Why Islands Face Bigger Waste Problems
Small Island Developing States (SIDS) have big waste problems. They often import most of what they consume and have limited space to store what’s left behind. Trash piles up fast. Shipping it out costs a lot. Landfills take up valuable land. Recycling options are scarce.
The average person in the Caribbean produces 1.4 kilograms of solid waste each day. That’s 40% more than the global average. But most of that ends up in open dumps, burned, or polluting waterways. A 2021 study showed that over 80% of waste in SIDS is either landfilled or unmanaged.
Coastal communities also face rising sea levels, storms, and flooding. These make poorly built waste systems break down even faster.
Why “Big City” Solutions Don’t Work
Many waste systems are copied from large cities. But those models don’t work on small islands. A mega-landfill in New York won’t teach much to an island with only 30,000 residents and one garbage truck.
Roger E. Merritt Jr., learned this firsthand during his time as the Executive Director for the Waste Management Authority in the U.S. Virgin Islands. “People think you can just manage waste with cookie-cutter approaches used on the mainland and it’ll work,” he said. “But we had hurricanes, limited resources, and power outages. It’s a whole different game.”
SIDS need infrastructure scaled to their size, geography, and budget. That means smarter systems, not bigger ones.
What “Smarter” Looks Like in Action
Waste Segregation at the Source
One big improvement is getting people to separate waste before collection. Instead of dumping everything into one bin, homes can use separate containers for recyclables, food waste, and landfill items.
In Barbados, a small pilot for home composting reduced organic waste by 30% in some districts. That’s waste that no longer fills up landfills or rots in the heat.
Regional Cooperation
SIDS can work together by creating regional recycling hubs. For example, instead of every island trying to build its own materials recycling facility, one larger island can host a shared facility. Smaller islands send recyclable materials by boat on a shared schedule.
The Organisation of Eastern Caribbean States (OECS) has explored this idea, especially for glass and plastic. If done correctly, it lowers costs and increases recycling rates.
Building for Disasters
SIDS face hurricanes, earthquakes, and volcanic activity. Waste infrastructure must be built with this in mind.
Storms can break down old landfills and spread toxins. Floods can wash away stored waste. In the U.S. Virgin Islands, Merritt had to respond after hurricanes damaged collection routes and knocked out communications. “You can’t wait for ideal conditions,” he said. “You need a plan that works when things go wrong.”
Recommendations:
- Use storm-resistant designs for storage facilities
- Build flood protection around landfills and compost sites
- Identify and maintain Disaster Management Sites
- Train staff in emergency response plans that include waste
- Pre-position mobile units that can operate off-grid
How to Fund Smarter Waste Systems
Money is often the biggest roadblock. But there are ways to move forward.
Public–Private Partnerships
Governments can team up with companies to build and manage waste facilities. The private company invests in the equipment. The government helps with land, policy, and oversight.
This spreads out the cost and brings in technical knowledge. But it needs clear contracts and community buy-in to work well.
Tourism Taxes
Tourists create more waste than residents. Adding an “environmental tourism” fee to hotel bookings or cruise visits can raise money for waste upgrades. Some islands like the Maldives already do this.
Even $1 per visitor could raise millions per year for a small island.
International Support
Global funds like the Green Climate Fund or the Global Environment Facility offer grants to support sustainable waste systems. These grants can help islands install composting systems, train staff, or buy waste collection vehicles and landfill equipment.
But governments must plan carefully and show they can manage the projects.
Get the Community Involved
The best infrastructure won’t work without people’s support. Community education is key.
In the Marshall Islands, one recycling programme failed because no one sorted their waste. But a similar effort in Palau worked after local leaders helped spread the word.
Recommended steps:
- Hire local “waste champions” to teach sorting and composting
- Use schools to help build good habits early
- Offer rewards or discounts for clean recycling
- Set clear rules—and enforce them
Measure What Matters
Many SIDS don’t track waste data well. That makes planning harder.
Recommended metrics to track:
- How much waste is collected daily, monthly, and annually
- How much is recycled or composted
- Composition of the waste stream (Waste Characterization Study)
- Number of people trained in waste handling
- Solid waste collection vehicles and landfill equipment required
- Landfill Airspace Utilization (Compaction study to help determine remaining life)
Collecting this data helps leaders make better decisions. It also makes it easier to apply for grants and funding.
Waste isn’t just a cleanup problem—it’s a planning problem. On small islands, every decision counts. Land is limited. Storms are stronger. Money is tighter. That’s why smart, simple, and locally-made solutions work best.
People like Roger E. Merritt Jr., shows that progress doesn’t always need new tech or big budgets. Sometimes, it just needs listening to locals, working with what you’ve got, and planning for the next storm—not the last one.
“If you can’t make it work on a rainy day, it’s not a real solution,” Merritt said.
SIDS don’t need to follow big cities. They need to lead in their own way—with smarter plans, stronger communities, and systems that fit the islands they serve.
