The latest idea is to send drones up to scout out the best location to plant sorghum for biofuel production.
The project BioReGen is a very interesting plan developed on abandoned industrial estate in the north-east of England (Durham County). Basically, the project recovers polluted land by planting specific crops - in this case, crops intended for biofuels. The process is called biorecovery (see also MSU's project).
It seems that the biofuels industry continues to expand with the news this week that Brunei National Petroleum Co. is looking to partner with the Philippine National Oil Co. (PNOC) to build a biodiesel plant in the Philippines. Recently at an Asean Council on Petroleum meeting in Indonesia, PNOC officials revealed that they have received expressions of interest from several possible investors to pursue biofuels development.
