Repsol has approved a historic €800 million investment in Ecoplanta, a pioneering project in Europe to transform urban waste into renewable fuels and circular products, adding a solution for reducing CO2 emissions in the transport sector, while at the same time promoting the circular economy. Located in Tarragona, the facility will be the first in Europe to produce methanol from municipal waste via a gasification process developed by Enerkem - a technology company in which Repsol is a partner – using waste that would otherwise end up in landfills or be incinerated.

Maire Group subsidiary MET Development, together with Eni and utility company Iren Ambiente, have started the permitting process for a renewable methanol and hydrogen plant at Eni’s refinery in Sannazzaro de’ Burgondi near Pavia. The plant will be developed using NextChem’s NX Circular™ technology, which allows the plant to convert waste by generating syngas, which is subsequently used to produce high quality sustainable fuels and chemicals. Once completed, the plant will be able to convert approximately 200,000 t/a of non-recyclable waste supplied by Iren’s waste management unit Iren Ambiente into synthesis gas. This will in turn be converted to produce up to 110,000 t/a of renewable methanol, as a potential fuel for decarbonisation of the maritime sector. It will also produce up to 1,500 t/a of hydrogen, which could be used in refinery processes, reducing CO2 emissions compared to fossil-generated hydrogen, or, alternatively, for sustainable mobility in road and rail transport. The plant will also recover 33,000 t/a of inert granulate, which can be used for the cement industry. The plant will use infrastructure and services already available at the refinery to optimise costs.

Carbon Recycling International (CRI), which operates a geothermally powered green methanol plant at Svartsengi, 40km southwest of Reykjavik, had to evacuate its site in late November when a 3km fissure opened in the earth a few kilometres away and lava began spilling across adjacent land. Satellite photos of the area taken on November 24 show a large field of molten and cooled lava to the north, west, and south of Svartsengi, though the plant itself remained undamaged. CRI’s Iceland facility runs on CO2 , water, and renewable electricity from the Svartsengi geothermal power station. CRI says the low-carbon energy source allows it to produce 4,000 t/a of methanol with a greenhouse gas footprint just 10–20% that of conventional methanol.

Van Iperen International is pursuing an ambitious sustainability strategy to cut its carbon footprint by 50%.

As more focus extends to a circular economy, there are industry wide discussions on whether future global sulphur demand will be challenged by the energy transition and decarbonisation. Hannes Storch, Collin Bartlett and Marcus Runkel of Metso discuss how the recycling of pyrite tailings could address some of these issues.

Join us at the CRU Sulphur + Sulphuric Acid 2024 Conference and Exhibition in Barcelona, 4-6 November, for a global gathering of the sulphur and sulphuric acid community. Meet leading market and technology experts and producers, network, share knowledge, and learn about market trends and the latest developments in operations, process technology and equipment.

The nitric acid industry has made great strides in reducing nitrous oxide emissions over the past few decades, but emissions from agriculture due to nitrogen fertilizers remain a problematic source of N2 O in the atmosphere.

Aparna Saiju and Nishevitha U G of SLB-MPS explore the concept of energy optimisation using power recovery turbine (PRT) technology in amine sweetening units, focusing on its potential benefits, implementation strategies, and environmental implications.

Levity Crop Science has a growing reputation as a leader in functional fertilizers, offering novel products that boost nitrogen and calcium efficiency and the crop uptake of micronutrients such as boron, molybdenum and silicon. This has culminated in the recent completion of a new research and development centre near Preston in the UK.

The newly-patented SWIFT process is designed to sequester fluorine at phosphoric acid plants in an environmentally responsible way. It can also offset the costs of fluorine management by generating a saleable dicalcium phosphate (DCP) end-product as an additional revenue stream. A number of capex and opex advantages provide the SWIFT process with highly favourable economics, as James Byrd of JESA Technologies explains.
