Plastic to Biodiesel in Almería. Successfully turning marine plastic into biodiesel.
Published May 9, 2025 | Category: Nature & Environment
TL;DR: Plastic to biodiesel in Almería is no longer a theory—it’s a working model that turns sea waste into fuel, jobs, and sustainable change.
Plastic to Biodiesel in Almería: How a Small Port Leads Coastal Sustainability

Plastic to biodiesel in Almería is no longer an experiment. In the fishing port of Almería, a circular economy project is successfully turning marine plastic into biodiesel, powering fishing vessels and creating local jobs. Supported by the EU’s LIFE DREAM program, the initiative serves as a model of sustainability and local empowerment in the Mediterranean region.
From Trash to Fuel: How the Process Works
The concept behind plastic to biodiesel in Almería is elegantly simple. Fishermen collect plastic waste from the sea during their routine operations. Once brought ashore, the waste is sorted and prepared for processing in a mobile pyrolysis unit located in the port itself. Pyrolysis is a high-temperature, oxygen-free process that breaks down long-chain polymers into liquid hydrocarbons—producing clean, usable biodiesel fuel.
On average, each processing batch yields approximately 50 liters of biodiesel, depending on the composition of the plastic waste. This fuel is then reused directly by the local fishing fleet, completing a true circular loop. Instead of contributing to marine pollution, these fishermen are now literally fueling the future.
Why Pyrolysis Matters
Unlike incineration or landfill disposal, pyrolysis leaves behind minimal toxic residue and emits no harmful gases. It’s a low-emission technology suited for marine plastic waste, particularly useful in port areas where waste streams are complex and recycling rates are low. In Almería, the mobile unit has shown how scalable and efficient the system can be, especially for small or mid-sized coastal towns.
The biodiesel produced can be used in standard diesel engines, making it directly applicable to fishing vessels, port service boats, and even municipal vehicles. This versatility adds to the project’s sustainability value.
Community at the Core: Empowering Almería’s Fishermen
For the fishermen of Almería, this initiative offers more than just cleaner seas. It represents a shift in how their role is perceived—no longer just harvesters of marine life, they are now stewards of the ocean. Their direct involvement in waste recovery, energy production, and marine conservation is helping redefine the identity of coastal communities across southern Spain.
Local associations such as the Organización de Productores Pesqueros (OPP-71) have been instrumental in coordinating the effort. They provide logistical support, training, and promotion to ensure that fishermen feel invested in the process. The social transformation is as meaningful as the environmental impact.
Women Leading Innovation: The Role of Asociación Galatea
Back on land, women from Asociación Galatea play a crucial role in the second phase of the plastic to biodiesel cycle. They assist in sorting plastic waste for pyrolysis and repurpose leftover byproducts, such as paraffin.
From Waste to Warmth: Handmade Candles from Paraffin Byproducts

As part of the plastic to biodiesel initiative in Almería, local women transform paraffin byproducts into artisanal candles. These sustainable products reflect a deeper layer of the circular economy: nothing is wasted, and every element is repurposed with care, skill and community impact.
This economic participation not only supports household incomes but also enhances social inclusion and gender equity. Their work gives tangible form to the principles of a circular economy—where nothing is wasted, and value is extracted at every stage.
Environmental Impact: A Cleaner Sea and Lower Emissions
The ecological benefits of the project are already visible. Marine litter has decreased in targeted areas of the Alboran Sea, and net entanglements of plastic waste have been significantly reduced. Divers and marine biologists working in the area report healthier conditions for endemic species like the Mediterranean monk seal and seagrass meadows.
By replacing fossil fuels with locally produced biodiesel, the project also reduces the port’s overall carbon footprint. It contributes to national and European decarbonization goals while making maritime transport more resilient to fossil fuel price fluctuations.
Scaling Up: Can Almería’s Model Go Global?
Plastic to biodiesel in Almería has gained attention from other ports and coastal regions in Spain, Italy, and Greece. Its low-tech, high-impact model makes it highly adaptable to other fishing communities. The portability of the pyrolysis unit is a major strength—it doesn’t require large infrastructure or long-term investment to be effective.
The Blue Circular Economy network is currently working on documentation and policy proposals to integrate this approach into broader marine waste strategies across the EU. The LIFE DREAM project is expected to publish its first impact assessment later this year.
Educational and Economic Spin-Offs
Almería’s initiative has also opened new doors in education and tourism. Schools in the area now include site visits to the port as part of their sustainability curriculum. Local media and eco-tourism companies are organizing guided tours that showcase the biodiesel production process and artisan work by Asociación Galatea.
Workshops on plastic reuse, sustainable fishing, and marine ecology have also emerged—turning the port into a living classroom that teaches circularity in action. This outreach is crucial to building long-term awareness and ensuring generational continuity in environmental responsibility.
A Model of Hope and Pragmatism
Plastic to biodiesel in Almería is not just a local initiative—it’s a model of hope, built on practical, replicable methods. By connecting sea cleanup with energy generation, gender inclusion, and economic development, it redefines how small ports can lead big changes.
In a world where climate action often feels abstract, this project is tangible proof that sustainable transformation is possible—one fishing net, one candle, and one drop of biodiesel at a time.

Snow in Almeria: Calar Alto Turns White as Rain Reaches Much of the Province
Published December 1, 2025 | Category: Nature & Environment
TL;DR: Snow returned to the province on Sunday afternoon, covering Calar Alto in white and bringing steady rainfall to more than a dozen towns as cold winter air settled in.
Snow in Almeria Returns to Calar Alto as Widespread Rain Reaches Much of Almeria
Snow in Almeria made an early return this weekend as the highest peaks of the Sierra de los Filabres turned white once again. The Calar Alto area, home to one of Spain’s main high-altitude observatories, saw fresh snowfall on Sunday afternoon, marking one of the first notable winter episodes of the season.
At 2,168 metres above sea level, temperatures in Calar Alto dropped below zero, allowing snow to accumulate around the upper slopes and surrounding pine forests. The cold air mass has also brought a sharp temperature drop across inland municipalities, with places like Chirivel, Maria, Velez-Rubio and Velez-Blanco expected to fall close to 3ºC overnight.
Rainfall Across the Province
Alongside the snowfall, steady rain moved across a wide area of the province on Sunday. According to data from regional meteorological networks, Ohanes recorded the highest recent accumulation with nearly 6 litres per square metre in one hour. Felix also registered significant rainfall, followed closely by Canjayar and Abrucena.
In the western and central regions, towns such as Dalias, Enix, El Ejido and Roquetas de Mar measured between 3 and 4 litres per square metre during the afternoon. Lighter but continuous rainfall was also reported in Finana, Fondon, Illar, Vicar, La Mojonera, Alcolea and Berja.
Winter Conditions Settling In
With temperatures continuing to drop and rain spreading across much of the province, the transition into December is now clearly underway. More unsettled weather is expected in the coming days as the cold air mass remains over the region.

Junta Rejects New Camping Project in Cabo de Gata
Published November 28, 2025 | Category: Nature & Environment
TL;DR: The regional government has rejected a proposed camping with 42 bungalows in the Cabo de Gata-Nijar Natural Park because it was too close to an existing motorhome area.
Junta Blocks New Camping Project Near Cabo de Gata
A plan to build a camping complex with 42 bungalows in the La Joya area of Agua Amarga, inside the Cabo de Gata-Nijar Natural Park, has been rejected by the regional government. The project, which included reception facilities, a restaurant, bar, small supermarket and leisure areas, has been denied unified environmental authorisation.
According to the Junta de Andalucía, the project is incompatible with the current planning rules for the natural park. One of the key points is distance: any new tourist camping site in this zone must be located at least six kilometres away from another existing campsite.
In this case, there is already an authorised motorhome area in Agua Amarga, just one kilometre from the proposed site. Under the current tourism regulations, this motorhome area is officially classified as a tourist camping, which means the new project would not meet the required separation distance.
The decision effectively halts the development and sends a clear signal that new tourist accommodation inside protected areas will be strictly evaluated against existing facilities and environmental rules.

Palomares PA-4 urbanisation project: environmental risks, nuclear legacy and coastal regression
Published November 16, 2025 | Category: Infrastructure
TL;DR: The Palomares PA-4 urbanisation project — a plan for 1,600 homes and a hotel on a fragile coastal area — has received regional approval despite flood risks, ecosystem vulnerability, water pressure and proximity to Palomares’ radiological monitoring zone. Environmental groups warn that the project ignores long-term climate projections and coastal regression.

Overview
The PA-4 urbanisation sector in Palomares proposes the construction of 1,600 homes and a hotel next to Quitapellejos beach, in one of the most environmentally delicate zones of Cuevas del Almanzora. The regional environmental ruling, issued by the Junta de Andalucía, concludes that the project is “compatible” as long as extensive conditions are met.
Environmental groups argue the opposite, warning that the project could damage fragile coastal habitats, increase flood risks and add population pressure to an area already experiencing water constraints and coastal regression.
Nuclear context surrounding the Palomares PA-4 urbanisation project
The 1966 accident involving US thermonuclear bombs dispersed plutonium dust over several hectares of Palomares. Although partially cleaned, the area still maintains monitored land under the supervision of CIEMAT.
The PA-4 area sits just outside the radiological perimeter, but environmental groups highlight that the contaminated soil has never been fully removed, and future decontamination could be complicated by large-scale residential occupation.
A fragile ecosystem: coastal sand formations, vegetation and biodiversity
The project area contains low coastal sand formations, halophytic vegetation and habitat zones identified as environmentally sensitive. The Spanish ruling explicitly acknowledges the presence of dunas and habitats of community interest, even if these formations are not visually large dunes.
Ecologists warn that proposed “restoration” and “transplanting” measures are unreliable, as coastal sand systems depend on wind dynamics, sediment supply and storm patterns that cannot be artificially replicated.
Water pressure and desalination dependency in Levante Almeriense
Over the past decade, water supply for Levante Almeriense has required emergency interventions. The region depends heavily on the Galasa network and the Carboneras desalination plant. The Junta accepts existing certificates but environmental groups argue that adding an estimated 4,000 new residents increases long-term vulnerability given past shortages and infrastructure failures.
Flood zones, sea-level rise and coastal regression
The Ministerio para la Transición Ecológica (MITECO) identifies the Quitapellejos sector as an area experiencing:
- coastal regression,
- stronger seasonal storms,
- low land elevation,
- increasing exposure due to climate change.
The original planning documents proposed channelling rainwater through streets towards the shoreline—an approach ecologists consider unacceptable under modern coastal-risk standards.
Urban planning timeline: an old licence in a new climate reality
The PA-4 sector holds longstanding urbanisation rights dating back decades. This older licence underpins the current project, despite being drafted in a period without today’s climate science, sea-level projections or updated coastal protection laws.
Environmental organisations argue that inactivity over such a long time should invalidate the licence; however, the Junta has not questioned its validity.
The municipal position and the political dimension
The Ayuntamiento de Cuevas del Almanzora supports the project, citing a lack of hotel beds, economic benefits and competition with neighbouring coastal towns. The position has remained consistent across political parties.
Environmental groups counter that PA-4 is the wrong location for high-density development due to flood risks, ecosystem fragility and the still-unresolved radiological legacy.
Comparisons with Mojácar, Vera Playa and Terreros
Supporters compare the project to existing developed areas such as Mojácar and Vera Playa. Ecologists argue that these comparisons ignore fundamental differences:
- Mojácar has a longer and more stable coastline.
- Vera Playa was urbanised before modern regulations.
- Terreros shows the risk of speculative projects that leave unfinished streets and infrastructure.
Tourism, hotel capacity and economic expectations
Cuevas del Almanzora lacks hotel accommodation, and supporters argue a new hotel could stimulate tourism. However, ecologists warn that:
- Water demand will increase.
- Sewage systems depending on pumping stations are vulnerable to storms.
- Flood-exposed coastal real estate may be risky long-term.
Conclusion
The approval of the Palomares PA-4 urbanisation project highlights the ongoing tension between economic development and environmental protection along Almeria’s fragile coastline. While technically allowed under strict conditions, the combined risks — coastal regression, flood exposure, ecosystem fragility and proximity to monitored nuclear-contaminated land — raise questions about its long-term sustainability.

Las Negras Cleanup This Sunday: Volunteers Join Níjar Town Hall in Cabo de Gata
Published November 2025 | Category: Nature & Environment
TL;DR: This Sunday, Las Negras hosts a community cleanup with international volunteers, supported by the Níjar Town Hall and funded through the EU’s European Solidarity Corps.
Las Negras cleanup this Sunday: volunteers unite to protect Cabo de Gata–Níjar Natural Park
The village of Las Negras will host a community cleanup this Sunday, 16 November, bringing together the Níjar Town Hall and an international team of volunteers. The event aims to protect one of the most environmentally sensitive areas of the Cabo de Gata–Níjar Natural Park while raising awareness among residents and visitors.
Overview
The activity is part of a month-long programme funded by the European Solidarity Corps (ESC), which brings young volunteers from across Europe to collaborate on environmental initiatives in the Níjar municipality. The volunteers are currently based in Fernán Pérez and are participating in coastal cleanups, neighbourhood maintenance and environmental workshops in local schools.
Event details
Date: Sunday, 16 November 2025
Start time: 09:00
Meeting point: Las Negras roundabout
The cleanup will focus on the village entrance, the beach area and the dry riverbed. All tools and materials — including gloves and bags — will be provided by the organisers. Residents and visitors interested in joining can contact the coordination team at +39 320 063 8535.
Environmental context
The initiative comes after a summer in which the Níjar Town Hall removed more than seven tons of waste from popular beaches such as Agua Amarga and San José. During the high season, the Natural Park faces intense visitor pressure: nearly 50,000 vehicles passed through the controlled access points to Mónsul, Barronal and Genoveses between June and September.
Local authorities highlight that community-led activities like this one help mitigate seasonal impact while strengthening environmental stewardship throughout the year.
