In a pilot project in recent years, the Kafferosteriet in Karlstad has worked to produce a nutritious soil where coffee residues are mixed with wood fibers into a peat -free soil. So far, more than 100 tonnes of coffee have been manufactured, and now they have reached so far that coffee words have come out in the trade.
– What we have done now is that we have got a continuous flow, so now everything our coffee spill goes out to landfill to become a coffee word, says Annika Djurberg, project manager for the production of coffee words.
The coffee residues provide mull and nutrition to the soil, while using the spillage that was previously burned up.
Coffee sump – an old housewife trick
– Using coffee sump in the soil is an old housewife trick, to provide extra nutrition to cultivation soil. Now we take it a step further, says Anders Thorén, communications manager at Löfbergs.
Instead, coffee beans are used at the coffee roast, both roasted and concerned that for some reason cannot be used for the intended production to the earth. It was about incorrect roasting, damaged packaging. Then there will also be a lot of silver membranes in the production, that is, the outermost shell of the coffee beans, which now also ends up in a special compost pile to become a coffee word.
– We have managed to get our waste down to 0.32 percent, and with the coffee words we also tie the cycle together, says Annika Djurberg.
