We embrace sustainable best practices to reduce our impact on the environment and work towards a carbon neutral Mandai by 2024 through:
- Resource Stewardship
- Responsible Procurement
- Sustainable Design
- Upgrading of aging equipment to more energy efficient ones, for e.g the upgrade of the filtration system at the Zoo Pygmy Hippo Exhibit and that at the sewer pump station are projected to save 46,643 kWh /year.
- Modifications to wet moat circulation pumps operation for Zoo and Night Safari for e.g. the installation of digital timers to run at alternate hours, with projected savings of 54,676 kWh /year. We also continued to explore the use of solar-powered pumps.
- Building of two wastewater recycling plants that are expected to meet 21% of our precinct’s future water needs
Recycling of horticultural waste into mulch for planting beds and animal bedding. Some 30 back-of-house animal care areas for care are using the bedding
- Facilitating download for digital park maps to replace some 149,000 printed park maps distributed each month
- Black soldier fly and blue worm upcycling of animal food waste
- Catered facilities for Horticulture waste recycling (for new parks)
- Provisions for Food Waste Composters (for new parks)
Rainwater harvesting features are implemented in developing parks where feasible and are projected to meet 5% of the precinct's water needs. We are exploring the feasibility of capturing rainwater on-site in existing parks to decrease potable water usage.
Recycling Of Wastewater
The newly commissioned Mandai Wildlife Reserve wastewater Recycling Plants will soon start recycling wastewater from cleaning of animal dens and other back-of-house activities. We can expect 21% of the precinct’s future water needs to be met by this blackwater recycling.
Manatee Water Recovery System
Each manatee’s food intake is 350 – 600kg a day, with an output to match. To keep the water in the manatee’s habitat at River Wonders clean while optimising water usage, wastewater from the tank is not directly discharged but cycled through a bio bed filter.
Specially selected plants such as pandan and alligator-flag are grown in the bio bed to remove contaminants in the water. Besides improving water quality, the alligator-flag attracts bees and dragonflies and provides natural shelter for them.
This water recovery system recycles around 30,000m3 of water, which is 50% of our annual water savings.
Green procurement is an integral part of our sustainable operations, not only to lighten carbon footprint but also to influence the supply chain for sustainable products. Launched in June 2019, our Green Procurement Policy provides detailed guidance to business users on sustainable buying and exemplifies our preference for responsibly sourced products. As far as possible, we incorporate sustainability requirements in tender specifications.
Sustainable Procurement Roadmaps were developed based on top spends and environmental impact to guide our procurement. Palm oil, wood-based products and seafood are among goods that must be sustainably sourced.
All palm oil used in our kitchens is certified sustainable. 100% of seafood served at our F&B outlets are sustainably sourced. Beef is not featured on our F&B menu because of its disproportionately high environmental impact. We are working towards sustainable sourcing of other products such as animal feed and apparel.
We design our parks to holistically and seamlessly integrate with the natural environment.
