Ecoffee Cup - Reusable coffee cups made of polylactic acid - A sustainable alternative Every year, 100 billion disposable cups end up as residual waste in landfills. That's why Ecoffee Cup was created, an environmentally friendly, reusable cup made of polylactic acid. Coffee and tea enjoyment meets sustainable design The reusable cup made of polylactic acid is light and robust, practical for on-the-go and designed with a simple look. The cups have a fully closable, non-drip lid. The sleeve as well as the lid with closable drinking opening are made of food-safe silicone, which is latex-free and specially designed for hot liquids. The entire cup, including cuff and lid, is dishwasher safe. The cups are tasteless and free from BPA, BPS and melamine. The mug is suitable for use in the microwave (Max 800W / 40 seconds). The mugs do not have an insulating layer, so they are not thermal mugs.
