Throughout its century and a half of existence, plastic has been gaining more and more weight in the activities of companies and people. Today this material is a challenge from the sustainability point of view, given the need to implement recycling systems that minimize its impact on the environment.

Despite the efforts that are being carried out in regions such as the European Union (EU), official data reveal that, in countries like Spain, barely a third of the urban solid waste generated is recycled, which requires to continue working intensively on two major challenges: a more responsible consumption in the use of plastic, and the commitment of innovative systems for the reuse of this type of waste.

What is Spain doing in terms of recycling?

There are different companies that are working on projects to optimize waste in each of its recycling phases and that can generate new assets that are useful from plastic. RepetCo, for example, manages, through its own patented and environmentally friendly system, to recycle all kinds of multilayer PET/PE food packaging of post-consumer origin. This process allows to generate rPET pellets and rPE that can be used again in the food industry as trays and containers of multilayer PET / PE sheets. The company thus offers a solution to the recycling of food packaging in a sustainable way from an economic and environmental point of view, something that had not happened until now since these packagings were burned or buried in landfills.

South Korea encourages food recycling

Outside of Spain, there are other examples of waste management at an international level. In Asia, South Korea and Japan stand out. Focusing on the first, the Government has focused on food that is wasted and that, if not treated correctly, ends up causing air pollution in the form of greenhouse gas emissions.

Hence, the country’s authorities have developed in response to food waste a strategy that consists of marketing biodegradable bags for organic waste that, when deposited in the corresponding containers, oblige the user to identify and pay a specific price for each kilo. Under the premise that whoever deposits more waste pays more. In a short period of time, it has been possible to reduce economic waste per person per year from 130 kilos to around 10. In addition, an aid plan has been promoted for companies that can reuse these wastes, manufacturing, for example, food for the livestock sector, fertilizers or even biogas for combustion, from which various industries are benefiting.

Japan focuses on waste separation

In the case of Japan, families are responsible for separating and organizing the different waste they generate, which serves so that later the urban waste management system can collect each one of them (around thirty) according to a previously established schedule.

Under the premise of achieving the goal of zero polluting emissions in the country, the Government is investing in environmental education for all layers of society, ensuring that the commitment to sustainability appears in the home and is transmitted to all social aspects. In fact, the next withdrawal of all recycling containers from the main Japanese cities has already been announced since it is expected that they will not be used in the future.

Sweden, the European example in waste treatment

Among the commitments of the Swedish Executive for some years, is to lower the price of the electricity bill thanks to the incineration of resources to produce energy. For this reason, the increasing commitment that is being achieved among citizens to correctly separate and reuse waste is essential, facilitating the subsequent task of allocating each type of waste to burning systems for energy production.

The growth in the recycling rate per person per year has been such in the last decade that it is estimated that the figure of 250,000 households that receive a substantial part of their electricity supply through the burning of waste will soon be reached. From the point of view of harmful emissions, the Scandinavian country is one of the leaders of the Old Continent in terms of reducing CO2 levels and some of its neighbors, such as Denmark or Finland are initiating similar recycling programs given the success in developing your model.
