After some reflection, the hype over biofuel has given way to criticism by environmentalists. The controversy revolves around the fact that many biofuels require use of land and crops that would otherwise be used for growing food, further inflating food costs and leading to more deforestation as farmers try to meet growing demand.
But, there are many other, more sustainable, ways to create biofuels. There is extensive research into using algae, waste materials, and many other alternative materials to create cleaner burning,more sustainable fuels that do not require the use of farm land or foodstuff.
Here at the Farm we drink a good ridiculous absurd amount of coffee and are avid recyclers, so we were exited to uncover new research that shows used coffee grounds can be used to create biofuel. WIN!
“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.” – Scientific Blogging
It is rumored that coffee ground biofuel even smells like coffee…mmmmmmmm!
The future energy picture will probably be a mixed bag, varying from region to region and country to country, customized to suit each areas individual needs and resources. Biofuels that make use of organic waste could be a very welcome development and play a big part in reducing carbon impact and moving us toward energy independence. Solutions like this are a great opportunity, especially for the foodservice industries who are always vigilant about waste. Imagine greening up your image and cutting your bottom line at the same time.
