation efforts.

Agricultural Residues

Agricultural residues offer a significant feedstock source for biochar production. Crop residues, such as corn stalks, rice husks, wheat straw, and sugarcane bagasse, can be utilized. These residues are typically byproducts of agricultural activities and can provide a renewable and abundant source of feedstock.

Construction & Demolition Waste

Construction and demolition (C&D) waste includes materials from building construction, renovation, and demolition activities. This waste stream often consists of wood scraps, lumber, plywood, drywall, and other organic materials. These materials can be processed and used as feedstocks for biochar production.

Animal Manure

Animal manure, including poultry litter, cow dung, and swine waste, can be used as a feedstock for biochar production. These organic materials contain high levels of nutrients and carbon, making them suitable for biochar production. Utilizing animal manure as a feedstock can also address waste management concerns and provide an additional value-added product.

Organic Waste

Various forms of organic waste can serve as feedstocks for biochar production. This includes food waste, yard waste, crop residues, and other organic materials from municipal, industrial, or agricultural sources. Utilizing organic waste as a feedstock can help divert it from landfills, reducing greenhouse gas emissions and providing a sustainable source for biochar production.

It's important to consider the specific characteristics, availability, and sustainability aspects of different feedstock sources when selecting the appropriate feedstock for biochar production.

Local availability, logistical considerations, and environmental impacts are all taken into account to ensure responsible and sustainable sourcing practices.
