Finnish company’s garbage reducing invention

A
new briquetting technology by the Finnish company Evac could see a reduction in
ships’ garbage volume by a factor of ten.

The
machine, paired with Evac’s mixed-waste macerator, can create dry briquettes of
waste that can be stored when a ship may not use its incinerator, the garbage
room will be filled floor to ceiling in two days,” says Jari Jokela, PhD, Evac
Senior Process Specialist.
“Evac’s
briquetting technology enables a cruise ship to potentially operate without
incineration or landing the waste for a full two-week voyage.”
“Waste stored in the traditional
plastic bags has density of 50 to 60 kilos per cubic meter, but the briquette’s
density is 550 to 600 kilos per cubic meter,” adds Jokela.
It is estimated that the space
savings translate to for landing or incinerated at sea.
“In an environment a dramatic 25
per cent reduction in operating costs when compared to incineration where
diesel and energy consumption is considered.
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.
