Titanium, stainless steel or glass boards feature zero micro plastics – they’re also hygienic and dishwasher safe. Boards made from these materials can be recycled after use if they don’t include plastic non-slip feet. The issue with these materials is the large fossil fuel usage required in their production, and the destructive effect they have on knife edges. Cutting on these surfaces creates more noise which can be irritating, but they are long lasting.
