Otsuka Pharmaceutical Begins Rollout of PET Bottles Made from 100% Recycled PET Resin
Aiming to Realize a Decarbonized and Circular Society
Otsuka Pharmaceutical Co., Ltd. (Otsuka) will begin a nationwide rollout of PET bottle containers made from 100% recycled PET resin*1 from late January this year. As a result, more than 90% (by number of bottles) of the company's PET bottle beverage products will use containers made entirely from recycled PET resin*2. This initiative is expected to reduce greenhouse gas (GHG) emissions by approximately 5,300 tons*2. Otsuka will continue to promote environmentally conscious and sustainable initiatives toward the realization of a decarbonized, circular society.

Additionally, to promote bottle-to-bottle*3 horizontal recycling, using collected PET bottles as raw materials for new PET bottles, the company has concluded resource-circulation agreements with 30 local governments*4 nationwide in Japan, including Tokushima Prefecture, where the Otsuka group originated.

Otsuka operates its business based on a corporate philosophy centered on contributing to health. In line with this mission, the company has identified four key material issues (materiality) and is actively working to address them while striving to realize a sustainable society.
Under "Reducing Environmental Impact," one of Otsuka group's material issues, Otsuka is advancing initiatives aimed at achieving carbon neutrality by mitigating climate change caused by global warming. Efforts include the introduction of CO₂-free electricity, installation of solar power systems, the utilization of renewable energy, and maximizing energy efficiency.
In addition, based on the Otsuka Group Plastics Statement, the company is promoting the "Circular Economy" by reducing resource use and advancing circular utilization. Recognizing the use of fossil resource-derived materials and the discharge of waste into nature as environmental burdens to be eliminated, the company promotes bottle-to-bottle recycling, expands the use of PET bottles made from recycled PET resin and label-free bottles, and pursues container lightweighting and the adoption of alternative materials. Otsuka also enhances resource efficiency across the entire value chain, from raw material procurement to manufacturing, logistics, and sales, while aiming to build a sustainable coexistence relationship with resources, including biological resources.
