In the US, Sustana leather is made from hides of sustainably managed cattle supplied by the Coleman ranch company in Colorado. Coleman cattle are raised humanely from birth without steroids, growth hormones and antibiotics. They are fed on pesticide-free feed and water and allowed to roam on pastureland that is managed on a rotational grazing system to reduce the impacts of overgrazing. Sustana hides are tanned by Cudahy Tanning, a family-owned, specialty leather producer in Wisconsin. Wool Small amounts of organic wool are available from New Zealand and Iceland.
Many countries still use strong pesticides for sheep dip.
Wool can also be used for non-fibre applications, such as with Clima Wool, a building insulation product. Secondary metals Recycled or 'secondary' metal is in principle an excellent idea. They are being used for bags, cutlery and plates, pens, clothing, credit cards, food packaging, agricultural films, teabags, coffee filters, diapers and napkins. It is also possible to make PLA from milk residues and even household waste. Even Barbie may go Bioplastic.
