Time:2020-09-25

Disposable diaper is one type of disposable consumables in our daily life. According to statistics, every year the United States produces 21 billion disposable diapers which are becoming waste once used. The UK disposes of 2.5 billion of diapers each year. Those disposable diapers mostly will be abandoned and buried in landfills, while diapers cannot easily be decomposed and it may exist for half a millennium in the land. This is not only a waste of big resources but can also create harm to the environment. As such, disposable diaper recycling is quite necessary and important.

Instead of landfills, disposable diapers can be recycled in many ways. For example, in Canada, there is a company using new technology to change the large volume of disposable diapers into diesel. They apply a high-temperature decomposition technique to heat the diapers in a sealed environment with 600-degree centigrade, the diapers will finally turn into fuel after thermal decomposition and carbon chain decomposition. During the whole process, it has no emissions. The produced “Diaper Diesel” is a kind of renewable energy that can be used in many industries. According to this company, every 30 thousand tons of diapers can produce 11 thousand tons of diesel.

Other than diesel, disposable diapers can also be shredded and recycled to other products. During the recycling process, the first step is shredding them into small pieces which can facilitate the separation of the plastic material from the pulp-like material. Then the shredded materials are washed in water which contains the special ingredients. Finally, they will become separated plastic and dehydrated pulp-like materials and they can be used as new material for producing new products.
