In our effort to keep you informed on the latest developments and news in sustainability, hazardous waste management, and solvent recycling, we’re sharing the articles below from March and April, 2015. Take a look at our picks for top stories over the last couple of months.
WEST LAFAYETTE, Ind. – Researchers have shown how to convert waste packing peanuts into high-performance carbon electrodes for rechargeable lithium-ion batteries that outperform conventional graphite electrodes, representing an environmentally friendly approach to reuse the waste.
Batteries have two electrodes, called an anode and a cathode. The anodes in most of today’s lithium-ion batteries are made of graphite. Lithium ions are contained in a liquid called an electrolyte, and these ions are stored in the anode during recharging. Now, researchers at Purdue University have shown how to manufacture carbon-nanoparticle and microsheet anodes from polystyrene and starch-based packing peanuts, respectively.
ACS Meeting News: From sewage sludge to junkyards, scientists explore new ways to mine metals | By
Metals are ubiquitous in our lives. There are the metal objects we can see—paper clips, kitchen utensils, electronics, cars or bicycles, wires and pipes, lightbulbs, hammers and shovels. Most of those are not recycled, although they could be.
But then there are personal care products, glass, paint, and tires—things that contain metals but for which there is no ready way to recover the metal, or the metal is abraded and gets scattered in the environment.
Cargill President and Chief Executive Officer Dave MacLennan declared that sustainability is the ‘new normal” at this week’s Financial Times Commodities Global Summit. He called on the commodities industries to embrace transparency and help define what sustainable supply chains could and should look like in a world where 9-plus billion people will need to be fed.
This year Cargill celebrates its 150th anniversary, and like everyone else in the commodities industry, we learned early that markets are always changing, there is always a “new normal” on the horizon, and if we are going to survive and thrive, we need to continually change and adapt.
