Explainers, teardowns, and myth-busting on waste management systems and green engineering.
Hydrothermal carbonisation, gasification, energy recovery and phosphorus capture in a single automated plant near Treviso. The integration is the novelty — and the performance data is absent.
Four companies, six steps, and one link where the recycled content is attributed rather than physically traced. The pyrolysis is real. The loop is partly bookkeeping.
Aduro says its water-based chemistry converts waste plastic and heavy oil at lower temperatures than pyrolysis. Even if that holds, the output is still a feedstock that a refinery has to finish.
A startup claims up to 90% iron recovery from steel grinding sludge, a saleable coagulant, hydrogen as a by-product and a negative carbon figure. Almost none of the process detail behind those numbers has been published.
