Establishment of a Recycling-Oriented Society

Waste Reduction Results in Fiscal 2019

The Eisai Group in Japan is working to achieve zero emissions, which involves reducing the ratio of waste sent to landfill to the amount of waste generated to 1% or less, and conducting waste disposal with three goals in mind; specifically, reduce the amount of waste generated, increase the amount of recycled waste and decrease the amount of waste sent to landfill. In fiscal 2019, we attained zero emissions for the 12th consecutive fiscal year. However, the amount of waste sent to landfill increased 5 tons, from 6 to 11 tons. This is largely attributable to the amount of construction materials sent to landfill by the Eisai Group in Japan, which increased 4 tons. 

Contrarily, the Kawashima Plant significantly reduced its waste generation after it peaked due to the disposal of old equipment and the construction of a new building. We also control the generation of waste relating to pharmaceutical products, and the amount of waste generated by the Eisai Group in Japan overall dropped 395 tons compared with the previous fiscal year. In addition, the Kashima Plant actively recycled waste solvent despite an increase in production. Consequently, the Eisai Group in Japan achieved a recycling rate (including valuables sold) of 53.7%, up 5.8% from the previous fiscal year. 

The impact of the recent restrictions on the importing of plastic waste in China and Southeast Asia has led to an increase in the amount of waste treated domestically, resulting in treatment delays due to the limited capacity of disposal contractors. While continuing to treat waste appropriately in compliance with related laws and regulations, we will continue to reduce and recycle waste and ensure the efficient use of resources as we pursue ways to contribute to the creation of a recycling-oriented society.

Initiative for Recycling Resources

In order to promote the establishment of a recycling-oriented society, it is essential to reduce the amount of waste generated in addition to reusing and recycling resources such as metal, glass, waste oil and paper products from waste. Based on this perspective, we actively promote the sale of equipment and devices for reuse as well as the recycling of plastics, scrap metal, glass bottles and waste oil. Also, to reduce the total amount of wastepaper, we are promoting the sale of wastepaper while avoiding generation of unnecessary waste by devising better ways to proceed with meetings and to copy documents. At the Kashima Plant, we have expanded the scope of our efforts to promote the sale of wastepaper in Japan from operational sites and the head office to include sales offices. We also continue to reuse organic solvents, such as those used in the manufacture of active pharmaceutical ingredients, and sell these as auxiliary fuel for waste oil.

Onsite Inspections of Waste-Processing Companies

The Eisai Group in Japan has been conducting regular onsite inspections of its waste disposal contractors. For the purpose of checking that waste is being disposed of properly, periodic inspections are carried out for contractors engaged in the collection, transport, intermediate processing and final disposal of waste. During fiscal 2019, a total of 30 onsite inspections were conducted by the Eisai Group in Japan at sites around the country, and it was confirmed that waste is being disposed of in an appropriate manner.

For potential new contractors, we conduct careful screening that includes onsite inspections with priority given to government-certified excellent industrial waste management contractors.
