Secondly, when we talk of disposable products in medical environments, we cannot forget that all products coming into contact with organic liquids are required to be treated as special waste.
For further detail regarding this topic, click here for an article dedicated to Disposable products in medical environments.
Paper cups
Using paper as a raw material for disposable cups may seem like a great idea. Indeed, paper cups are often presented and advertised as compostable, recyclable, or even “organic”. However, this is not borne out completely by real facts, because paper cups are never totally devoid of plastics. In fact, paper cups have an internal coating of plastic to prevent their liquid content coming into contact with the paper. This layer represents approximately 5% of their total weight, meaning a greater consumption of energy and CO2 emissions during the production phase. Furthermore, the process of separating paper and plastic is complex and especially costly and for this reason paper plastic cups, or plastic plates are often rejected by recycling plants and are directed to landfills.
Another element to consider is the European-wide regulatory standards that significantly restrict the use of recycled paper fibre in products designed to come into contact with food products (packaging, but also plates and glasses). Without taking into account that paper cups are twice as heavy as common plastic cups and therefore impact on the environment when transported.
Bio-plastic cups
We define bio-plastic cups as cups made from processing corn, bamboo or sugar cane. In theory, this solution seems the best because it offers an eco-compatible solution, similar to the traditional solution. The production and use of bio-plastics are more advantageous compared to conventional plastics, both from the point of view of energy requirements as well as from the point of view of greenhouse gas emissions. Nevertheless, this solution greatly impacts on the environment due to the use of fertilisers and chemical substances in the cultivation of the necessary renewable raw materials, as well as the use of land and water. Add to this the environmental impact in transporting the biomasses required in its production.
