Who gets a say in Portugal’s clean-energy map?

Questions about where infrastructure belongs shaped Portugal’s sustainability news this week. A smaller renewable energy map followed strong public opposition, while Alenquer residents challenged a biomethane proposal and ZERO sought safeguards for data centres. Elsewhere, researchers and repairers tested practical responses, from preparing trout for release to filtering wastewater with brewing waste and keeping electrical goods in use.

What shaped the week

Portugal’s low-carbon infrastructure faces a basic planning question: what should go where, and under what conditions? The government reduced the proposed renewable energy Green Map from 7% to about 4% of national territory after 94% of nearly 8,500 consultation submissions opposed it. Protected areas were excluded, and designated locations fell from more than 1,300 to about 800. That revision does not settle the wider argument. In Alenquer, residents fear odours, lorry traffic and damage to water lines from a proposed €20.5 million biomethane plant. Construction has not been approved, and consultation remains open until 15 September. ZERO, meanwhile, says rules for data centre expansion lack binding safeguards for energy, water and heat reuse. Its figures show the scale of the concern, although they describe projected demand rather than an outcome. Wildlife work shows why careful siting and evidence matter. Teams now track 56 black vultures, and the data informs technical opinions on renewable projects near their habitats. In Campelo, trout are being raised with shelters, live prey and little human contact after genetic monitoring found earlier released farmed fish almost never survived to adulthood or reproduced. Quinas, a rehabilitated leatherback turtle, travelled 1,283 kilometres in 20 days after release, confirming normal migratory behaviour. Elsewhere, circular solutions stayed practical. Porto repairs avoided 660.726 kg of e-waste in six months, while University of Aveiro research turned spent brewer’s grain into reusable materials for filtering antibiotics from wastewater.

Stories behind the week

Energy needs public limits

Renewable zones were reduced after strong consultation opposition, while disputes over a biomethane plant and data centre expansion focused on local water, traffic, land and power. Together, the stories ask what credible safeguards and meaningful consultation require.

Portugal shrinks renewable energy 'Green Map' from 7% to 4%

The government has cut nearly in half the share of national territory earmarked for fast-tracked wind and solar projects, from 7% to about 4%, EMER president Manuel Nina told Expresso. Municipalities will only need to designate 1% of new land as acceleration zones (ZAER), with flexibility to swap sites and two years to update local master plans. The reduction follows a public consultation in which 94% of nearly 8,500 submissions opposed the plan, and reflects exclusion of protected areas identified with the ICNF and APA. The number of designated locations fell from over 1,300 to about 800.

Alenquer residents oppose planned biomethane plant in Marés

Residents of Alenquer criticised a planned biomethane plant during a council meeting, citing fears of bad odours, heavy truck traffic and harm to local water lines. The €20.5 million project by Gás da Terra would process 84,000 tonnes of agricultural effluent yearly in Marés, producing biomethane and biofertiliser. Mayor João Nicolau said the council has only approved a preliminary information request, not construction, and shares residents' concerns, insisting the company must guarantee no odour impact. The project is open for public consultation until 15 September, with environmental licensing decisions expected by mid-2027.

ZERO warns Portugal's data centre rules lack sustainability safeguards

Environmental group ZERO has criticised a government resolution (RCM 70/2026) that opens the way for data centre expansion in Portugal, saying it fails to guarantee these facilities support the climate transition. ZERO warns that meeting projected peak demand of 41GW via solar power alone would require covering about 3% of national territory in panels, consuming as much water as the whole Lisbon metropolitan area, and multiplying planned battery storage capacity 40-fold. Data centre grid connection requests already account for over 70% of power sought from REN. ZERO calls for binding rules on renewable energy additionality, water use, energy efficiency and heat reuse, warning of energy enclaves disconnected from local economies.

Recovery built on evidence

Black vultures, trout and a leatherback turtle each show conservation as patient, evidence-led work. Tracking movement, changing captive rearing methods and documenting rehabilitation all help teams judge whether animals can survive, reproduce and navigate the pressures around them.

56 black vulture chicks now tracked by GPS in Portugal

Portugal's LIFE Aegypius Return project has fitted 13 more black vulture chicks with GPS/GSM trackers this breeding season, bringing the total monitored since 2023 to 56. Field teams visited breeding colonies in Douro Internacional, Tejo Internacional, Herdade da Contenda and Vidigueira/Portel, also ringing chicks and collecting biological samples for research. The tracking data helps assess environmental threats and informs technical opinions on renewable energy projects near vulture habitats. The species, extinct as a breeder in Portugal for 40 years until 2010, remains classified as endangered, with wildfires, extreme weather and expanding wind and solar projects among the risks facing its recovery.

Portuguese hatchery raises trout to survive in the wild

At the Posto Aquícola de Campelo, in Figueiró dos Vinhos, fish are raised in tanks fitted with pebbles, roots and shelters, fed live prey and kept away from human contact, as part of a rewilding process. The approach follows years in which Portugal's nature conservation institute, ICNF, released farmed trout into rivers to restock them, only for genetic monitoring to show that almost none survived to adulthood or reproduced. Campelo's method aims to prepare fish to fend for themselves once released into the wild.

Rehabilitated leatherback turtle case published as scientific study

A study published in June in Chelonian Conservation and Biology details the 2019 rehabilitation of Quinas, an adult leatherback turtle weighing around 300 kilograms, found entangled in fishing gear off the Algarve coast. Treated for 48 days at Zoomarine's Porto d'Abrigo in Albufeira, the turtle was released with a satellite tracker and travelled 1,283 kilometres towards the Canary Islands in 20 days, confirming normal migratory behaviour. The knowledge gained is now being applied to rehabilitate Molly, a loggerhead turtle from Ireland currently at the same centre. Leatherbacks are listed as Vulnerable by the IUCN.

Waste becomes a resource

Repair networks in Porto kept appliances in use, while researchers and manufacturers found new roles for brewing waste and recycled plastic. These efforts tackle different parts of the material cycle, from product design and repair to wastewater treatment.

Porto repair project CREW prevents 660kg of e-waste in six months

The CREW project, run by LIPOR with ERP Portugal, closed its first half-year with 660.726 kg of electrical and electronic waste avoided through repair. Its network of centres assessed 258 devices for repair potential, successfully fixing 76 and saving 353.628 kg of waste. Alongside this, 12 Repair Café sessions involving 124 participants and 36 hours of collective work assessed a further 124 devices, repairing 66 and avoiding another 307.098 kg of waste. Small appliances were the most common items repaired in both settings.

Plasdan finds way to recycle plastic inside food packaging

A new EU regulation, in force since mid-month, requires packaging to incorporate recycled material, aiming to boost recycling and reuse of a scarce raw material that is a major production cost for industry. The rules have so far been less strict for food packaging that touches food directly, because suitable technology did not exist. According to the article, Portuguese company Plasdan has now developed a way to place recycled plastic inside the packaging's core layer, addressing this previously unresolved technical gap.

Aveiro researcher turns brewing waste into water filter

A University of Aveiro researcher, Érika Sousa, has developed biochar and activated carbon from spent brewer's grain, a major by-product of beer production, to remove antibiotics such as sulfamethoxazole, trimethoprim and ciprofloxacin from wastewater. Using chemical activation and microwave pyrolysis, described as more energy-efficient than conventional methods, the materials performed competitively against commercial activated carbon. Surface modifications and molecularly imprinted polymers improved selectivity when multiple contaminants were present, and thermal regeneration allowed the material to be reused. The work, part of a doctoral thesis at CESAM, is presented as a circular economy approach to more sustainable wastewater treatment.

The map keeps filling in. This week we added 5 projects and 52 events. Sustainable Living now connects 367 projects, 202 upcoming events and 745 people across Portugal.
