CIRCA is high quality porcelain made from post-consumer ceramic waste. About 11 million kg goes to landfill annual from Dutch 2nd hand stores only. With them we create valuable jobs for people with poor job prospects. We turn waste shards into new clay recipes, and make it a valuable resource for its own production cycle and result in reduction of mined resources and CO2 emissions transport/drying/firing. We make CIRCA clay with various % of shards in a recipe, up to 100%. We can change the recipe to fit the production technique, make the waste more/less visible and even self-glazing.
