Biomass Effective use of biomass as a renewable energy source will require both large sources of biomaterial and large capacities for biorefining. These quotations are taken from the 60 page U.S. Depatment of Energy publication titled The Technical Feasibility of a Billion-Ton Annual Supply of Biomass Feedstock The purpose of this report is to assess whether the land resources of the United States have the potential to produce a sustainable supply of biomass that can displace 30 percent of the country's current petroleum consumption.
"Biomass is already making key energy contributions in the United States... Biomass currently supplies over 3 percent of the total energy consumption in the United States - mostly through industrial heat and steam production by the pulp and paper industry and electrical generation with forest industry residues and municipal solid waste (MSW). ...biomass is particularly attractive because it is the only current renewable source of liquid transportation fuel."
Efforts to discover multiple sources of biomass have lead to closer study of what may otherwise be treated as watse. The tree diagrams are an example. Additionally, planning for more complete reuse of construction and furniture waste is encouraging.
"In the manufacture of paper products, wood is converted into fiber using a variety of chemical
and mechanical pulping process technologies."
"Pulp and paper facilities combust black liquor in recovery boilers to produce energy (i.e., steam),
and, more importantly, to recover the valuable chemicals present in the liquor."
"The pulp and paper industry utilizes enough black liquor, bark, and other wood residues to meet
nearly 60 percent of its energy requirements. Currently, the forest products industry along with DOE
are looking at black liquor gasification to convert pulping liquors and other biomass into gases that
can be combusted much more efficiently."
"There are two principal sources of urban wood residues: MSW and construction and demolition debris.
MSW consists of a variety of items ranging from organic food scraps to discarded
furniture and appliances."
"Wood and yard and tree trimmings are the two sources within this residue stream that are
potentially recoverable for bioenergy and biobased product applications. The wood component includes
discarded furniture, pallets, containers, packaging materials, lumber scraps (other than new construction
and demolition), and wood residuals from manufacturing."
"The other principal source of urban wood residue is construction and demolition debris. These
materials are considered separately from MSW since they come from much different sources. These
debris materials are correlated with economic activity (e.g., housing starts), population, demolition
activity, and the extent of recycling and reuse programs."
