Biomasa i Agricultural Residues

Lignocellosic biomasa - such as corn stover, whead straw, forestry residues, and dedicate energy crops like chanches andmiscanthus - is abundant andd relatively low- coss. These materials consist primarily of cellulose, hemicellulose, and lignin, which can be broken down into sugars and aromatic compounds ditigh terchemical or biochemical conversion. However, their high oksygen content and structural experity require advanced prement and cataptec.

Mikroalgae andd macroalgae (seaweeds) have gained attention for their high lipid yields per acre and rapid growth rates. Algae can produce oils approppleable for hydroresurevaling into resultable diesel and sustainable aviation fuel (SAF), while the residual biomasa can be converted into biogas or biochar.
