Chemistry in nature is clean and efficient, whilst industrial chemistry is anything but.\u0026nbsp;\u003C\/p\u003E\u003Cp\u003E\u2018Chemical reactions in nature are incredibly efficient, generating very little waste and consuming very little energy,\u2019 said de la Escosura.\u003C\/p\u003E\u003Cp\u003EHe wondered whether, by mimicking biology more closely in industrial reactions, we could create a cleaner, more environment-friendly chemical industry.\u003C\/p\u003E\u003Cp\u003EThanks to funding from the EU, de la Escosura was able to join forces with researchers from countries such as Austria, the Netherlands and Switzerland to put these ideas to the test in a research initiative called\u0026nbsp;\u003Ca href=\u0022https:\/\/cordis.europa.eu\/project\/id\/862081\u0022\u003ECLASSY\u003C\/a\u003E that ended earlier this year.\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003ENatural advantage\u003C\/strong\u003E\u003C\/p\u003E\u003Cp\u003ELiving organisms function using biochemical reactions.

These processes are all very clean and energy efficient.\u003C\/p\u003E\u003Cp\u003EOn the other hand, today\u2019s industrial chemical industry that is used to power sectors such as health, energy, transport and housing creates vast amounts of waste.

Fluids, and the molecules within them, are sorted and guided through a series of chips or microreactors. Different molecules can be sent to different reaction chambers, and their progress through the device is closely controlled in a step-by-step progressive process.\u0026nbsp;\u003C\/p\u003E\u003Cp\u003EThe processing of synthetic chemicals requires several different steps. When you carry out these processes in a closed system, like a flask or industrial reaction chamber, at some point you need to stop, empty the reactor and then start the reaction again, explained de la Escosura.\u003C\/p\u003E\u003Cp\u003EMicrofluidics enables chemical reactions to occur in a more natural fashion. The reactors contain a mix of enzymes and other molecules that produce a chemical reaction. When one chemical reaction finishes, the compounds flow through the system to the next chamber and the next reaction. The benefit of this is that the overall process can run continuously.\u003C\/p\u003E\u003Cp\u003EThe CLASSY researchers have made good progress with these reactors, successfully creating a microfluidic device that breaks down vegetable fats to produce a biofuel to prove their concept.\u0026nbsp;\u003C\/p\u003E\u003Cp\u003EDe la Escosura acknowledges that the efficiency of the process could be further improved, but the hope is that, in the future, such devices could complete different tasks depending on what is fed into the system. More basic research is needed, he said, but the hope is that this approach could dramatically reduce waste and energy consumption, while improving chemical yields.\u003C\/p\u003E\u003Cp\u003E\u2018The goal is to minimise the impact that the chemical industry has on climate change and other environmental issues,\u2019 he said.\u003C\/p\u003E\u003Cp\u003EThis is particularly important as global chemical production is expected to\u0026nbsp;\u003Ca href=\u0022https:\/\/environment.ec.europa.eu\/strategy\/chemicals-strategy_en\u0022\u003Edouble by 2030\u003C\/a\u003E, according to the EU, which published its own \u003Ca href=\u0022https:\/\/environment.ec.europa.eu\/strategy\/chemicals-strategy_en\u0022\u003Echemicals strategy\u003C\/a\u003E in 2020 aimed at reducing the environmental and health impact of the chemicals sector as part of the EU\u2019s zero pollution goals and the\u0026nbsp;\u003Ca href=\u0022https:\/\/commission.europa.eu\/strategy-and-policy\/priorities-2019-2024\/european-green-deal_en\u0022\u003EEuropean Green Deal\u003C\/a\u003E.\u0026nbsp;\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003EBody chemistry\u003C\/strong\u003E\u003C\/p\u003E\u003Cp\u003EOn a similar path of investigation, researchers from Spain, Denmark, the Netherlands and Switzerland are exploring how complex chemical reaction networks (CRNs) created using microfluidic chips could be used for energy-efficient computing.\u0026nbsp;\u003C\/p\u003E\u003Cp\u003EThis is part of a 4-year research initiative called\u0026nbsp;\u003Ca href=\u0022https:\/\/cordis.europa.eu\/project\/id\/101046294\u0022\u003ECORENET\u003C\/a\u003E, also coordinated by de la Escosura, that received funding from the EU to design \u201cchemical computers\u201d that can solve real-world computing tasks and may ultimately be able to interact with the human body, although that is still some way off and beyond the current scope of CORENET.\u003C\/p\u003E\u003Cp\u003EThis isn\u2019t as outlandish as it might sound. \u2018The most efficient computer in the world is chemical \u2013 the human brain,\u2019 said de la Escosura.
