Food waste depacking with Paddle Depacker<br />

Bio Energie Centrum – sustainable, responsible, innovative!<br />

Since our foundation in 1999, we have made it our business <strong>to</strong> generate<br />

valuable energy from biowaste and thus enable municipalities,<br />

companies and private households <strong>to</strong> dispose of their waste<br />

sustainably. In this way, everyone can actively contribute <strong>to</strong> climate<br />

protection.<br />

Our company produces sustainable energy from waste in a careful<br />

and environmentally friendly manner and feeds it in<strong>to</strong> the electricity<br />

and district heating grid. This energy is generated in our biogas<br />

plant by fermenting green waste, food and organic waste. The material<br />

is hygienised by heating and methane gas is produced in a<br />

downstream fermentation process, which is converted in<strong>to</strong> electricity<br />

in block-type thermal power stations. We supply the generated<br />

energy <strong>to</strong> municipalities and companies in the form of electricity<br />

and heat.<br />

Due <strong>to</strong> new German legislation, BENC was looking for a new way of<br />

depacking. Together with Mavitec Green Energy, the solution was<br />

found in the Paddle Depacker, designed <strong>to</strong> separate the organic<br />

material from the packaging. The Paddle Depacker turns foodwaste<br />

in<strong>to</strong> organic soups and delivers a very clean organic output that is<br />

extremely suitable for biogas installations, with official lab results<br />

of less than 0.5 % plastic & metal packaging in the organic output.<br />
