Plastics remain the bane of many environmentalists, but aspiring venture capitalists seem to see polymers in a different light. Two of the top four finishers in this year’s Rice University Business Plan Competition focus on plastics. The winners get star treatment in the current issue of Fortune Magazine in a section headlined “Venture”.
The first place finisher is a new pharmaceutical and number two is an Internet tool for human authentication. And at number three is a project called PK Clean from two students at the Massachusetts Institute of Technology. Their intriguing idea? Conversion of plastic waste into diesel fuel. That should stop all the trash talk about plastics.
At the fourth spot is a project called cyclewood Plastics from a student team at the University of Arkansas. These students have developed a marketing plan for a biodegradable plastic bag made from a byproduct of paper production. OK. That one sounds like a pretty well tried-and tested idea. Many companies are now selling biodegradable plastic bags from a variety or renewable feedstocks. The one edge for cyclewood is use of a waste byproduct in a technology developed at the University of Minnesota. And who knows–maybe their bags will degrade faster than the competition!
Dealing with plastic bag disposal has been the bane of the retail existence for a long time. In retail, we had seen recyclable bags in the past, but they would stick together causing significant waste. The new generation seems to have better success but do not do well in hot environments or storage.
Producing high-quality end-production metal parts with additive manufacturing for applications like aerospace and medical requires very tightly controlled processes and materials. New standards and guidelines for machines and processes, materials, and printed parts are underway from bodies such as ASTM International.
Although plastics make up only about 11% of all US municipal solid waste, many are actually more energy-dense than coal. Converting these non-recycled plastics into energy with existing technologies could reduce US coal consumption, as well as boost domestic energy reserves, says a new study.
This year's Dupont-sponsored WardsAuto survey of automotive designers and other engineers shows lightweighting dominates the discussion. But which materials will help them meet the 2025 CAFE standards are not entirely clear.
Artificially created metamaterials are already appearing in niche applications like electronics, communications, and defense, says a new report from Lux Research. How quickly they become mainstream depends on cost-effective manufacturing methods, which will include additive manufacturing.
