Similar to the semi-finished "garbage cube" after Wali compression in "Robot Story", the smiley face bag made of plastic bottles, the physical model of processing construction waste... Piece by piece environmental protection products to the public "tell" the environmental protection story. On October 22, the 2021 Carbon Peaking and Carbon Neutrality Summit of the Middle Reaches of the Yangtze River Urban Agglomeration and the Hunan International Green Development Expo opened in Changsha.
Domestic garbage classification, what about construction waste? "Wall-E" in "Robot Story" helps to recycle construction waste.
At the booth of Hunan Rongcheng Environmental Protection Technology Co., Ltd., through the introduction of engineer Xiao Peng, the public learned little by little where the discarded briquettes displayed in the glass cabinet came from, where they went, and how through a series of fantastic "adventures", after earth-shaking changes, they were once again applied by people.
Respectively, they are derived from the demolition garbage, engineering garbage, decoration garbage in the waste metal and waste fiber fabric paper scraps, from the appearance, it is like the "garbage small square" after being treated by the robot Wali with pressure.
Xiao Peng said that the four types of road asphalt waste, engineering waste, demolition garbage and decoration garbage are the main sources of construction waste. The disposal methods are mainly landfill and comprehensive utilization of resources. "We recycle on site, carry out factory, precise sorting and disposal, and finally recycle and reuse. Our philosophy is to achieve 100% recycling and recycling, so that construction waste will not pollute the environment by landfilling. ”
According to the "14th Five-Year Plan" circular economy development plan, by 2025, the comprehensive utilization rate of construction waste in China will reach 60%.
The recycling of construction waste resources is a key move to build a "waste-free city". Xiao Peng told reporters that not long ago, the company converted a road in Changsha County from a cement concrete pavement to an asphalt pavement, and the raw material of which is recycled road asphalt waste. "The recycling of construction waste helps to achieve carbon peaking and carbon neutrality."
The reporter noted that the exhibits in many booths are very attractive. The staff of multiple booths told reporters that this year's Green Expo hopes that more citizens can truly understand what low-carbon and environmentally friendly products are available and the corresponding production process through vivid image display.
Ms. Zhu, a staff member of the Coca-Cola Pavilion, told reporters that when the children came to the booth, they would soon like our smiley face emojis. Adults will not feel strange when they see it, and through products such as wind and raincoats, 24 packs, and care umbrellas, they will bring the topic of public and environmental protection closer.
13 PET plastic bottles are recycled to generate another weathercoat; 6 PET plastic bottles are recycled to generate an umbrella... Through the "wonderful use" of beverage bottles, it opens up the space for children to think about environmentally friendly products.
"What exactly becomes of plastic bottles after they are recycled" became a topic of curiosity for them. The animation illustrations on the promotional board of the booth detailed the process of PET regeneration for the children: removing the cap label sorting; cleaning agent to remove the attached oil; drying; melting, extrusion, filtration, granulation and other steps to finally form recycled polyester particles.
Compared with the professional text introduction, simple and childlike pictures can directly feedback the production process and environmental protection benefits to the public. Mr. Zhong, who is preparing to take his children to see the exhibition on the weekend, said that it is important to satisfy the curiosity of children, so that they are more interested in understanding the knowledge they have learned through models and pictures.
