Wood Pellets	15-18	8-12	0.5-1.0
Straw	12-15	15-20	5-10
Miscanthus	14-16	10-15	2-5
Food Waste	8-12	60-70	3-8

The table above provides a general overview of the properties of common biomass feedstocks. These values can vary based on species, growing conditions, and processing methods. The development of preprocessing technologies, such as torrefaction (a thermal treatment that improves the energy density and handling characteristics of biomass), is also gaining traction. These innovations aim to overcome some of the limitations associated with certain feedstocks and broaden the range of viable biomass energy options.

Biomass Conversion Technologies: A Comparative Analysis

Several distinct technologies can be employed to convert biomass into usable energy.
