World Centric' s mission is to provide sustainable products for a better world. The watchwords of sustainability - reduce, reuse, recycle - direct us towards our ultimate goal of a zero waste economy. In the meantime, in an economy that does produce waste, World Centric' s disposable food-service products are designed to transform waste into healthy, new soil through composting. World Centric® 12 oz Kraft paper cups are made from FSC® certified paper with a bio-lining made from plants. These disposable hot cups are great for coffee, tea and hot cocoa, and are safe for liquids up to 220°F. Our coffee cups are compostable, eco-friendly, and freezer safe. These cups will compost in 2 to 4 months in a commercial composting facility. Not microwavable.
