Portugal to Build Waste-to-Energy Plant as Algarve Landfills Hit Limit

Algarve’s Landfills Near Capacity, Minister Pushes Waste-to-Energy Solution

The Algarve region’s two landfills, in Loulé and Portimão, have just 18 to 24 months of space remaining. Environment and Energy Minister Maria da Graça Carvalho announced this week that the Portuguese Environment Agency (APA) will launch a public tender on 15 October to study the technical solution, location, and eventually build a unit for the energy recovery of waste.

The region produces around 400,000 tonnes of waste each year and sends 85% of it to landfill, a share that has actually risen from 80% in recent years and sits far above the national average of 56% and the EU’s 2035 target of 10%. The minister attributed the high per-capita waste generation to tourism—visitors are not counted in official population statistics but add significantly to the waste stream—and noted that total waste volumes have grown 13% over the past four years.

While short-term expansion of both landfills will add about seven and a half years of capacity (carrying the region until 2034–2035), the permanent solution must be a facility that recovers energy from waste, in line with EU funding opportunities and in coordination with the 16 municipalities of the Algarve Intermunicipal Community (AMAL).

“It is not sound policy to build more landfills when we need to reduce to 10% and we are at 85%,” Carvalho said, stressing that the project must be “accepted by the population, so it doesn’t create problems later for the construction.” The minister pointed to the availability of European funds and the need for a definitive fix to maintain the region’s quality of tourism and life.

What’s Driving the Urgent Shift from Landfill to Energy Recovery

A Region Addicted to Landfill

The Algarve’s waste habits are startling. With a landfilling rate of 85%, the region is not only far behind the rest of Portugal (56%) but is moving in the wrong direction—the figure was 80% recently. The root cause is a structural mismatch: booming tourism drives waste generation, but the region’s permanent population, used for national and EU per-capita metrics, hides the true load. This makes it one of Europe’s worst performers in waste diversion and puts pressure on the two aging landfills.

The EU Regulatory Hammer

EU waste directives require member states to reduce municipal waste going to landfill to 10% by 2035. The Algarve’s current performance, if left unaddressed, would invite infringement proceedings and potential fines. The new waste-to-energy plant is therefore not merely an environmental choice—it is a compliance necessity. With EU funds available for the transition, the Portuguese government is leaning on financial incentives to accelerate a shift that would otherwise be politically and economically painful for the region.

Technology and Funding: What’s on the Table

The minister strongly signaled that the solution will involve energy valorisation of waste—effectively incineration with power generation. The tender launched on 15 October will study both the technical feasibility and the siting, following a model similar to the one used for the Algarve’s desalination plant, where location studies were done in close collaboration with local mayors. That ensures the final choice carries political buy-in and reduces the risk of later legal challenges. The commitment to EU co-financing is central: without external support, the financial burden on municipalities would be very high.

The Local Politics of a Waste Plant

Carvalho’s emphasis on public acceptance is a clear nod to the political difficulty of siting any waste treatment facility. Previous infrastructure projects in Portugal have faced years of local resistance. By involving the 16 municipalities from the start and mimicking the desalination plant’s consultation methodology, the government hopes to pre-empt “not in my backyard” opposition. The timeline is tight: the two-year landfill runway leaves little room for prolonged disputes. Success will depend on how well the technical options—and the economic benefits, such as energy revenue and EU funds—are communicated to residents.

What the October Tender Means for Municipalities and the Waste Sector

• For municipalities and the waste management industry: The 15 October tender will define the technical scope and the site. Companies active in waste-to-energy engineering, construction, and operations should prepare to bid, as the project will likely be the largest environmental infrastructure contract in the Algarve for years. The coordination with AMAL suggests the eventual concession could involve municipal participation or guarantees.
• For EU fund coordination: The Algarve’s eligibility for European co-financing depends on alignment with circular-economy objectives. Meeting the 10% landfill target by 2035 is non-negotiable for continued funding; project sponsors must ensure the environmental impact assessment and design convincingly demonstrate diversion from landfill.
• For residents and businesses facing waste fees: The short-term cell expansions provide up to seven years of breathing room, but a permanent facility will be needed from the mid-2030s. Expect a lengthy consultation process that could delay final approvals—the government’s pledge to secure public acceptance signals that opposition may slow the timeline. Waste-collection fees could adjust as the region transitions away from cheap landfilling, but details remain unknown until the tender results are published.
