Estimation of the future technical potential of biomass as an energy source is dependent on assumptions with respect to land availability and productivity as well as conversion technologies. With the emergence of energy crops as the major source of biomass fuel, land use conflicts, especially in relation to food production, may arise. However, with efficient agricultural practices, plantations and crops could supply a large proportion of energy needs, with residues playing a smaller role without compromising food production or further intensifying agricultural practices.

The quantification of the actual reduction in green house gases sourcess emissions resulting from the substitution of fossil fuels with energy from waste biomass requires a complete lifecycle assessment (LCA). A systematic framework for estimating the net Green House Gases emissions from bioenergy systems and comparing them against the fossil fuel reference system that it would replace has been developed. The major considerations of the life cycle assessment approach to quantifying the greenhouse impacts of bioenergy are as follows: (more…)

Another large source of renewable carbon supplies is waste biomass. It consists of a wide range of materials and includes municipal solid wastes (MSW), municipal biosolids (sewage), industrial wastes, animal manures, agricultural crop and forestry residues, landscaping and tree clippings and trash, and dead biomass that results from nature’s life cycles. Several of these wastes can cause serious health or environmental problems if they are not disposed of properly. Some wastes such as MSW can be considered to be a source of recyclables such as metals and glass in addition to energy. Thus, waste biomass is a potential energy resource in the same manner as virgin biomass. (more…)

The most widespread and practical process for capture solar radiation as organic fuels is the growth of virgin biomass. Extremely large quantities of carbon are fixed each year in the form of terrestrial and aquatic biomass. (more…)

Over the last decade, the number of countries researching the potential of biomass and bioenergy for energy services rose rapidly. This contributed to the biomass as solid and liquid fuels, an interesting and promising option among renewable energy sources available. This includes solid waste and biomass, which comprises of charcoal, firewood, energy crops and forestry and agricultural residues to produce heat and electricity, (more…)

The convention aims not only at stabilizing CO2 emissions in developed countries but also at ultimately reducing man-made CO2 emissions globally so as to stabilize the global climate. Environmental degradation cannot be singled out as an independent matter among various global issues. (more…)

Advances in biomass feedstock production are extremely important. These advances have the potential for reducing the final cost of biofuels, power, and products. In addition, advances will allow the production of plants, trees, and residues with characteristics increasingly well suited for feedstocks. For example, genetically engineered plants feedstocks may allow higher yields of usable biomass per acre for fuel and other uses. New methods in erosion control, fertilization, and pre-processing can result in (more…)
