Upcycling is the opposite of downcycling,




Upcycling is the opposite of downcycling, which is the other face of the recycling process. Downcycling involves converting materials and products into new materials of lesser quality. Most recycling involves converting or extracting useful materials from a product and creating a different product or material.[1]
The terms upcycling and downcycling were first used in print in an article in SalvoNEWS by Thornton Kay quoting Reiner Pilz and published in 1994.[2]
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 block was scrapped. In the road outside his premises was the result of the Germans' demolition "waste" recycling. 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?
