Disposable tableware can be divided into the following three categories according to the source of raw materials, production process, degradation method, and recycling level:
1. Biodegradable products: paper products (including pulp molding type, cardboard coating type), edible powder molding type, plant fiber molding type, etc.;
2. Light/biodegradable materials: light/biodegradable plastic (non-foaming) type, such as photobiodegradable PP;
3. Materials that are easy to recycle: polypropylene (PP), high impact polystyrene (HIPS), biaxially oriented polystyrene (BOPS), natural inorganic mineral filled polypropylene composite products, etc.
No, environmentally friendly dinnerware includes three types: easy to recycle, easy to dispose of, and easy to degrade. Degradable is just one of them. Degradation is only a supplement to recycling, that is, degradable packaging can be considered when a certain packaging material is difficult to recycle or has low recycling value after use.
No, no materials should be thrown away randomly, and sorting and recycling should be conducted actively to reduce waste of resources and environmental pollution. Even degradable products require reasonable disposal or utilization. It is nonsense to talk about product degradation speed and degradation products without specific environmental factors.
