Green & Sustainability
Committed To Sustainability
The Green Mark certification scheme was launched in January 2005 as a green building rating system aimed at assessing a building’s environmental impact and performance. It offers a comprehensive framework for evaluating both new and existing buildings, promoting sustainable design and best practices in construction and operations.
Uni-drive supports the Green Mark certification, a sustainable building rating system launched in 2005, which evaluates a building’s environmental impact. By providing energy-efficient solutions in mechanical power transmission, engineering services, and ACMV systems, we help clients meet green building standards. Our ongoing commitment to sustainability drives us to offer innovative solutions that reduce environmental impact and promote sustainable construction practices.

What Do We Do for Sustainability
What do we do for renewable energy
Providing turnkey energy solutions across Asia Pacific, helping businesses save costs and reduce CO2 emissions by recovering and repurposing waste energy for heating or cooling. Our systems achieve up to 90% thermal energy savings by recycling wasted heat—like heat from carparks or air conditioning compressors—and using it for heating water, pools, or other applications at no extra cost. These solutions significantly lower energy use, are cost-effective, and can be retrofitted into existing buildings or integrated into new developments. We provide comprehensive solutions encompassing design, equipment supply, system integration, and installation—all under one roof for a seamless, one-stop solution.

Why Rainwater Harvesting
Multiple Benefits of Rainwater Harvesting:
1
Rainwater harvesting systems are less expensive, simple to install, operate, and maintain.
2
Rainwater harvesting systems can be adopted by individuals.
3
Reduces in the soil erosion and avoid the risk of flooding of roads.
4
Rainwater saves potable water usage for other purposes such as washing and in the toilet, watering garden and etc.
5
It is ideal for both residential and commercial properties.
6
It is an ideal solution to water problems especially in the areas with low water level It can provide an excellent back-up source of water for emergencies.
7
Effective way of saving of energy for pumping of ground water which leads to reduced water bills
Food Waste Recycling for Hotels: A Sustainable Approach
Design and Implementation of Pipe Systems for Food Waste Digesters in Hotels
1. Key Considerations for Pipe System Design
- Use durable, corrosion-resistant materials such as stainless steel, HDPE (high-density polyethylene), or PVC pipes to handle organic waste without degradation.
- Ensure the material can withstand high temperatures if the system involves hot water flushing or pre-treatment processes.
- Choose an appropriate pipe diameter based on the volume of food waste generated. For most hotels, 4-inch to 6-inch pipes are sufficient.
- Maintain a slope of 1-2% (1-2 cm per meter) to ensure smooth gravity flow and prevent clogging.
- Install access points (e.g., cleanout ports, inspection hatches) at regular intervals to facilitate maintenance and unclogging.
- Ensure the pipe system is easily accessible for repairs without disrupting hotel operations.
- Incorporate airtight seals and ventilation systems to minimize odors.
- Use deodorizing agents or biofilters at key points to neutralize unpleasant smells.
- Plan the pipe layout to integrate seamlessly with existing plumbing systems while avoiding interference with other utilities (e.g., water, electrical lines).
- Route pipes through service corridors or non-public areas to maintain aesthetics.
2. Step-by-Step Installation Process
- Conduct a thorough assessment of the hotel’s layout to identify optimal locations for food waste collection points, pipe routes, and the digester unit.
- Consider proximity to kitchens, dining areas, and waste storage zones to minimize pipe length and complexity.
- Create a detailed piping diagram showing the route from collection points to the digester, including slopes, access points, and connections.
- Use CAD software or 3D modeling tools to visualize the system and ensure compatibility with the hotel’s structure.
- Begin by installing the main pipeline from the digester to the central collection point.
- Branch out to individual collection points (e.g., kitchen sinks, food waste bins) using smaller-diameter pipes.
- Secure pipes firmly to walls or ceilings using brackets to prevent sagging or movement.
- Conduct a pressure test to check for leaks and ensure the system is airtight.
- Perform a trial run with water or simulated food waste to verify flow and identify potential blockages.
3. Features to Enhance Efficiency
- Integrate a water flushing mechanism to periodically clean the pipes and prevent buildup of sticky or solid waste.
- Use recycled water from the hotel’s greywater system to conserve resources.
- Install in-line grinders at key points to break down large food particles into smaller pieces, reducing the risk of clogs.
- Equip the pipe system with sensors to monitor flow rates, detect blockages, and track waste volumes in real time.
- Connect sensors to a centralized dashboard for easy monitoring and troubleshooting.
4. Maintenance Best Practices
- Schedule routine cleaning of the pipe system using high-pressure water jets or enzymatic cleaners to remove grease and residue.
- Conduct quarterly inspections of pipes, joints, and access points to identify and address potential issues early.
- Train hotel staff on proper use of the system, including how to segregate food waste and avoid introducing non-organic materials (e.g., plastics, cutlery) into the pipes.
5. Benefits of a Well-Designed Pipe System
- Ensures smooth and reliable transport of food waste to the digester, minimizing disruptions to hotel operations.
- Reduces labor costs associated with manual waste handling and minimizes the risk of costly repairs due to blockages or leaks.
- Supports the hotel’s sustainability goals by enabling efficient recycling of food waste into biogas and compost.
- Maintains a clean and odor-free environment, enhancing guest satisfaction and reinforcing the hotel’s commitment to eco-friendly practices.
6. Example Layout for a Hotel
- Kitchen prep areas
- Buffet stations
- Dishwashing areas
- Main pipeline runs from the basement (digester location) to the ground floor.
- Smaller branch lines connect kitchens and dining areas to the main pipeline.
- Place the digester in a dedicated utility room or outdoor area with proper ventilation and drainage.

Enhancing Sustainability with Energy-Efficient ACMV Systems
Energy-efficient Air Conditioning and Mechanical Ventilation (ACMV) systems are key to reducing energy consumption and carbon emissions in buildings. By integrating high-efficiency chillers, variable speed drives (VSDs), smart controls, and optimised ducting layouts, these systems deliver reliable climate control while minimising environmental impact.
Proper design, regular maintenance, and performance monitoring further enhance ACMV efficiency—helping facilities meet green building standards such as BCA Green Mark. Investing in sustainable ACMV solutions not only lowers utility costs but also supports long-term environmental goals for greener, smarter buildings.
