The company’s main focus lies in the recycling of various kinds of post-industrial and post-consumer plastics, as well as producing recycled plastic pallets, pulpwoodplastic composite (WPC), and refuse derived fuel (RDF). In addition to the latter, recycled bags, notebooks, umbrellas, flower pots, garbage bins and textiles belong to their recycled products portfolio.
Turning waste into value
Through its self-operated collection system spreading across the entire city, Luhai sends all waste from “recyclable bins” to its recycling center, where waste is being sorted, reprocessed and given a second life. Once the collected materials enters the sorting process, TOMRA’s sensor-based sorting solutions sort the respective materials mainly consisting of PET, Tetra Pak cartons, PE and PP into high purity fractions, ready to be reprocessed into pellets and new products. It is by means of TOMRA’s powerful NIR sensors that the smallest differences between various materials can be determined and high purity yield achieved.
In addition to collecting recyclables from self-operated outlets, Luhai’s recycling plant also takes in waste collected by the collection system run by local municipal government and surrounding cities.
Integrated waste management operation
Luhai’s waste management system is active in three areas: waste collection network, logistics operation, and recycling center.
Every day, the Luhai logistics team collects recyclable waste from blue bins and sends it to a nearby collection point/station where the collected waste undergoes an initial manual sorting and baling process before being sent to the sorting centre.
In the sorting center, the materials then go through an extensive sorting process combining both automatic sorting and manual control and are separated by color and material type to obtain high-purity PET, PP, PE, Tetra Pak and cardboards. At this step, TOMRA’s sensor-based sorters play a key role and ensure high purity and high recovery rates of the recycled materials while significantly reducing the number of manual pickers.
In a subsequent step, the seperately sorted PET, PP and PE items are then extruded, granulated and thus turned into high-quality recycled pallets.
Unlike PET, PP and PE materials, Tetra Pak cartons undergo a paper-plastic-separation process to produce pure paper and plastic fractions. While the paper generated from cartons is used to create recycled pulp, PE film is mixed with other PE materials and goes through the same extrusion and granulation process as the previously sorted PET, PP and PE items.
China’s national pilot recycling site
The recycling center of Luhai is a national pilot resource recycling base covering an area of more than 86,000m2. The base is designed to process 150,000 tons of solid waste annually. Equipped with leading recycling and sorting technology, such as TOMRA’s, the site is frequently visited by Chinese government delegations from other cities, by recycling players, and most recently also by representatives from companies across the plastic value chain.
