[Case of Plastic Material Identification Device] Prevention of PVC Contamination in RPF Solid Fuel
Plasil PI-100
A simple plastic material identification device found after 10 years. It is useful for producing high-quality RPF.
Plastic Material Identification Device Case Study 9 ■Industry: Recycling Industry ■Application: Prevention of PVC (polyvinyl chloride) contamination in RPF solid fuel, etc. 【Customer's Challenges】 The company, engaged in recycling-type dismantling and waste recycling business in Yamagata Prefecture, compresses and processes "waste plastics" and "paper scraps" emitted from various business locations to produce RPF solid fuel. To manufacture high-quality RPF, it is crucial not to mix raw materials containing halogens, such as PVC. However, it is difficult to determine the plastic material by appearance alone, and in the past, sorting was done using a flame color reaction with copper pipes, which posed a problem due to the labor-intensive nature for on-site workers. Additionally, there are concerns about health risks from inhaling combustion gases. *For more details, please refer to the PDF document or feel free to contact us.*

basic information
[After Introduction] ■ Thin materials such as films can be easily identified by folding them, making them user-friendly. ■ It is unfortunate that black cannot be distinguished due to the nature of near-infrared spectroscopy, but it has been helpful to use it for about a year and a half without any particular troubles. ■ In addition to utilizing "Plastics" during the acceptance of expected RPF raw materials, we are also promoting the use of "Plastics" at mixed waste sorting facilities to increase the raw materials that can be directed towards RPF production. *For more details, please refer to the PDF document or feel free to contact us.

■Introduction Yamamoto Manufacturing Co., Ltd. is a machinery manufacturer founded in 1918 in Tendo City, Yamagata Prefecture. We have achieved the top market share in Japan for agricultural machinery, particularly grain dryers and straw cutters. "Because we are a company that has walked alongside agriculture, we want to contribute to improving the global environment that supports food production." This aspiration, combined with our cultivated technology, led to the creation of the polystyrene reduction machine "High Melter." Through the provision of our products, we aim to create a bright future for the industry together with those who are challenging themselves in the recycling industry (*). That is our mission. ■Thoughts on Development The concept of the "circular economy," which views discarded items as resources and aims to circulate resources without generating waste, is gaining attention. However, the recycling industry (*), which plays a significant role in this, does not receive much public interest, and many companies are struggling with labor shortages. Through manufacturing, we want to shine a spotlight on this industry and bring about change. This is the sentiment embedded in all the environmental equipment produced by Yamamoto Manufacturing Co., Ltd. (*) In contrast to the "arterial industries" that produce goods, the industries that collect, recycle, reuse, process, and dispose of waste are referred to as "venous industries," likening them to the circulation of human blood.
