Sustainability / Materiality
As a renewable energy company, our relationship with the environment is an essential part of our corporate identity and license to operate. When constructing and operating our sites we strive for minimal disturbance of the local environment. We actively promote energy efficiency, and where possible, aim to contribute to a circular economy by promoting efficient use of natural resources, including recycling of materials. Efficient use of natural resources and energy not only reduces operational costs but also helps us to minimize our overall risk exposure to legal, regulatory, and reputational risks related to environmental issues.
JRE is undertaking several initiatives to reduce our environmental impact throughout the entire value chain, from project development to construction and operations.
During the project development phase that spans about 3-4 years before construction starts, as per legal requirements, JRE conducts robust environmental impact assessments to identify and mitigate the environmental risks associated with new developments. Impacts assessed include noise impacts and impacts on the natural environment such as on local bird habitats. JRE also cooperates with environmental non-profit organizations (NPO) and academics, who provide external input into our project plans to avoid impacting the nesting of wild birds in their surrounding natural habitat.
After careful planning, we strive to minimize our environmental impact during construction. For instance, JRE has put in place water quality monitoring systems to preserve local water quality and has built artificial ponds to prevent floods in the areas surrounding solar PV power plants.
During operation, we seek to recycle the main waste products generated by our sites, namely waste oil from wind farms and broken solar panels from solar power plants.
Our biomass power plant exclusively utilizes as fuel local wood chips (recycled from construction waste and made from forest residue and unused timber), which are supplied by Eco Green Holdings Co., Ltd. (JRE Group company) to generate electricity. The power plant is equipped with the system which enables to use biofuels efficiently and adequately satisfies the standards based on the laws for soot, smoke and wastewater. Not only waste but also burned ash are recycled as much as possible. JRE and its group companies realize cyclical and efficient use of local resources and mitigation of environmental impact.
