A new treatment process from thyssenkrupp Uhde converts phosphogypsum into a valuable feedstock for clinker production and can generate sulphuric acid.

Nextchem, part of MAIRE, has licensed its proprietary NX Circular™ high‑temperature gasification technology to SUSTAERO GP Inc. for a biomass‑to‑syngas unit feeding a new SAF plant in Canada.

Topsoe has entered into an agreement with Texas-based sustainable fuels and chemicals technology company BioVeritas to unlock advantaged feedstocks for existing infrastructure. The agreement will enable fuel producers to license Topsoe’s HydroFlex® technology alongside the Bio-Veritas Process™ to produce renewable fuels from second-generation feedstocks, such as woody biomass, corn stover, wheat straw, and similar waste and residual biomass. The BioVeritas Process™ converts second-generation feedstocks to advantaged intermediates, called KEY-Tones™ that can be processed by Topsoe’s HydroFlex® technology to unlock production of renewable fuels using second-generation feedstock.

HyOrc Corporation says that it has signed a project development and technology agreement with Bulgaria-based OnEnergy Group to develop a waste-to-methanol facility. Under the agreement, HyOrc will serve as the technology partner for Stage 3 of the project, which focuses on thermochemical conversion of refuse-derived fuel (RDF) into green methanol. The facility is designed to process approximately 50,000 t/a of RDF, operating around 330 days per year with a daily throughput of approximately 150-155 t/d. Expected methanol production capacity is approximately 38-42 t/d (13,200 t/a), subject to final engineering configuration.

We speak to Elise van der Linde, Fertipaq’s manager, about their latest product launch.

Tibaut Theys explains how circular solutions from Prayon Technologies are allowing widespread phosphogypsum reuse.

Nitricity has secured $50 million in funding and commenced building a liquid fertilizer production plant in Delhi, California.

NEXTCHEM (MAIRE), Mana and Equinor enter strategic partnership to explore the potential development of large-scale waste-to-methanol project

VK Arora of KPI examines the technical and operational challenges of decarbonising legacy and new ammonia plants, drawing on a European case study of full-scale conversion supported by robust process and integration design. It also presents three US case studies exploring partial strategies, such as green hydrogen blending and oxygen enrichment, to reduce CO2 emissions and improve throughput. Together, these examples highlight a phased, cost-effective approach to decarbonisation, with blue hydrogen serving as a near-term transitional feedstock.

The production of methanol from waste offers a groundbreaking solution for sustainable urban waste management as well as producing an alternative renewable fuel for maritime transport. Giacomo Rispoli, Andrea Angeletti and Alessia Borgogna of Nextchem provide an overview of the waste conversion process and its application.
