Alternative Bioenergy Raw Material in Thailand
Sugarcane is one of a most a sustainable biofuel feedstock. Thailand have 8.46 million Rai (1Ha=6.25 Rai) of sugarcane field, have yield about 99.3 million ton of sugarcane which can be produced about 9.6 million ton of sugar per year. The sugar export volume about 6.6 million ton per year that makes Thailand is a second largest exporter of Sugar in the world after Brazil (The Office of sugar cane and sugar, 2011).
After the sugarcane has been harvested the tops and green leaves, containing some 30% of the energy available in the plant, remain in the field as a ‘trash blanket’. Farmers are allowing approximately a quarter of the trash to be gathered as biomass feedstock.
Napier
(Pennisetum purpureum and related hybrids of P.purpureum and P.glaucum or P.americanum)
The crop is a tall perennial plant, growing to 2 – 5mt tall, rarely up to 7.5 mt. Some of the higher DM yields reported are as high as 76 ovens dried tons per hectare per year. Pakchong 2 high up to 5 mt. BEST is the professional in Napier grass large plantations in South East Asia and can provide several services to optimize harvesting focusing to serve bioenergy business.
By the way several limiting factors regarding bioenergy crops harvesting operations and logistics need to be addressed and our company has a strong participation in the most advancement methods to reduce costs of delivered-biomass.

Bioenergy is a form of renewable energy and comes from materials derived from biological sources including plants, animals and their byproducts. That is, bioenergy is a kind of replenishable source of power, heat, and liquid and gas fuels rather than non-renewable fossil energy sources such coal, natural gas and petroleum.
The majority of biomass for bioenergy comes from three sources: forests, agriculture, and waste. For Southeast Asia, which is the agriculture area of the world, usually produce bioenergy from crops like Napier, Sugar Cane and Rice Husks.
Biomass is fuel that is developed from organic materials, a renewable and sustainable source of energy used to create electricity or other forms of power.
To make use of the energy available in biomass it is necessary to utilize technology to either release the energy directly, as in burning of biomass materials for heat, or to transform it into other forms such as solid or liquid fuel. There are three types of conversion technologies currently available, each appropriate for specific biomass types and specific energy products: thermal, chemical and biochemical
Biogas is a gas that occurs naturally from the fermentation of biodegradable under oxygen-free (anaerobic. digestion) typically refers to methane.
Biogas is generated through the process of anaerobic digestion or the fermentation of biodegradable materials such as biomass, manure, sewage, municipal waste, rubbish dumps, septic tanks, green waste and energy crops. In South East Asia, commonly use agricultural waste as a material. This type of biogas comprises primarily methane and carbon dioxide. The actual composition of biogas will vary depending upon the origin of the anaerobic digestion process – the feedstock.
