So the car should live on after junkyard – New Technology

From the beginning of the year to be 95 percent of the weight of a car can be recycled. New Technology visited the largest bilåtervinnare struggling to meet the new, tougher EU requirements.

Every year scrapped around 190 000 cars in Sweden. Of those ports around 45,000 in a giant mill outside Halmstad. Several process steps later, they come out in the form of new materials such as iron, aluminum, copper and fuel.

– We and photo booth hire built Scandinavia’s most advanced car recycling, says Kristofer Sundsgård, Production Director at Stena Recycling.

He reports that 91 percent of the car’s weight can be recycled today. It’s not enough. In January introduces new EU requirement that 95 percent by weight must be recycled. Of these, a maximum of 10 percent is burned as fuel. To achieve the target cooperates Stena Recycling few years ago with Bilretur, a national network of 93 dismantlers.

– I’m sure that together we will pass 95 percent by year end, says Kristofer Sundsgård.

At Ny Teknik’s visit is compressed bilkadaver stacked in large piles and waiting to be lifted into the grinder of a giant femfingrad grapple. Before they came here have a dismantlers stripped away tires, batteries, boxes, air bags, liquids and components that can be reused as spare parts. The cleaner the body, the easier to recycle.

The grinder is fast and brutal. The bodies are chopped up by twelve hammer à 300 kg. The rotating at 500 revolutions per minute, a job that requires a 6,000-horsepower engine.

– What remains is pieces the size of a fist , says production Sverker Rosdahl, who shows us around the facility.

shapeless pieces of metal, plastic and other things going on all over the place on a conveyor belt. Here are some of the methods that Stena will use to sort them:

• Facilitate bits, rubber and textiles, drawn up by a fan.

• Large screens sifts heavy pieces in four different sizes. From less than 20 mm to over 120 mm.

• Iron trapped by magnetic coils.

• Bath with various density, certain materials that float, others sink.

• Sensors detect metal pieces and activate the air nozzles that blow them away.

• Different types of plastics are separated by strong air currents.

• metal pieces that technology has finally caught missed manually.

Före New Year the recovery rate is screwed up another few notches. One of the challenges is to improve the sorting of plastics in various grades. To reach the 95 percent target must also picture booth are picking more of this car bodies before they reach Stena’s facility.

In a few years counting Stena Recycling to have a larger and more advanced facility in operation on the neighboring site. There is an abandoned factory of 400 000 square meters today echoes empty. You want the company including building more and bigger densitetsbad to separate different metals more efficiently.

Even plastic sorting should be further refined. The goal is to create cleaner fractions at a lower cost. Now waiting for the company to environmental conditions of the investment is in the 100 million kronor class.

This also applies to finding customers for all recycled materials . The metals are not a problem. The plastic is trickier.

– The market for recycled plastic has been lukewarm, until a few years ago. But manufacturers such as furniture and building materials such as floor shows more interest in recycled plastic, says Anna Henstedt, responsible for environmental issues in industry organization Bil Sweden.

She says that there is much research on the area, including to create different grades of plastic. This allows customers to know what they are buying, while recycling companies know what will be delivered. Price is also an important aspect. Recycled plastics must be cheaper than virgin raw materials.
