Plastic is used everywhere around us. While plastic enriches our lives and makes them more comfortable, as a company involved in plastic, we believe that, rather than just enjoying the convenience and comfort of plastic, we must also face the responsibility of handling it properly. ### Plastic is incredibly useful These days, plastic is everywhere around us As technology continues to advance, it has become possible to manufacture products which are strong but have very complex shapes at the same time, and this has opened the door to the use of plastic in a growing number of fields. From household appliances and daily commodities to industrial equipment like smartphones, personal computers and automobile parts. Not a day goes by when we do not hold plastic in our hands, and it has become an indispensable part of our lives. ![AdobeStock_408266576@2x](https://eng.harmo-net.co.jp/hubfs/sustainability/AdobeStock_408266576@2x.jpg "AdobeStock_408266576@2x") ![AdobeStock_320996786@2x](https://eng.harmo-net.co.jp/hubfs/sustainability/AdobeStock_320996786@2x.jpg "AdobeStock_320996786@2x") ### Plastic products and environmental considerations In 2015, the United Nations Summit announced the SDGs (Sustainable Development Goals). Against such a backdrop, plastic has been at the heart of a growing discussion, mostly centered on the problems of garbage and microplastics, with its impact on marine environments. With the emergence of new materials like environmentally friendly biomass plastics, we believe that HARMO too, as a company involved in the production of plastic products, must contribute to the creation of a circular society and work on what it can do towards that goal. ![循環型社会とプラスチックの共存のために](https://eng.harmo-net.co.jp/hs-fs/hubfs/pic_sustainability_03.jpg?width=2732&height=936&name=pic_sustainability_03.jpg) SUSTAINABILITY Towards the coexistence between plastic and a circular society How HARMO products can contribute to the environment ### 01. More effective utilization of raw materials #### Promoting the reuse of resins used as raw materials for plastic and reducing waste in production processes ![樹脂材料の再利用促進](https://eng.harmo-net.co.jp/hubfs/pic_sustainability_04.jpg "樹脂材料の再利用促進") Improving the recycling rate of raw materials with the help of gran cutters Our gran cutters, which incorporate an original cutting mechanism, can cut sprues and runners into fine granules, thus facilitating the reuse of resins used as raw materials for plastic. This has improved the recycling rate of raw materials that up to now had been difficult to reuse with only conventional crushers. ![生産工程での材料のムダ削減](https://eng.harmo-net.co.jp/hubfs/pic_sustainability_05.jpg "生産工程での材料のムダ削減") Reducing waste of raw materials by automating production processes Our Total Link management system makes it possible to collectively configure, activate and monitor injection molding peripheral devices. Proper management of the production cycle based on precise calculations helps eliminate waste in the supply of raw materials. ### 02. Approach to carbon neutrality #### Products that contribute to saving energy and reducing CO2 at molding sites ![ホッパードライヤー「排気熱交換器」装着](https://eng.harmo-net.co.jp/hubfs/pic_sustainability_07.jpg "ホッパードライヤー「排気熱交換器」装着") Hopper dryer equipped with "insulation coat" In Hopper dryers, resin is inserted in a metal drum and is dried by heat generated by a heater, with heat dissipating into the surrounding environment. Wrapping a heat-insulating coat around the dryer prevents heat dissipation and contributes to energy saving. **Reduction in CO2 (daily) **3kwh x 0.379 = 1.137kg **→ Equivalent to the amount of CO2 emitted by a person in a day**** ** ![ホッパードライヤー「排気熱交換器」装着](https://eng.harmo-net.co.jp/hubfs/pic_sustainability_07.jpg "ホッパードライヤー「排気熱交換器」装着") Hopper dryer equipped with "exhaust heat exchanger" The hot air supplied to the hopper dryer, after passing through the drum, is naturally released indoors. Forcing the air that has passed through the cyclone back into the drum with the help of a heat exchanger contributes to reducing heat dissipation. **Reduction in CO2 (annual) **5,750kwh x 0.379 = 2,179kg **→Equivalent to the amount of CO2 absorbed by 142 cedar trees in one year** ![pic_sustainability_08](https://eng.harmo-net.co.jp/hubfs/pic_sustainability_08.jpg "pic_sustainability_08") **Reduction in CO2 (monthly) **324kwh x 0.379 = 122.8kg **→ Equivalent to the amount of CO2 emitted when driving between Yokohama and Lake Biwa by car**** ** ![生産工程での材料のムダ削減](https://eng.harmo-net.co.jp/hubfs/pic_sustainability_05.jpg "生産工程での材料のムダ削減") Total Link’s "Peripheral device shut off upon completion" feature The Total Link management system can automatically instruct peripheral devices to stop operating after the scheduled production target has been achieved and the robots have stopped. This reduces unnecessary operation and leads to energy saving. **Reduction in CO2 (annual) **1,469kwh x 0.379 = 557kg **→Equivalent to the amount of CO2 absorbed by 35 cedar trees in one year** SUSTAINABILITY Towards a sustainable society Four initiatives aimed at reducing the impact on environment #### 01. Use of RoHS Directive-compliant products The RoHS Directive is a standard introduced to facilitate the recycling of electrical and electronic equipment. It was established with the aim of excluding certain harmful substances to prevent them from affecting people and the environment and HARMO is committed to using products that comply with the RoHS Directive. #### 02. Thorough switch to LED in all our plants #### 03. Effective control of power consumption We have adopted a demand control system that allows us to visualize power consumption. Visualizing power consumption makes it possible to regulate the amount of power used in the course of operations and to eliminate wasteful power consumption. #### 04. Reduction of industrial waste We properly dispose of all industrial waste generated in the course of the manufacturing process. By curbing the discharge of industrial waste and properly sorting waste we are committed to promoting resource recycling. Going forward, HARMO will continue to strengthen its commitment to sustainability   ![マスクグループ 11483@2x (2)](https://eng.harmo-net.co.jp/hubfs/sustainability/%E3%83%9E%E3%82%B9%E3%82%AF%E3%82%B0%E3%83%AB%E3%83%BC%E3%83%97%2011483@2x%20(2).jpg "マスクグループ 11483@2x (2)")
