Sentences with phrase «biofuels crop wasted»

I have proposed that we develop the process of pyrolysis to be used on organic wastes to cut the reemitting of GHGs from the wastes that are basically a biofuels crop wasted that usurp no land or water from food production.

Not exact matches

If biofuels are to free us from rising prices at the pump and rising sea levelsthey must be produced from agricultural and urban wastes rather than corn, soy, and other food crops.

One of the major problems with biofuels that algae could solve is space, since algae can yield as much as 100 times more fuel per unit area than other so - called «second generation» biofuel crops (e.g. non-food crops or non-food waste parts of food crops).

Once harvested, these crops would get ferried by truck or train to power plants and other industrial facilities where, along with waste from food crops and timber harvests, they would be burned for heat or electricity, or converted to ethanol and other liquid biofuels.

Study author Catherine Bowyer says the next generation of biofuels, made from wastes or wood rather than crops, would have less impact on land use than biofuels made from crops, but «the policy is also not effectively stimulating advancements in biofuel technologies».

The amount of biomass available from corn and food crops is very small; for biofuels to have a large impact, we must harness energy from nonedible plants, also known as cellulosic biomass — wood and wood waste, agricultural waste, and energy crops.

No, the EU now gets more than 60 per cent of its renewable energy from biomass: some from crops grown to make liquid biofuels, but mostly from waste wood and felled trees.

Doing this with our organic wastes - biofuel crop, some energy is generated and we could greatly expand windmill generated electricity that has no GHG emissions and actually recycles some of the energy excess created by fossil fuels.

The best biofuel is still ethanol from corn but it has to be part of an integrated production facility which should include the following steps: cattle feed lot, feed all waste (distiller's dried solids) to the cattle, convert the cattle waste to methane to supply part of the energy source for the distillation, burn the dry crop waste to provide the remainder of the energy, irrigate the crops with the effluent from the methane digestor.

There's been a lot of talk lately about the food crisis, and particularly linking it to growing crops for biofuels (a highly inefficient process which seems to drive prices up, particularly in US policy), but Frances More Lappe argued in her books several years ago that there is, in fact, enough food on the planet to feed us all, but localized political troubles (grain rotting in Haitian ports), increasing desertification, food waste, and problems with global supply chains are better explanations for why so many go hungry.

Methane released from animals and their wastes can be reduced by altered diets and methane capture systems, and nitrous oxide production can be reduced by judicious fertilizer use27 and improved waste handling.24 In addition, if biofuel crops are grown sustainably, 28 they offer emissions reduction opportunities by substituting for fossil fuel - based energy (Ch.

Advanced biofuels can be derived from lignocellulosic feedstocks, such as agricultural waste (e.g., corn stover, wheat straw, rice hulls), agricultural processing byproducts (e.g., corn fiber or sugar cane bagasse), forestry and wood processing waste, the paper portion of municipal solid waste, or dedicated energy crops such as switchgrass.

Researchers continue to struggle to develop «second generation» biofuels that they hope will use enzymes to turn cellulose from wood and crop waste into ethanol.

Cellulosic ethanol proponents have pushed the idea of using farm waste as a way to boost biofuel production without impacting food crops, but such conversion may carry a hidden cost in areas with insufficient rainfall or lacking irrigation, warns a soil scientist from Washington State University.

Renewable, non-polluting fuels are: electricity (when generated by a clean source), biodiesel and cellulosic ethanol (when these biofuels are generated using «waste» material or from crops grown in a sustainable manner).

I, for one, have always been against turning food crops into biofuel right from the get - go, tho I've always thought ag wastes make good candidates, such as manure, which otherwise pollutes localities near industrial livestock farms.

re: 107 the problem is that it was to be marginal land use, interstitial crops and waste plant product that was to be used for biofuel.

-LSB-...] Tallow - waste biofuel is more ethical than other alternative fuels, since it does not displace food crops such as corn... ``

Biofuel A fuel derived from renewable, biological sources, including crops such as maize and sugar cane, and some forms of waste.

Since the waste product already exists, it means creating the pellets requires no resource - intensive crop watering, as must be done with other biofuels.
