Used cooking oils are collected from onsite restaurants to be refined and converted to biodiesel fuel. This biodiesel blend is used in place of regular petroleum fuel throughout the facility for trams, buses, trucks, tractors and equipment.
Solid Waste Management, Reduction, Reuse and Recycling
Office supplies are reduced through e-mail, bulletin boards, double-sided copying, and reuse of file folders, envelopes, and scrap paper. Invoices and purchase orders are processed electronically to eliminate copying and mailing. Many warehouse supplies including cleaners, paper goods, electrolyte drinks, and drugs are purchased in bulk. Waste products such as office paper, corrugated cardboard, used motor oil, oil filters, tires, batteries, antifreeze, pallets, cooking grease, wood waste, and plastic six-pack rings are sorted for recycling. The composting center is surfaced with recycled coal fly ash and has processes manure, bedding, plant material, kitchen scraps, and corrugated cardboard. All compost is used onsite. A Randolph County Recycling Drop Site is located on the property for mixed paper, newspaper, metal cans, glass containers, and plastic bottles. Collection points are also set up for cell phones recycling, keeping toxic chemicals out of our environment, providing vital emergency services to those in need, and helping to support the education efforts of impoverished peoples of Uganda.
Freshwater Consumption Reduction
For exhibits, irrigation, and cleaning, 62 million gallons of water is used per year. Water for irrigation is mainly supplied from two on-site lakes. Meters were installed in 1996 to monitor water use and detect leaks. High pressure/low volume nozzles are used to clean animal areas.
Energy Efficiency, Conservation and Management
A biodiesel blend, collected from on-site restaurants, is used in place of regular petroleum fuel for trams, buses, trucks, tractors and equipment. Since 1998, a computerized energy management system has been used to control temperature and humidity in each building and exhibit. In the Education Center alone, the system has reduced electricity use by 40%. Rangers and other staff use bicycles for travel in the Park.
Picnic tables and recycling containers are made from recycled plastic as is decking used in renovation projects.
Training and Education for Employees and Clients
Information is available for individuals to learn more about what they can do to conserve resources. "Conservation Captains" meet once a month to find ways to reduce, reuse, and recycle waste materials. Decisions from these meetings are implemented park-wide.
