There are many kinds of cartons in the supermarkets for juices, milk, soups and others. Everyone of it is made with nearly 80% of pulp. Inside and outside they are covered with polyethylene. And products which should be durable are covered by a filmy aluminium skin in addition to the polyethylene. With special procedures is a chance to recover the pulp to produce new products. In 1991 starts the packaging ordinance and the usage of sales packages go down. To reduce the licence fees the producers have a look on their usage of packaging material. And they try to minimize unnecessary packing materials or reduce the weight, use refill packages and concentrates or change the packaging materials with eco-friendly packages. So the packaging ordinance affected the product stewardship. The sorting in yellow tonne, white-, green- and brown glasses and paper reduce the domestic refuse. And this effect the operating costs because waste management enterprises collect them without extra costs. The fees are already in the prices.
Plastics can be recycled by their raw materials or by their substance. If they are recycled by their substance, they are fused in and used to produce new products. Normally this happen by producing an intermediate product called recycled plastic materials. The quality of the product depends on the pre collection. A new method to use old plastic in the reduction of hot metal is found. The furnace is filled with ore and coke. From downside are blown in hot air and the plastic agglomerate as reducer. So their come gases like carbon monoxide and hydrogen and this drop oxygen from ore. And so is no need of heavy oil in the entire process. But there are methods to win oil from the plastics too. To do so the agglomerate is given directly in the facility and is made fluid with high temperatures near 400°C and high compression. So we get a mixture of fuel and heating oil, this can be used to producer other refinery products.
