Core Viewpoint - Jiangsu Nanjing Hongshan Forest Zoo is actively exploring green carbon reduction and striving for low-carbon and sustainable development through various initiatives [1][6]. Waste Management and Recycling - The zoo processes solid waste, including fallen leaves, animal waste, and visitor trash, to produce organic fertilizer, which is used for soil improvement and animal feed [2][3]. - The zoo generates approximately 2 cubic meters of garden waste daily, which is repurposed into animal bedding and organic fertilizer through a fermentation process [2][3]. Water Resource Management - The zoo incorporates water conservation strategies, such as permeable pathways that allow rainwater to infiltrate and replenish groundwater, thereby maintaining soil moisture and supporting local ecosystems [4][5]. - The design of the zoo aims to minimize human intervention and create a natural ecosystem, emphasizing the importance of water in sustaining biodiversity [4][5]. Renewable Energy Initiatives - The zoo has installed solar photovoltaic panels, generating over 80,000 kWh of green electricity annually, which significantly reduces carbon emissions by approximately 60.8 tons [6]. - A "zero-carbon" coffee machine in the zoo utilizes locally sourced ingredients and solar power, demonstrating the zoo's commitment to sustainability [5][6]. Overall Sustainability Goals - The zoo aims to achieve zero waste and promote resource recycling and energy conservation, serving as a model for urban waste management and sustainable practices [6].
