Cattura del carbonio, riciclo, nuovi materiali, agritech: l’ingegneria che rimette la materia in circolo.
L’ecotech è l’ingegneria che rimette la materia in circolazione: catturare il carbonio invece di lasciarlo fuggire, riutilizzare ciò che si dava per perso, sostituire un materiale pesante con uno pulito. La rubrica segue le linee pilota di riciclo — pannelli solari, pale eoliche, plastiche —, la cattura e l’uso della CO₂, i cementi e gli acciai a basse emissioni, e l’agritech che produce di più con meno acqua e meno input.
Raccontiamo ciò che si misura: una resa di recupero, un costo alla tonnellata, una fabbrica che apre, un processo che passa dal laboratorio alla linea di produzione. Ogni articolo cita le sue fonti — spesso annunci industriali o pubblicazioni scientifiche che la stampa generalista non riprende — e distingue ciò che già funziona da ciò che resta un prototipo. È la materia del progresso, in senso letterale.
