Solid Waste Management Process

1. Waste Generation and Composition

Solid waste in Mauritius is generated from households, commercial establishments, industries, and public spaces. The primary categories include:

• Organic Waste (food scraps, yard waste)
• Plastics and Packaging Waste
• Paper and Cardboard
• Metal and Glass
• E-waste (electronics)
• Hazardous and Medical Waste
• Construction and Demolition Waste

The per capita waste generation in Mauritius is approximately 1.2 kg per day, leading to an annual total of around 550,000 tons of municipal solid waste.

2. Waste Collection System

Waste collection is managed through a combination of municipal services and private contractors. The process involves:

• Household Collection – Regular door-to-door collection, primarily of general waste.
• Commercial and Industrial Collection – Larger waste generators (hotels, industries, shopping malls) have dedicated waste collection systems.
• Public Waste Bins and Litter Collection – Placed in high-footfall areas to reduce littering.
• Bulky Waste Collection – Specialized collection for furniture, appliances, and construction debris.

While formal waste collection covers over 90% of households, illegal dumping and littering remain issues in some areas.

3. Waste Transportation

Once collected, solid waste is transported to:

• Transfer Stations – Intermediate locations where waste is compacted to reduce transport costs.    (READ MORE..)
• Final Disposal Sites – The main landfill at Mare Chicose.   (READ MORE..)

Waste from Rodrigues Island and other remote regions is shipped to Mauritius for final disposal.

4. Waste Treatment and Processing

Mauritius has a limited recycling and treatment infrastructure; with  

4.1 Recycling and Recovery

• Plastics, Paper, Metal, and Glass – Collected by private recyclers for export.
• E-waste Processing – Handled by specialized recyclers who recover valuable metals.
• Organic Waste Processing – Limited composting initiatives exist, mainly for agricultural use.

4.2 Energy Recovery

 Waste-to-Energy Potential – Mauritius does not currently operate a waste-to-energy plant.
 Biogas from Landfills – Methane from Mare Chicose landfill is captured and used for electricity generation.

5. Final Disposal: The Mare Chicose Landfill

 (READ MORE..)

Mare Chicose is the only landfill in Mauritius, receiving over 1,500 tons of waste daily. It is an engineered landfill with:

• Leachate treatment systems to prevent groundwater contamination.
• Gas capture systems for methane extraction.
• Waste compacting to maximize landfill lifespan.

With Mauritius' increasing waste generation, Mare Chicose is expected to reach full capacity within the next decade, making alternative waste management solutions a top priority.

6. Challenges and Future Strategies

Key Challenges

• High dependency on landfilling – Over 95% of waste is landfilled.
• Low recycling rates – Recycling is not well-integrated into the national waste system.
• Limited public awareness – Many citizens lack knowledge about waste sorting and recycling.
• Illegal dumping and pollution – Open dumping is still practiced in some areas.

Future Strategies

• Expanding Recycling Initiatives – Improve infrastructure for plastic, paper, metal, and electronic waste recovery.
• Composting and Biogas Development – Encourage organic waste diversion from landfills.
• Waste-to-Energy Plants – Consider incineration or anaerobic digestion for sustainable energy recovery.
• Public Awareness Campaigns – Strengthen education on waste separation, composting, and recycling.
• Legislation for Waste Reduction – Implement policies such as plastic bans, extended producer responsibility (EPR), and landfill tax incentives.
