RFID identification technology helps Finland achieve national garbage recycling

Around the "One Axis and Four Pavilions" of the Shanghai World Expo, the "Pneumatic Waste Transfer System", known as the "Green Bud," has become familiar to tourists. This smart, low-carbon "underground vacuum cleaner" came from Finland. In Finland, similar waste disposal systems have penetrated into every corner of the city, and even garbage recycling in the subway operating system depends on this.

Pneumatic waste transportation device concentrates the garbage to the underground garbage station, and then transports the waste through the container to the recycling center for processing and processing, effectively improving the level of residential waste management in Finland, even in public places such as squares, railways, bus stations, and parks. It has also been effectively used. Compared with previous waste management systems, this type of underground pipe-type waste treatment reduces the number of garbage trucks and trash cans, reduces waste gas emissions and noise pollution of garbage trucks, and makes garbage disposal safer and more reliable, reducing fire hazards. happened.

In Finland, garbage recycling is not only a deeply rooted awareness of environmental protection, but it is also developing into a specialized and sophisticated industry. Plastic bags are not visible in hotels in Finland. Instead, recyclable paper bags are used instead. The trash can also clearly show ordinary waste, biological waste, and metal waste. After the hotel collects and puts the corresponding color labels on the bags, it can be left unattended in the ordinary trash can. The rest of the work will be handled by a garbage recycling company called Metrosense. After the garbage bag is sent to the recycling center, the RFID electronic tag in the sticky note will be automatically detected. The robot will empty the garbage bag and send the garbage to the corresponding garbage storage box or compressor. The garbage bag itself is centralized to the special storage. In the box, unnecessary landfills are reduced, and the mixed garbage is ground and compacted in place.

In Finnish parks and roads behind houses, there are often several “big belly” dumpsters buried deep underground. This is an economic and ecological waste recovery system that Finns have tried. This vertical, deep-buried solid waste collector has four to five times more capacity than a conventional ground trash bin, and the number of emptyings and the use of garbage trucks are greatly reduced, thereby saving fuel energy and carbon emissions. Deep buried solid waste collectors collect and classify waste paper, glass, biodegradable waste, mixed waste, etc., thereby widely spreading the concept of waste classification and recycling to the public. "Urban garbage disposal should start from the classification of garbage at the source," said one Chinese based in Helsinki for more than two decades.
