“The Netherlands is a hot spot for the global circular economy. Our country's waste recycling rate is 79%, and the recycling rate of construction waste is 96%.”

At the recent “High-Level Forum on Industrial Solid Waste Comprehensive Utilization (International) in Beijing, Tianjin and Hebei and the Surrounding Areas”, Fryke Wane, Associate Partner of the Netherlands Institute of Corporate Social Responsibility and Senior Expert in Solid Waste Management and Circular Economy When Jack listed this set of data, many participants at the scene issued amazement: "Wow, it's so high!"

Amazing may also be due to a huge gap. As far as construction waste is concerned, according to statistics, the total amount of construction waste generated in China in the past few years is between 1.55 billion and 2.4 billion tons, but the recycling rate is only about 5%.

Efficient waste resource management system

“The Netherlands is a country with a very high population density. We must deal with resources in a creative way.” According to Frick, the Netherlands currently has a population of 17 million and a land area of ​​only 41,800 square kilometers. The limited space and resources determine the way the Dutch must take the circular economy.

In 2015, the Netherlands ranked 4th in the Global Innovation Index. It turns out that the Dutch innovation genes also seem to be applied to the recycling of resources.

The Netherlands produces 60 million tons of waste each year, 79% of which is recycled. “The vast majority of the rest generate energy through incineration, and only 3% are landfilled.” Wei Anna, Infrastructure and Environmental Counselor of the Dutch Embassy in China, said that in the past six years, the recycling rate of plastic packaging has increased in the Netherlands. Doubled. In 2014, the recycling rate of waste paper and waste paperboard in the Netherlands reached 82%, while the recycling rate of metal was as high as 94%.

This achievement was first based on the unique waste resource management system in the Netherlands.

The Netherlands has been implementing a waste sorting system since 1979. It clearly defines producer responsibility and levies a landfill tax. In order to promote the circular economy, the Netherlands fully plans the recycling of resources, effectively cooperates among government departments, and drives the waste management industry to participate actively. It is worth mentioning that the Netherlands has formed a unified data statistics system and monitoring system for waste recycling.

Building waste recycling is a model

The recycling of construction waste is a major highlight of the Dutch recycling economy. According to Frick, the Netherlands produces 25 million tons of construction waste per year, and the overall recycling rate is 96%. If it is only for inert construction waste such as cement, bricks and gravel, the figure is 99.8%.

“We attach great importance to the recycling of construction waste because it is the most important source of all waste in Europe, accounting for almost 30%.” Fryk said that in order to improve the recycling rate of construction waste, the Netherlands has also formed A unique system of legal constraints.

For example, the Dutch Environmental Protection Regulations stipulate that construction waste must be classified and then disposed of. Hazardous waste needs to be registered and landfill is prohibited.

This determines the process of treating construction waste and also strives for excellence. According to Frick, the construction waste should be cleaned before the backfilling, that is, the dangerous construction waste is separated, and then the wood, metal, glass, plastic, etc. are separated for recycling, and then the remaining cement and bricks are removed. Inert construction waste such as blocks and gravel is screened and crushed, and finally used for roads, dams, and coastal projects.

“In the process, the construction waste recycling technology in the Netherlands has developed rapidly.” Frick said that in the past, construction waste disposal in the Netherlands relied on crushers, separators and turbines; now the automatic waste recycling system can rely on magnetic force. Screening machines, X-ray separators, color separators, etc., automatically screen out plastic, non-metal, concrete and brick particles.

Can't just loop for loops

In September last year, the Dutch government launched a national circular economy project. The project proposes that by 2050 the Netherlands will achieve a comprehensive circular economy and achieve double-track growth in economic development and resource recycling.

“In order to achieve this, the Netherlands has begun to take action at all levels of society and set clear goals.” Wei Anna introduced, including 20% ​​reduction in the consumption of raw materials such as minerals, fossil energy and metals by 2030. At the same time, the Netherlands is also investigating the problems faced by the circular economy and forming a reasonable solution. Wei Anna believes that it is not only ecological factors but also economic factors that drive the project. She explained that the Dutch research institutes initially estimated that the Dutch circular economy increased the transaction volume of 7.3 billion euros and 54,000 jobs for each of the various fields involved. In addition, the development of circular economy can reduce the annual import of raw materials in the Netherlands by about 100 million tons, equivalent to 1/4 of the total annual import of raw materials in the Netherlands.

Frick also stressed the importance of market factors to the circular economy.

He believes that in the case of construction waste, a strong legal and regulatory framework will help the market to form, but whether the circular economy can grow and rely on a variety of market factors. For example, environmental testing of recycled materials and labeling of quality can increase the customer's willingness to use. As far as possible, the balance between the price and quality of recycled materials can also increase their market demand.

"The development of a circular economy requires the government's determination, but it is legally bound, and without market regulation, the circular economy will not develop effectively." Fryk said.
