Restaurant grease is highly prized, because it can be used to create biofuel. Businesses that used to charge to pick up grease sometimes now pay for it instead – if it’s still there and hasn’t been stolen by grease rustlers, that is.
“You can pull in and drive off in five minutes. It can be $500 a night, $2,500 a week,” said Carrillo-Miranda, 37, a beefy man in a black T-shirt and jean shorts. “Even if your truck gets impounded, that’s $500. You’re still ahead $2,000 for the week.”
Interestingly, many legit grease haulers say they got started by stealing grease. There is a technology war going on too. Storage barrels are getting harder to break into, locks are stronger, and video cameras can record thefts.
Salt-tolerant desert plants, halophytes, can be grown on non-arable land using seawater, and processed to create biofuel. Wow. Even better, this is just one part of a process that grows fish and shrimp and mangrove biomass. This astonishing process is being developed by the Sustainable Bioenergy Research Consortium in Abu Dhabi.
Spanish company All-gas is converting wastewater to algae-based biofuel. This has never been done before. They hope to produce enough to power ten garbage trucks for a year by 2015. Let’s hope one day this can be done on a commercial scale.
Sweden extracts pyrolysis oil from wood to create synthetic fuel that now powers much of the country. Amazing, Sweden’s forest stock has increased despite the use of wood for biofuel.
Forest residue is the leading bioenergy source in Sweden, and bioenergy is the nation’s leading energy source. Since the 1970s when 70-80 percent of Sweden’s energy mix came from imported oil, the country has transformed its energy system to the point where oil is almost entirely a transport fuel, while bioenergy is used in district heating, industry and electricity production.
The Biobot converts waste cooking oil into biodiesel that you can pour in your gas tank. It’s small, efficient, is designed for home use, and stores 20 liters of biofuel. The process is fairly involved and requires monitoring. However, rather than dumping cooking grease now you can power a car with it.
