By promoting such new products as biodegradable coffee cup lids, the production of plastic waste can be reduced. Actually, the heat resistance of biodegradable materials can be used to make disposable biodegradable coffee cup lids, which has good heat resistance (up to 100°C) and can withstand the temperature of hot coffee. This biodegradable coffee cup lid has high strength and can play a sealing role, which can be composted together with coated paper cups.
It is estimated that 2.5 billion disposable coffee cups were discarded every year in 2011, but now this number may be even higher. However, because the lining of the disposable take-out cup uses a film to ensure that the cup does not leak water, this chemical-containing material cannot be completely degraded and cannot be used for composting, it is almost difficult to recycle. Therefore, almost 99.75% of disposable take-away cups cannot be recycled. A study in 2017 found that only one out of every 400 coffee cups was recycled, even if these cups were thrown into the recycling bin. So we can know the importance of the biodegradable coffee cup to the environment from the biodegradable coffee cup lids.
Without a sustainable environment, you will not be able to have a healthy and orderly economy to provide the resources we need, and you will not be able to use resources more rationally to increase productivity. Now, we should focus on creating biodegradable coffee cup lids as this kind of completely organic and biodegradable coffee cup lid is a good alternative to disposable plastic cup lids in the future.
