The Spanish vehicle manufacturer, SEAT, has installed air-cleaning pavement in its Martorell plant in Barcelona.

The Spanish vehicle manufacturer, SEAT, has installed air-cleaning pavement in its Martorell plant in Barcelona.

The photocatalytic material is created by combining titanium dioxide and cement, which allows pollutant nitrous oxide (NOx) to be converted into water-soluble nitrates.

The conversion happens when the self-cleaning and pollutant-trapping slabs are exposed to light, oxygen, and NOx at the same time.

The pavement slabs span across 4,000sqm of the facility, which is anticipated to lover NOx pollution on the site by 40%.


By the end of the year, SEAT plan to install an additional 26,000sqm of the pavement across walkways of its Martorell plant.

With the total 30,000sqm covered in the air-cleaning material, the firm expects to annually save 5.2 tonnes of NOx emissions.

SEAT is examining is the material can be used on 147,000sqm of the site’s exterior walls, in the form of paint.

The manufacturer surpassed it sustainability goal of reducing its environmental impact by a quarter by 2020, against a 2011 baseline.

Two years before anticipated, the firm has reduced its environmental impact by 35.5%.

Drax advances biomass strategy with Pinnacle acquisition

Drax is advancing biomass following Pinnacle acquisition it reported in a trading update

Drax' recently completed acquisition of Pinnacle more than doubles its sustainable biomass production capacity and significantly reduces its cost of production, it reported in a trading update.

The Group’s enlarged supply chain will have access to 4.9 million tonnes of operational capacity from 2022. Of this total, 2.9 million tonnes are available for Drax’s self-supply requirements in 2022, which will rise to 3.4 million tonnes in 2027.

The £424 million acquisition of the Canadian biomass pellet producer supports Drax' ambition to be carbon negative by 2030, using bioenergy with carbon capture and storage (BECCS) and will make a "significant contribution" in the UK cutting emissions by 78% by 2035 (click here).

Drax CEO Will Gardiner said its Q1 performance had been "robust", supported by the sale of Drax Generation Enterprise, which holds four CCGT power stations, to VPI Generation.

This summer Drax will undertake maintenance on its CfD(2) biomass unit, including a high-pressure turbine upgrade to reduce maintenance costs and improve thermal efficiency, contributing to lower generation costs for Drax Power Station.

In March, Drax secured Capacity Market agreements for its hydro and pumped storage assets worth around £10 million for delivery October 2024-September 2025.

The limitations on BECCS are not technology but supply, with every gigatonne of CO2 stored per year requiring approximately 30-40 million hectares of BECCS feedstock, according to the Global CCS Institute. Nonetheless, BECCS should be seen as an essential complement to the required, wide-scale deployment of CCS to meet climate change targets, it concludes.
