Development and utilization of food waste paper recycling

Environmental protection is a worldwide topic and the world is emerging as a “green wave”. In the development of packaging industry, the packaging industry must also consider environmental issues. For this reason, some packaging concepts in developed countries are now offered, and food packaging companies can learn from them.

Reduce environmental pressures and pay attention to material selection. At present, many European and American companies pay attention to the development of "green packaging materials" that meet environmental requirements. When selecting packaging materials, they try to use materials that are easy to handle and actively develop new materials. Pulp forming and packaging are gradually replacing traditional plastic materials that are difficult to degrade. For example, a U.S. company has developed a recyclable paper packaging mat. It uses old newspapers and remanufactures this kind of package, which can replace the now widely used non-degradable foam plastic mats.

Develop edible packaging and focus on functional choices. Food packaging is a big player in the packaging industry, accounting for about 70% of the packaging industry. Food packaging waste also has the greatest environmental pollution. Therefore, it is a big problem for the packaging industry to solve the problem of food packaging waste. Developing edible packaging materials is a good way to solve the contradiction between food packaging waste and environmental protection. The development of edible packaging is a new approach. Its goal is to create a packaging film that does not affect the flavor of the packaged food. This film is edible. For example, a company in Queensland, Australia, made an edible potato chip package that allows people to eat the potato chips and package them without causing waste. Japan has developed edible wrapping paper made of decapto-acetic acid chitosan extracted from shell materials. This fast-food pasta wrapped in edible packaging paper can be placed directly into a hot pot for cooking. The use of edible packaging not only facilitates consumers but also avoids packaging wastes from polluting the environment. It is worth further research and promotion.

Recyclable resources can be used to make good classification and recovery. In view of the fact that packaging waste is the main source of environmental pollution, various countries are trying their best to classify and recycle packaging waste for recycling. For example, the classification and collection of packaging waste in Germany is very good. It not only recycles a large amount of useful materials, but also uses waste to incinerate electricity to generate energy, and it also reduces environmental pollution. Finland and Japan attach great importance to the recycling of paper packaging after recycling. These instructions, on the one hand, do a good job in the development of environmentally friendly packaging products, and on the one hand, the use of renewable resources for waste packaging is an important task that packaging companies cannot ignore.
