Captura de carbono, reciclagem, novos materiais, agritech: a engenharia que volta a pôr a matéria em circulação.
A ecotech é a engenharia que devolve a matéria à circulação: capturar o carbono em vez de o deixar fugir, reutilizar o que se dava por perdido, substituir um material pesado por um material limpo. A secção acompanha as linhas-piloto de reciclagem — painéis solares, pás eólicas, plásticos —, a captura e o uso do CO₂, os cimentos e aços de baixo carbono, e a agritech que produz mais com menos água e menos fatores de produção.
Contamos o que se mede: um rendimento de recuperação, um custo por tonelada, uma fábrica que abre, um processo que passa do laboratório à linha de produção. Cada artigo cita as suas fontes — muitas vezes anúncios industriais ou publicações científicas que a imprensa generalista não retoma — e distingue o que já funciona do que continua a ser um protótipo. É a matéria do progresso, no sentido literal.
