Greaseproof wrapping paper can be sustainable and recyclable, depending on its material composition. Some types are made from biodegradable paper or materials that are recyclable through standard paper recycling processes. However, if the paper is coated with wax, plastic, or synthetic chemicals to make it greaseproof, it may not be recyclable or compostable. Always check for specific recycling symbols or material information to confirm whether it is suitable for recycling or composting.

Greaseproof paper can be considered somewhat eco-friendly for food packaging, depending on its materials and production process. If it is made from sustainably sourced paper and doesn't contain harmful chemicals or coatings (like petroleum-based ones), it is generally biodegradable and recyclable. However, some greaseproof papers are treated with synthetic substances, which could limit their environmental benefits. It's always a good idea to check if the product is labeled as biodegradable, compostable, or made from recycled materials for a more eco-conscious choice.
