The proposal also provides incentives for biofuels with no or low emissions from ILUC. The EC especially wants to encourage second- and third-generation biofuels that are produced from feedstock, such as algae, straw, and various types of waste. These don't create additional demands for land and will contribute proportionately more toward the target of 10 percent renewable energy in transport fuels.
One major study indicating problems with the environmental friendliness of biofuels was conducted recently by Empa, the Swiss Federal Institute of Technology's materials science and technology laboratory. It concluded that only a few are more sustainable than petroleum-based fuels.
In many cases, although agriculture-based feedstocks cause fewer greenhouse gas emissions, they lead to other problems, such as increasing soil acid or pollution from fertilizer. Although biofuels from ethanol tend to have a better ecobalance than oil-based fuels like palm or soybean oil, results in each case depend on manufacturing method and fuel technology.
The study points out that environment assessment methods have been refined and better developed during the same time period that second-generation biofuels have been created, along with more innovative production methods.
With that cumulative perspective, it shouldn't be a surprise that first-generation food crop-based biofuels aren't such a great idea, because they not only affect food and feed crops, but may also be harmful in other ways. Other plant-based biofuel feedstocks, such as algae, may prove to be a lot less impactful on the environment.
Dave, thanks for the explanation, it makes a lot of sense. Sounds like there are multiple ways metal can be non-recovered. That 10% figure is higher than I would have guessed. I'll be very interested to see the results of the interview, assuming you can get it.
A make-your-own Star Wars Sith Lightsaber hilt is heftier and better-looking than most others out there, according to its maker, Sean Charlesworth. You can 3D print it from free source files, and there's even a hardware kit available -- not free -- so you can build one just in time for Halloween.
Some next-generation bio-based materials are superior in performance to their petro-based counterparts, but also face some commercial challenges. This is especially true of certain biopolymers, adhesives, coatings, and advanced materials.
Cars and other vehicles, as well as electronics and medical devices, continue to lead the use cases for the new plastics products we've been seeing, as engineers design products for tougher environments.
LeMond Composites, founded by three-time Tour de France cycling champion Greg LeMond, is the first to license a new carbon fiber production method invented by Oak Ridge National Laboratory (ORNL) that's faster, cheaper, and greener.
This month will mark the launch of the SpeedFoiler, a super-fast, ultra-lightweight foiling catamaran that can fly short distances over water faster than other foiling designs, in part because of its carbon composite materials.
