Good morning. Today brings curious science, a European spotlight on Porto and plenty of work on water across the country, with a few small, human stories to finish.

Curious science

Coimbra researchers detect electrical signals from marine microalgae

Researchers at the University of Coimbra's Faculty of Sciences and Technology have developed a technology that detects and analyses electrical signals produced by populations of marine microalgae. Using a porous 3D electrode with very low electrical impedance, the team found that living cells significantly alter recorded electrical fluctuations, and that these patterns change with microalgae concentration. The findings suggest electrochemical 'noise' can carry information about biological activity. The approach, tested on the model organism Phaeodactylum tricornutum, could lead to new monitoring tools for aquatic ecology, aquaculture, water quality and bioelectrochemical systems.

Controlling Varroa mites cuts virus spread among pollinators

A study found that controlling the Varroa destructor mite in honeybee colonies reduces levels of deformed wing virus (DWV) both in bees and in the flowers they visit. Keeping mite infestations at recommended thresholds cut the virus's presence on flowers by more than 35%. Wild pollinators such as bumblebees and hoverflies showed infection reductions of between 39% and 85% in areas with effective Varroa control, suggesting flowers act as a transmission route between species. The researchers warn that viruses linked to honeybees are spreading across many insect species and call for further study of the long-term effects.

University identifies offshore CO2 storage site off Figueira da Foz

The University of Évora has identified a reservoir in Portuguese offshore waters, about 22 kilometres off Figueira da Foz, suitable for testing geological CO2 storage. Located in the Lusitanian Basin in sandstone formations roughly 1,200 metres below sea level, it could hold over 93 million tonnes of CO2, though the pilot project aims to inject under 100,000 tonnes. Developed under the PilotSTRATEGY project with Galp and ICS-Lisbon, the plan foresees seismic surveys in 2027-2028, a well drilled in 2030, and an experimental injection in 2031-2032 using CO2 captured at the Souselas cement plant. Estimated cost is around 98 million euros.

Nature and landscape

Porto shortlisted for European Green Capital 2028

Porto is one of five finalists for the European Green Capital 2028 title, while Estarreja is competing for the European Green Leaf award for smaller cities. Winners will be announced on 8 October in Guimarães, the 2026 Green Capital. The European Commission's awards recognise measurable environmental progress alongside improved quality of life for residents. Porto scored strongly across all sustainability areas, particularly water management and climate adaptation. Porto competes against Aalborg, Bielsko-Biała, Košice and Saragoça, while Estarreja faces Benidorm and Chiclana de la Frontera. Winners receive €600,000 or €200,000 respectively to fund environmental projects.

Algarvensis Geopark wins national geoconservation award

The Algarvensis UNESCO Global Geopark, spanning Loulé, Silves and Albufeira, has won the Geoconservation Prize 2026 from Portugal's ProGEO group, shared ex aequo with the municipality of Montemor-o-Novo. The jury praised the consistency and scope of Algarvensis's integrated territorial management strategy for protecting and promoting geological heritage. Three candidacies were submitted, including one from Baião. The award, announced on International Geodiversity Day, follows shortly after Algarvensis gained UNESCO Global Geopark status. A ceremony will be held at a date and location still to be arranged.

PAN/Azores proposes regional strategy to protect Sargasso Sea

The PAN party's Azores branch has called on the Regional Government to develop a dedicated strategy to protect the Sargasso Sea, tying the move to the implementation of the international High Seas Biodiversity Agreement. Proposals include seeking protected-area status for the region, strengthening cooperation with the state, the EU and international partners, boosting the Azores' presence in relevant forums, and setting up a regional scientific working group. PAN also wants awareness campaigns and an assessment of ecological links between the Azores' marine protected area network and wider North Atlantic high-seas ecosystems. The party cites the Azores' 2023 deep-sea mining moratorium as precedent.

Farmers' group reports two wolf attacks near homes in Minho

The UPGALL farmers' organisation has reported two alleged Iberian wolf attacks within less than a week in Ponte da Barca and Ponte de Lima, killing two animals and injuring another. The first, on 30 September in Lindoso, killed a garrano horse less than 500 metres from houses. The second, on 6 October in Vitorino de Piães, killed a sheep and injured another inside a fenced, residential area. UPGALL says these add to other attacks across northern Portugal and is calling on authorities to monitor the cases, stressing the role of livestock farming in preserving native breeds and rural landscapes.

Needs attention

Residents report mass fish deaths in Condeixa-a-Nova river

Residents of Moinho da Palha, in Sebal Grande, Condeixa-a-Nova, reported dark, foul-smelling, foamy water in the Caldeirão river, along with dozens of dead or dying fish. Authorities were called to the scene and collected water samples for analysis. The incident is being described locally as an environmental crime, though the cause has not yet been established.

Environmental groups warn two data centres could drain Tejo River

Quercus and proTEJO are raising alarm over two mega data centres planned for Abrantes, by Hyperion and EDC ONE, citing risks to water availability, energy use, land occupation and heat islands. proTEJO estimates combined water consumption at full capacity could reach up to 22.2 million litres daily and energy use of 4,380 GWh yearly, nearly 29 times Abrantes' municipal consumption. Both groups demand a joint environmental impact study, binding efficiency limits, and public disclosure of cooling technology and water use. They also call for local residents in Alvega and Concavada to be consulted, warning the projects coincide with forecast water scarcity in the Tejo basin between 2028 and 2033.

Dozens protest industrial and tourism growth in Sines

A protest organised by the 'Hands Off the Alentejo Coast' platform gathered dozens of people in Sines on a national holiday. The platform unites 13 movements and associations from Grândola, Alcácer do Sal, Santiago do Cacém, Sines and Odemira. Demonstrators told SIC that expanding industry and luxury tourism and real estate are putting growing pressure on the region, and accused the government of ignoring local communities. Placards also criticised the management of the energy transition, with claims that Alentejo's resources are being exploited for foreign multinationals' benefit. Organisers describe it as one of many such protests emerging across Portugal.

ZERO urges mechanical-biological waste treatment, opposes incineration in Algarve

Environmental association ZERO has called for strengthened mechanical and biological treatment of urban waste in the Algarve, to stop biodegradable matter reaching landfill untreated. It wants domestic waste separated from that produced by economic activities, a measure it says is not being properly applied. ZERO proposes expanding Algar's two existing treatment units rather than building new facilities or investing in incineration. It also criticises Algar's waste action plan for leaving some 70,000 tonnes untreated, noting that a regional environmental authority's assessment of a new landfill cell in Loulé warns that depositing unstabilised organic waste is illegal.

EU report says farming uses 86% of Portugal's water

A European Commission document on Portugal's water management, using 2018 data, finds agriculture accounts for 86% of water consumption, far ahead of public supply (10.4%) and industry (3.6%). The sector drives 69% of pressure on groundwater and pollution linked to farming affects 36% of surface water bodies. Portugal still relies on estimates rather than direct measurement to track agricultural water withdrawals. The Commission also flags sharp regional disparities, with water stress reaching 91% in the Guadiana basin in summer, and recommends revising water pricing, since agriculture pays a much lower rate than public supply.

EU right-to-repair rules take effect, but Portugal misses deadline

New EU rules under the 'right to repair' directive aim to make fixing appliances like washing machines, vacuum cleaners and phones easier and more appealing than replacing them. Manufacturers may be required to repair covered products at a reasonable price and within a reasonable time, must share clear information on repair services, and cannot block independent repairers from using compatible parts. Choosing repair over replacement during a seller's warranty period extends that protection by at least 12 months. EU states had until 31 July 2026 to transpose the directive, but Portugal has not yet done so, according to law professor Jorge Morais Carvalho.

Water, waste and infrastructure

Castro Marim secures full EU funding for water works to Cortelha

Castro Marim council has signed a deal with the Fundo Ambiental to cover 40% of the cost of a water supply project serving Cortelha, Marroquil, Amendoeira, Beliche and Corte Gago. Combined with 60% already approved under Portugal 2030, the works, already underway for months, will now be fully funded by European money. A reservoir is also being built at Pero Vaz, with a planned link to the central supply subsystem via Vale do Gato still awaiting funding, in a component estimated at €2.5 million. The project follows earlier water network extensions in Pisa Barro and Azinhal and Odeleite.

Barcelos puts new €35.4m wastewater plant out to tender

The municipality of Barcelos has opened a public tender worth €35.4 million for a new wastewater treatment plant, with bids due by 23 October and 910 days allowed for construction. The facility will replace the current plant, built in 1999 and now considered obsolete, unable to cope with the town's demographic, urban and industrial growth, particularly textile industry effluent. The new ETAR will use advanced biological treatment plus filtration and ozone to remove dyes and pollutants, and will generate its own solar and hydroelectric power. Over 73,000 people are expected to benefit, with treated water returned to the Cávado river inside a protected natural park.

Ponte de Lima opens tender for €4.6m wastewater plant

The Ponte de Lima municipal council has launched a public tender for the design and construction of the Poiares wastewater treatment plant (ETAR), with a base price of €4.6 million. Published in the official gazette (Diário da República), the notice allows around 720 days to complete the contract in the Poiares parish, Viana do Castelo district. The work covers the project design and construction of the plant along with the infrastructure and interfaces needed for it to operate, including installation, testing and commissioning. Bids must be submitted by the 30th at 23:59.

BioSmart wins €1.5m contract to clean Alentejo sewage lagoons

BioSmart, part of the NOV Ambiente group, won a public tender from Águas Públicas do Alentejo worth €1.5 million to remove sludge from wastewater treatment lagoons. The three-year contract covers 35 treatment plants across 13 Alentejo municipalities, including Beja, Odemira and Santiago do Cacém. Sludge will be extracted using a pumping raft in nine lagoons and excavators in the remaining 26, then dried before being tested and sent for agricultural recovery or composting. The company's CEO described the award as recognition of BioSmart's technical capacity for large-scale environmental operations.

Portugal opens €30m call for wastewater reuse projects

The Sustentável 2030 programme has launched a €30 million funding call to adapt wastewater treatment plants (ETAR) for producing and distributing reclaimed water for non-potable uses. The PACS-2026-23 notice aims to boost circularity of water resources and strengthen responses to water scarcity. Municipalities, their associations, state and local business-sector entities, and municipal or intermunicipal concessionaires can apply via the Balcão dos Fundos. Applications run continuously in two phases, from now until September 2027, with co-financing of up to 85% across mainland Portugal's NUTS II regions.

Monção bans basements and bedrooms below flood level in new building rules

Monção's municipal master plan (PDM) now incorporates flood-risk management rules from the national PGRI for the Minho-Lima river basin, published in the Diário da República. In areas identified as flood-prone, new buildings can no longer have basements or bedrooms below the defined flood level, and in very high or high-risk zones, housing below that level is banned outright. Buildings must resist flood damage and use materials able to withstand prolonged water contact. After flood disasters, reconstruction is restricted, with preference given to relocating destroyed buildings outside risk zones and renaturalising artificial waterways.

Aveiro launches €36.2m tender for waste collection and street cleaning

Aveiro's municipal council has unanimously approved an international public tender for waste collection, transport and urban cleaning services, worth a base €36.2 million, more than three times the previous contract's €11.2 million. The eight-year deal, which also covers management of the municipal Ecocentre, demands higher quality standards and stricter monitoring, including unannounced inspections and financial penalties for non-compliance. It foresees more frequent collection in some areas, reinforced street sweeping and expanded cleaning at São Jacinto beach. The current contract, due to expire on 30 September, has been extended by six months to allow the new process to conclude.

Ponte de Lima buys five new waste collection vehicles

The municipality of Ponte de Lima has expanded its waste collection and street cleaning fleet, buying two heavy vehicles and three electric vehicles for €464,128.11 plus VAT. The council says the new vehicles meet EU safety and noise emission standards and will boost the response capacity of environmental and urban hygiene services across the municipality. It expects the renewed fleet to improve collection efficiency, cut problems linked to older equipment, and strengthen safety conditions for municipal workers. The electric vehicles are also presented as a step towards a more sustainable, lower-impact municipal fleet.

Infraestruturas de Portugal launches €750,000 solar and EV charging tender

Infraestruturas de Portugal (IP) has opened a €750,000 public tender to install solar panels and electric vehicle chargers at its Campus do Pragal in Almada. The plan includes two photovoltaic units with a combined 680 kWn capacity, on the roof of Building 2 and in the car park, plus 20 EV charging points. The system will be linked to IP's technical management platform for remote monitoring of production, consumption and charging. The works, framed as a strategic green public procurement initiative, are expected to take around 850 days to complete.

Plenergy opens two more fuel stations, reaches 22 in Portugal

Fuel retailer Plenergy has opened new service stations in Paredes and Loures, completing four openings across four districts in a single month alongside Castelo Branco and Ponte de Lima. The network now totals 22 locations in Portugal. The stations operate under Plenergy's hybrid model, offering fully automatic 24-hour refuelling plus daytime staff support, with prices around 10% below the regional market. The company aims to reach 30 active stations in Portugal by the end of 2026, with new projects already under way in Palmela, Coimbra, Vale de Cambra and Almada.

Portugal opens €4m call for farming and forestry information actions

Portugal's Ministry of Agriculture and the Sea has launched the first call under the PEPAC's Training and Information intervention, worth €4 million, to fund Information Actions in the farming, forestry and agri-food sectors. Farmers' organisations linked to IFAP's Single Application protocol can receive up to €300,000 per application, while other eligible bodies, including cooperatives, associations and technology centres, are capped at €70,000. Support covers 95% of costs for activities such as in-person sessions, publications, trade fair participation, videos and webinars, focused on water management, natural resource protection, financial literacy and digital transition. Applications are submitted via the Balcão dos Fundos da Agricultura.

Ponte de Lima agri-food tech centre gets green light to build

Portugal's government has authorised the Polytechnic University of Viana do Castelo to grant the Ponte de Lima municipality surface rights over land at its Agrarian School campus, clearing the way for the 3AR Technology Transfer and Valorisation Centre for the agri-food sector. The project costs around €4.5 million, with EU co-financing of roughly €2.9 million under the Norte 2030 programme. Construction, to be carried out by the municipality, should start in 2026 and finish within two years. The centre will focus on food, endogenous resources and sustainability, and aims to create close to 40 qualified jobs by 2030.

Alentejo 2030 funds training for ex-Sines power plant workers

The Alentejo 2030 programme has opened applications for individual training and certification support aimed at former workers of the Sines Thermoelectric Power Plant, who lost their jobs when it closed. The scheme, under notice ALT2030-2026-54, aims to boost their employability through courses that can lead to qualifications up to master's level. Priority areas align with the region's growth sectors, including renewable energy, agrifood, tourism, construction and the maritime economy. Only former plant employees affected by the closure are eligible. Applications remain open on a rolling basis until 26 February 2027 via the Balcão dos Fundos platform.

Housing cooperative urges launch of ready Banco de Fomento credit lines

At a parliamentary hearing requested by Chega, Virgílio Rocha, head of housing cooperative A Casa, said the Banco Português de Fomento has credit lines ready for housing cooperatives, offering 30-year maturities, but still awaiting Finance Ministry authorisation. His cooperative, building a 46-home cohousing project in Santo Isidro de Pegões, Montijo, cannot secure loans for older members because commercial banks cap terms at 20 years. Rocha also called for tax changes allowing capital-gains reinvestment exemptions when selling a home to join a cooperative, and clarification that shared facilities should qualify for the reduced 6% VAT rate on construction.

Dutch carbon procurement tool to launch in Portugal in October

The CO₂ Performance Ladder, a Dutch methodology that uses public procurement to push suppliers to cut carbon emissions, is being adapted for Portugal and will officially launch in Lisbon on 15 October. Aliados Consulting is coordinating the work with Dutch foundation SKAO, having analysed the national legal framework, trained public entities and run three editions of a preparatory programme. The next phase focuses on integrating the methodology into actual procurement procedures, aiming to make public purchasing decisions drive verifiable emissions reductions and push suppliers to track and report their climate performance.
