IChemE Global Awards 2025 – Shortlist

Clees • October 9, 2025

Aerbio and Otto Simon have been jointly shortlisted as finalists for the IChemE Global Awards 2025 in the Biopharma category.

Our entry, Clean Protein: Engineered for a Resource-Constrained World, showcases the research and engineering efforts being the development of Proton™, a protein-rich single-cell biomass produced using a novel aerobic gas-fermentation process, utilising hydrogen, oxygen, and carbon dioxide as feed gases.

This project has demonstrated the feasibility of producing a sustainable, high-quality protein ingredient at pilot scale, with applications in aquaculture and animal nutrition today, and the potential to expand to food-grade applications in the future.

The technical challenges of this work have been considerable. Designing and operating a continuous fermentation system with hydrogen and oxygen in flammable ranges required rigorous safety engineering: hazard studies, CFD modelling, ATEX compliance, and functional safety analysis were all critical. With no commercial-scale precedents to draw upon, designs were developed from first principles and validated through lab-scale experimentation and pilot-plant data. Despite the added complexity of international collaboration during the COVID-19 pandemic, the project successfully delivered a first-of-a-kind pilot facility, generating essential data to enable scale-up to demonstration and commercial scale.

The outcome speak for itself: Proton™ contains over 70% protein with a complete amino acid profile, delivers strong results in digestibility and extrusion trials, and has already shown positive performance in aquaculture and poultry feed applications. It can be produced with a fraction of the greenhouse gas emissions and water use of conventional proteins, while requiring no arable land and supporting biodiversity by reducing reliance on fishmeal and soy.

This nomination recognises the strength of our cross-disciplinary partnership, combining microbial fermentation expertise with advanced process design, safety engineering, and scale-up know-how.


Together, we are laying the foundations for a scalable, climate-positive protein platform that can contribute to global food security while reducing environmental impact.

We look forward to the awards ceremony later this year and to continuing our journey towards commercial deployment of this disruptive technology.

Engineering for Efficiency: Turning Energy Pressure into Opportunity UK industry continues to operate against significant economic headwinds, with high energy prices, increasing operating costs, strict regulatory requirements, geopolitical uncertainty and growing competition from emerging markets all placing pressure on margins. Within this context, energy consumption has become a critical factor in determining profitability and, in some cases, the ongoing viability of manufacturing operations. The Hidden Opportunity in Legacy Plant Much of the UK’s manufacturing base relies on established or legacy plant, designed and built when energy costs were lower and the commercial case for efficiency improvements was less compelling. As energy costs have risen, that calculation has changed. Well-targeted energy efficiency projects can now deliver meaningful long-term savings, improve operational resilience and strengthen business performance. Faster Payback. Stronger Margins. For many manufacturers, improving energy efficiency is now one of the most practical ways to protect and enhance operating margins. Projects that may once have been difficult to justify can now achieve significantly shorter payback periods, particularly where opportunities exist for heat recovery, improved process control, reduced steam and utility demand, optimised equipment operation, or targeted upgrades to existing assets. Engineering That Delivers Measurable Savings Otto Simon Ltd has a strong track record in integrating beneficial technologies into established industrial processes, helping clients improve efficiency and reduce operating costs. Our multidisciplinary engineering team works closely with clients to understand their processes, constraints and commercial objectives, identifying where engineering effort can be most effectively applied to deliver measurable energy and cost savings. From Opportunity to Operational Benefit Whether designing a complex heat integration network for a new build facility, assessing utility demand across an existing site, or delivering simple, cost-effective improvements to operational assets, OSL supports clients from initial opportunity identification through to project execution. Our focus is on pragmatic engineering solutions that can be implemented safely, efficiently and with a clear understanding of return on investment. Start with a Focused Energy Review Based on the conversations we continue to have with clients across process and manufacturing sectors, there is significant opportunity to reduce energy consumption, improve asset performance and deliver immediate and long-term operational benefits. In many cases, the first step is a focused review of current plant performance to identify realistic, prioritised opportunities for improvement. Ready to Find Your Energy Savings?  If you would like to understand where energy savings may be available within your facility, or discuss how targeted engineering improvements could support your business, please contact us at eng@ottosimon.co.uk to discuss the opportunity for us to undertake an energy survey of your plant.

The Employee Council hosted a successful potluck lunch with the team at United House, and it is fair to say the whole event was very well constructed. All staff members contributed to a diverse and extensive buffet of food, leaving us all slightly slower-moving, and a little tired afterwards. Dishes on offer included jerk pulled pork, chilli con carne, homemade focaccia, flapjacks and an array of meats, cheeses and fruit, all washed down with (non-alcoholic) beer and G&T. The spread had clearly been designed with generous safety factors in mind, and by the end we were all operating somewhere outside our normal design capacity. It’s important as an Employee Owned Trust to build strong working and personal relationships with our colleagues, and nothing helps strengthen these bonds quite like breaking focaccia with the rest of the team. Based on this strong turn out, we are keen to repeat the process next quarter, albeit hopefully with the catering slightly better calibrated to the team’s calorific requirements and without such significant overage. That said, having a little redundancy in the system is rarely a bad thing, particularly when the redundant item happens to be flapjacks. A huge thank you all those that made and bought food, and especially to Anna, our EOT President and Office Manager, for all the hard work, organisation and no doubt a fair amount of stress involved in arranging the event and chasing up various people to ensure we didn’t all bring crisps with no dips. Her project management kept everything on programme, avoided any major snack-based clashes, and ensured the final delivery was both structurally sound and thoroughly enjoyed.
