We talked about the impending EU Demolition Waste Streams directive. "Recycling, he said, "I call it downcycling. They smash bricks, they smash everything. What we need is upcycling where old products are given more value not less." He despairs of the German situation and recalls the supply of a large quantity of reclaimed woodblock from an English supplier for a contract in Nuremberg while just down the road a load of similar blocks was scrapped. It was a pinky looking aggregate with pieces of handmade brick, old tiles and discernible parts of useful old items mixed with crushed concrete. Is this the future for Europe?

As we have noted, most recycling is actually ''downcycling''; it reduces the quality of a material over time. When plastics other than those found in soda and water bottles are recycled, they are mixed with different plastics to produce a hybrid of lower quality, which is then molded into something amorphous and cheap, such as a park bench or a speed bump... Aluminum is another valuable but constantly downcycled material. The typical soda can consists of two kinds of aluminum: the walls are composed of aluminum, manganese alloy with some magnesium, plus coatings and paint, while the harder top is aluminum magnesium alloy. In conventional recycling these materials are melted together, resulting in a weaker—and less useful—product.
