“Waste stored in the traditional

Jokela says inspiration for the technology came
from witnessing how sawmills were creating briquettes.

Evac created a similar technology, in a much more
compact form, for use orkers and a reduced volume of garbage would mean fewer
trips to remove waste from the platform. at sea.

The technology could also be used on offshore oil platforms as they are
typically staffed by up to 1,000 w.
