[Industrial Waste_Problem Solving Case] Solutions for crushing of fluff, crushing of home appliance plastics, and pre-treatment before incineration.

Active in large-scale fluff processing.

**Case Study on Problem Solving** ■ Effects of Implementation We have successfully crushed waste plastics to under φ20mm, allowing for stable shipments for cement fuel and paper mill fuel. It has demonstrated significant effects with performance as expected. The machine is quieter than anticipated. ■ Deciding Factors for Purchase With the proposal to utilize subsidies, we were able to proceed with the purchase of a larger model by keeping the budget lower than usual. By embedding the frame in the pit and arranging a steep conveyor, we were able to make effective use of space. ■ Model Introduced - UC-250 (250kw) - Screen Size: φ20mm - Application: Refuse-derived fuel (cement, paper mills) *For more details, please refer to the PDF document or feel free to contact us.*

• Crusher

Contributing to the stable operation of the incinerator.

**Case Study on Problem Solving** ■Effects of Implementation By adjusting the particle size of the input material, we have been able to operate the incinerator stably. We are satisfied with the stable supply to the downstream equipment of the crusher. ■Deciding Factors for Purchase - The frame design considers ease of maintenance and wear resistance. - The flexibility in meeting the special requirement for outdoor specifications. - We were attracted by the ability to respond flexibly to other needs. ■Model Introduced - UC-132 (132kw) - Screen size: φ50mm - Application: Crushing for volume reduction and particle size adjustment before incineration of industrial waste. *For more details, please refer to the PDF document or feel free to contact us.*

• Crusher

We would like to introduce a case where the UC series single-shaft crusher was introduced as a dedicated aluminum crushing machine.

【Case Study of Problem Solving】 ■Effects of Implementation When crushing aluminum of various shapes, the shredder produces shreds of the expected size, allowing for the discharge of materials suitable for downstream processes. ■Deciding Factors for Purchase The noise level during shredding was lower compared to other companies, and the processing capacity exceeded expectations. The ability to address both pre- and post-crusher equipment as a package was a key factor in the purchase decision. ■Model Introduced ・UC-200 (200kw) ・Screen Size: φ60 ・Features: Dedicated aluminum crushing machine *For more details, please refer to the PDF document or feel free to contact us.

• Crusher

Recycling/energy recovery of 30 tons/month of waste generated within the company with added value.

**Case Study on Problem Solving** ■Effects of Implementation By crushing approximately 30 tons/month of waste generated in-house, such as poly drums, we were able to add value and recycle or convert it into fuel. ■Factors in Purchase Decision - It can effortlessly crush difficult-to-process materials like FIBC bags. The precision is excellent, and the cutting performance is outstanding. - Compared to other companies, the lower running costs were a decisive factor in the purchase. ■Model Introduced - UC-75 (75kw) - Screen size: φ30mm - Various conveyor systems for downstream equipment *For more details, please refer to the PDF document or feel free to contact us.*

• Crusher

Active in the stable crushing of mixed plastic home appliances.

**Case Study on Problem Solving** ■ Effects of Implementation When crushing mixed plastic from home appliances, it can be coarsely crushed to the expected size, allowing for stable flow to downstream processes. ■ Deciding Factors for Purchase - Due to its low-speed rotation, the noise during crushing is very low, and the processing capacity met the expected test evaluations. - Compared to other companies, the initial and running costs were lower, which was a decisive factor for the purchase. ■ Model Introduced - UC-45 (45kw) - Screen Size: φ40mm - Application: Primary crushing of mixed plastic from home appliances *For more details, please refer to the PDF materials or feel free to contact us.*

● The production time for casting prototypes can be shortened! Since model production is not required, the time needed to create prototypes, which previously took about a month, can be significantly reduced. ● Model costs can be reduced! By directly producing sand molds from 3D data, there is no need for model production costs. If changes to the model are necessary, they can be addressed by modifying the 3D data. ● Similar products with different shapes and dimensions can be prototyped simultaneously! With one molding process, different products with similar shapes or varying dimensions can be molded at the same time. This allows for the verification of multiple types in a short period.

The "Mechanical Stitching Method" by Nichinichisui Road Machinery Co., Ltd. is a new technique that allows for the repair of metal cracks without the application of heat. By using special bolts and reinforcement plates, cracks are physically removed, and repairs are made without causing any thermal impact to the base material. Repairs can be carried out even in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. ◎ For more details, please contact us. ◎ If a detailed technical explanation is needed, please contact us.

● This is a leak testing device for small electronic components that does not use fluorinated inert liquids (PFAS-free). ● There is no longer a need for unstable visual confirmation through liquid immersion testing. It adopts a quantitative testing method that allows for stable pressure leak testing. ● It is a tabletop leak testing device specifically for gross leaks, with accuracy equal to or greater than that of liquid immersion testing. ● The detectable range is approximately 1×10⁻² Pa·m³/s to 1×10⁻⁶ Pa·m³/s (varies depending on the target product). ● It is suitable for sealed structures ranging from a few millimeters to a maximum of 80 × 70 mm.

We developed a system that expands the functions of the electronic manifest ASP "KENET" to record the traceability from waste to the creation of recycled resources using blockchain technology. In May 2025, as a pre-service, we implemented registration functions from waste registration to the input of the recycling process and the completion of recycled resources. In January 2026, we newly developed functions for inventory management and shipping of recycled materials. The system also includes a CFP registration function for recycled resources, allowing for data input on the decarbonization effects of resource circulation. We aim to utilize the waste management functions cultivated over 18 years with KENET to advance into the field of resource circulation and work towards the effective use of waste for a circular society.
