Les mots sont importants (lmsi.net) Corncob. Young ears, also called baby corn, can be consumed raw, but as the plant matures the cob becomes tougher until only the kernels are edible.
When harvesting corn the corncob may be collected as part of the ear or may be left as part of the corn stover in the field. The innermost part of the cob is white and has a consistency similar to foam plastic. Uses[edit] Corncobs find use in the following applications: Corncobs are also commonly used as bedding for rodents used as subjects in research experiments, usually supplemented with other types of bedding like cotton fiber intended to reduce respiratory problems blamed in turn on all-corncob bedding and bacterial growth.

Researchers in Nevada are reporting that waste coffee grounds can provide a cheap, abundant, and environmentally friendly source of biodiesel fuel for powering cars and trucks.
In the new study, Mano Misra, Susanta Mohapatra, and Narasimharao Kondamudi note that the major barrier to wider use of biodiesel fuel is lack of a low-cost, high quality source, or feedstock, for producing that new energy source. Spent coffee grounds contain between 11 and 20 percent oil by weight. That's about as much as traditional biodiesel feedstocks such as rapeseed, palm, and soybean oil.
Growers produce more than 16 billion pounds of coffee around the world each year. The used or "spent" grounds remaining from production of espresso, cappuccino, and plain old-fashioned cups of java, often wind up in the trash or find use as soil conditioner. To verify it, the scientists collected spent coffee grounds from a multinational coffeehouse chain and separated the oil.
Biodiesel is a growing market. Applications : Biomass and Sewage Sludge -Biogreen® Usage of Sewage Sludge becomes a huge problem for environment !
Landfilling has become more and more difficult due to pollution of the sewage sludge, odors, heavy metal and pathogens. Disposal has become dificult and has been even banned in somes countries. Also, incineration is a non popular and very costy solution for sewage sludge treatment. Why pyrolysis sewage sludge with Biogreen® may be a good alternative: Biomass. Sugarcane plantation in Brazil (State of São Paulo).
Cane is used for biomass energy. A cogeneration plant in Metz, France. The station uses waste wood biomass as an energy source, and provides electricity and heat for 30,000 dwellings. Biomass is biological material derived from living, or recently living organisms. It most often refers to plants or plant-based materials which are specifically called lignocellulosic biomass.[1] As an energy source, biomass can either be used directly via combustion to produce heat, or indirectly after converting it to various forms of biofuel. Wood remains the largest biomass energy source to date;[2] examples include forest residues (such as dead trees, branches and tree stumps), yard clippings, wood chips and even municipal solid waste.
Plant energy is produced by crops specifically grown for use as fuel that offer high biomass output per hectare with low input energy. The biomass used for electricity generation varies by region. Renewable heat. Renewable heat is an application of renewable energy and it refers to the renewable generation of heat, rather than electrical power (e.g. replacing a fossil fuel boiler using concentrating solar thermal to feed radiators).
Many colder countries consume more energy for heating than electrical power. For example, in 2005 the United Kingdom consumed 354 TWh[1] of electric power, but had a heat requirement of 907 TWh, the majority of which (81%) was met using gas. The residential sector alone consumed a massive 550 TWh of energy for heating, mainly in the form of gas. Almost half of the final energy consumed in the UK (49%) was in the form of heat, of which 70% was used by households and in commercial and public buildings.
Households used heat for mainly for space heating (69%) and heating water.[2] The relative competitiveness of renewable electricity and renewable heat depends on a nation's approach to energy and environment policy. Electric olives power Europe. By Jerry W.
Kram Posted Aug. 20, 2007, at 9:24 a.m. CDT The olive tree has been central to the cuisine-and some would say even the soul-of southern Europe for millennia. This venerable renewable resource is again finding a role in the new century as a source of biomass energy. Olives are crushed, and the oil is mechanically pressed out, leaving wet olive cake. The use of olive residue as a biomass fuel has attracted attention from across the European Union. Pellet fuel. Wood pellets.
Pellet fuels are heating fuels made from compressed biomass. Wood pellets are the most common type. A form of wood fuel, wood pellets are generally made from compacted sawdust or other wastes from sawmilling and other wood products manufacture,.[1] Other woody biomass sources include palm kernel shell, coconut shell, and whole-tree removal or tree tops and branches leftover after logging and which otherwise help replenish soil nutrients.[2] As well grasses can also be pelletized, creating grass pellets.
Pellets are manufactured in several types and grades as fuels for electric power plants, homes, and other applications in between.[3] Pellets are extremely dense and can be produced with a low moisture content (below 10%) that allows them to be burned with a very high combustion efficiency.[4] Further, their regular geometry and small size allow automatic feeding with very fine calibration.
