Sorema supplies large-scale plants for material washing

As a subsidiary company of the Previero Group, Sorema supplies the industry with large-scale equipment for material washing. At the same time, the company also cooperates with companies that directly process blanks. PET recycling technology has been consolidated in Europe and the United States, and market growth is directly dependent on the growth of bottle recycling (unless bottles are exported directly to the Far East). Emerging countries are the most profitable markets. Because of the rapid growth in consumption in these markets, environmental awareness has gradually become a common requirement and a priority for social development. In Eastern Europe, the former Soviet Union, the Republic of the Congo, the Middle East, and North Africa, bottle recycling is often lower than in Europe. In view of this, Sorema has developed small and medium-sized integrated equipment to facilitate the reduction of users' technical and investment risks in recycling projects. The design of various types of recycling equipment is divided into five phases. The first stage involved the feeding of materials. Therefore, specific analytical methods were designed for the existing bottles on the market and based on the specific requirements for the determination of key contaminants in order to develop locally-accepted bottles; the second stage was for the blank market. Inspect, according to the use of the region or potential users, establish a user quality control system, in order to ensure the quality of the billet material.

Then, equipment selection. To this end, Sorema has developed modular technologies to ensure the highest degree of flexibility. Each set of equipment can be integrated with the new module in the future to increase the degree of automation when labor, production costs increase and the recycling market expands. The company can provide 8 sets of basic modules: feeding, ensuring that the bottles flow evenly into the equipment; sorting, for sorting out non-PET bottles or objects; grinding of the bottles; high temperature and strong washing for separating and sticking Adhesives, paper scraps and surface contaminants; low-temperature washings for polyolefin sorting; mechanical drying and high-temperature drying; aerodynamic sorting for the elimination of particulates and light weight films found in PS, PA, PET, PVC Mix and pack.

In the fourth phase, all facilities needed for the equipment will be taken into consideration. This phase also includes staff training and technical summary preparation as required by the equipment manager. Finally, wastewater should be properly managed, of which production water is the most critical factor. The washing plant can be regarded as a "black box" where dirty bottles and clean water are input, after which clean sheets and dirty water are output. Proper water management ensures process quality and product quality.
