Estaleiro Rio Grande is turning its focus to wood chips under its financial restructuring, although shiprepair will also be in the mix.

Owner Ecovix is essentially turning the former maker of Petrobras' floating production, storage and offloading platforms into a steel monster capable of churning out two million green tonnes of log shavings per year.

The one-million-square-metre site will soon have two wood-chipping lines installed by companies willing to take a risk on grinding up a million tonnes each of eucalyptus and pine for export.
