To allow the resumption of educational activities in full compliance with the guidelines provided by the anti-Covid legislation, most Italian kindergartens have been engaged in an intense work to review the normally adopted practices.
The comparison between metal and plastic has always been a much debated topic. In fact, until some time ago, plastic products were considered to be of lower quality than their metal analogues. Nowadays, however, advances in the production and industrial processing of plastic materials can increasingly better satisfy the demands of many sectors.
When we talk about plastic, we generally refer to a series of organic substances made of polymers, that is, molecular groups organized in repetitive units, pure or mixed with additives. The most common polymers are derived from petroleum, but there are also plastics developed from other sources.
Plastic is considered a newly invented material, but its origin goes back to the early civilizations. In fact, some natural polymers such as amber, horn and rubber, the structure of which inspired the invention and production of modern plastics, were already used by man in ancient times.
With EU Directive 2019/904, the member countries of the European Union, by 3 July 2021, will have to ban many disposable plastic products for which there are alternatives, impose the economic participation of producers to the costs of disposal of some plastic waste, and undertake initiatives to promote the recovery, recycling and reuse of materials.
