Researchers at the University of Maryland have developed a wood-based material that outperforms almost all other heat insulators and costs about $7 a metre to manufacture.
“Nanowood” is created by stripping away all the filler material in wood, leaving just the fibres. This is achieved by exposing wood to sodium hydroxide, sodium sulphite and hydrogen peroxide, all inexpensive chemicals. This strips out the cell walls, leaving the wood’s natural, parallel fibres, which create the high-performance insulation. A square metre of nanowood would cost about $7 to make.
Because is is made from wood – a renewable resource – nanowood is environmentally sustainable too.
Great to hear some positive environmental news from the cosmetics industry. L’Oréal USA has announced it plans to achieve carbon neutrality in 2019 for all 21 of its U.S. manufacturing and distribution facilities by using renewable natural gas (RNG). The company currently has 17 renewable energy installations across the country, including large on-site solar arrays in Arkansas Kentucky and wind turbines in Texas.
To achieve this L’Oréal USA is adding to its diversified energy portfolio with RNG purchased from a new processing facility in Kentucky. The company hopes a renewable energy production solution utilizing landfill gas (LFG) in Ashland that will eliminate the carbon equivalent of 1.8 million gallons of gasoline a year.
“Pride, Not Guilt Biggest Driver of Pro-Environmental Actions”
Just as I suspected. Finally the researchers have caught up with me. People respond better to pride than guilt. Guilt only works when you know your headmaster/ parents/ police force is standing behind the door keeping an eye on you.
