Pulp and paper waste is the big new headliner as a feedstock for bioplastics. Corn was the big early play, but that has changed. The latest news: CSM subsidiary Purac said it has signed a contract to participate in a consortium that will develop a process to produce feedstock from cellulosic waste derived from the pulp and paper industry for the production of lactic acid. The other partners in the program are Crown Van Gelder N.V., a paper-producing company, and Bumaga B.V., a development center in the paper and board industry. The project is partly funded by the Dutch Ministries of Economic Affairs and Agriculture, Nature and Food Quality. The Dutch government has been a major supporter of bioplastics, and one of the other major players is DSM.
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.
