Os pneus verdes estão chegando, isto é, os ambientalmente corretos. A Goodyear e a Michelin uniram-se com empresas do setor de biotecnologia para desenvolver matérias-primas para pneus que fossem totalmente renováveis.
Hoje os pneus são produzidos, na grande maioria, a partir do petróleo – são gastos aproximadamente 30 litros de petróleo por pneu médio, o que torna a união entre estas grandes empresas um fato extremamente interessante. &nbsp;
Os primeiros protótipos dos “bio-pneus” já estão prontos e em testes, embora as empresas informem que este processo levará de 3 a 5 anos para que cheguem os primeiros pneus ao consumidor final.
A empresa especializada em biotecnologia, Genencor, desenvolveu micróbios capazes de quebrar o açúcar transformando-o em isopreno, hoje um derivado de petróleo.
Contudo, esta não é uma boa notícia para o mercado interno de etanol, que é derivado da cana-de-açúcar, diferentemente de outros países que o produzem a partir do milho. (Retirada do Site Inovação Tecnológica)
