Making briquettes from aluminium shavings gives a greater yield – depending on the alloy and operating conditions saving – saving 50 to 200 € per ton. (prices from 2007). Unlike loose shavings, briquettes have a predictable and low residual moisture content, which is an advantage when marketing them.

Cooling and lubricant fluids are pressed out during the briquette-making process and pumped back directly into the filtration system.

The shape of the briquettes gives a smaller surface area than with loose shavings – during smelting there is a burn-off of only 3-5%. Energy costs are also reduced.

Processing at the point of origin and greatly reducing volume results in the production of a very light, easy-to-handle secondary material.
