MBL begins first test of tropical seaweed farming for biofuels production

Green Car Congress

A team of researchers led by Loretta Roberson, associate scientist at the Marine Biological Laboratory, Woods Hole, has installed the first seaweed farm in Puerto Rico and US tropical waters. Puerto Rico has stable warm temperatures and ample sunlight year-round, as well as a wide range of exposure to prevailing winds and waves.

Selective confinement of rare-earth-metal hydrates in host molecules

Green Car Congress

Rare-earth metals are indispensable for many technical products, from smartphones, laptops, batteries, electromotors, and wind turbines, to catalysts. They are everywhere in the environment but are highly dispersed and bound in minerals (“earths”); large deposits are rare. Their states of hydration are different and may change.

Study: Energy sorghum may combine best of annual, perennial bioenergy crops

Green Car Congress

Maize and other annual crops are easier to manage with traditional farming, but they are tougher on the environment. The researchers conducted ecosystem-scale comparisons of carbon, nitrogen, water, and energy fluxes of Sorghum bicolor with maize and Miscanthus x. Energy sorghum falls somewhere in between.

Study Finds Crop Residue Removal for Biofuels Adversely Impact Soil and Environment; Dedicated Energy Crops Can Provide Benefits

Green Car Congress

Available data indicate that herbaceous and woody plants can improve soil characteristics, reduce soil water and wind erosion, filter pollutants in runoff, sequester soil organic carbon, reduce net emissions of greenhouse gases, and improve wildlife habitat and diversity.
