  The idea seems futuristic: At ETH Zurich, various disciplines are working together to combine conventional materials with bacteria, algae and fungi. The common goal: to create living materials that acquire useful properties thanks to the metabolism of microorganisms – "such as the ability to bind CO₂ from the air by means of photosynthesis," says Mark Tibbitt, Professor of Macromolecular Engineering at ETH Zurich.

  An interdisciplinary research team led by Tibbitt has now turned this vision into reality: it has stably incorporated photosynthetic bacteria – known as cyanobacteria – into a printable gel and developed a material that is alive, grows and actively removes carbon from the air. The researchers recently presented their "photosynthetic living material" in a study in the journal Nature Communications.

Industry’s Path to a Greener Future: A Perspective on Current Sustainable Practices and Areas of Opportunity. ACS Sustainable Chemistry & Engineering, 13(19), 6849–6874. https://doi.org/10.1021/acssuschemeng.5c00741

  Abstract: Chemistry is directly and indirectly related to some of the most polluting industries, making it exceptionally critical for chemists to act and develop novel solutions toward more sustainable industrial practices. In this perspective, participants of the 2023 ACS Summer School on Green Chemistry & Sustainable Energy describe state-of-the-art developments that the chemical industry has spearheaded to reduce greenhouse gas (GHG) emissions and contribute toward achieving the 2030 Agenda for Sustainable Development. Herein, we illustrate a variety of methods that the chemical industry has employed, ranging from technological factors, such as using catalysis, implementing AI to reduce energy-intensive processes, and developing carbon capture technology and sustainable fuels, to socioeconomic factors─incorporating circularity, society targeted innovation and education, and developing successful collaborations between the private and public sectors. This perspective aims to trigger discussions and highlight how multifaceted approaches are necessary to support the transition to a greener industrial sector.

ACS Sustainable Chemistry & Engineering, 13(1), 5–29. https://doi.org/10.1021/acssuschemeng.4c07582 [open access]
  
  Abstract: Among the most active areas of chemistry research today is that of carbon dioxide utilization: an area of research that was viewed as futile and commercially impractical not so long ago due to the energetic stability of the CO₂ molecule. The breakthroughs that largely began in earnest in the 1990s have accelerated and now make up a diverse and plentiful portfolio of technological and scientific advances and commercialized technologies. Here, “The CO₂ Tree” is presented as a tool to illustrate the breadth of potential products from CO₂ utilization and to communicate the potential of these chemical breakthroughs to address the greatest challenge that society faces today: climate change. It is intended to be useful for scientists, engineers, legislators, advocates, industrial decision-makers, policy makers, and the general public to know what is already possible today and what may be in the near future.

  A study describes a new method of recycling silicone waste (caulk, sealants, gels, adhesives, cosmetics, etc.). It has the potential to significantly reduce the sector's environmental impacts. This is the first universal recycling process that brings any type of used silicone material back to an earlier state in its life cycle where each molecule has only one silicon atom. And there is no need for the raw materials currently used to design new silicones. Moreover, since it is chemical and not mechanical recycling, the reuse of the material can be carried out infinitely.

  For the first time, scientists have mapped microplastic distribution from the surface to the deep sea at a global scale – revealing not only where plastics accumulate, but how they infiltrate critical ocean systems. For the study, researchers synthesized depth-profile data from 1,885 stations collected between 2014 and 2024 to map microplastic distribution patterns by size and polymer type, while also evaluating potential transport mechanisms.              

  Results, published in Nature, reveal that microplastics are not just surface pollutants – they’re deeply embedded in the ocean’s structure. Ranging from a few to thousands of particles per cubic meter, their size determines how they move: smaller microplastics (1 to 100 micrometers) spread more evenly and penetrate deeper, while larger ones (100 to 5,000 micrometers) concentrate near the surface, especially within the top 100 meters of gyres. Gyres act like massive, slow-moving whirlpools that trap and concentrate floating debris – especially plastic.

  Microplastics and the much smaller nanoplastics enter the human body in various ways, for example through food or the air we breathe. A large proportion is excreted, but a certain amount remains in organs, blood and other body fluids. In the FFG bridge project Nano-VISION, which was launched two years ago together with the start-up BRAVE Analytics, a team led by Harald Fitzek from the Institute of Electron Microscopy and Nanoanalysis at Graz University of Technology (TU Graz) and an ophthalmologist from Graz addressed the question of whether nanoplastics also play a role in ophthalmology. The project partners have now been able to develop a method for detecting and quantifying nanoplastics in transparent body fluids and determining their chemical composition. As an exemplary application of the method, the research team is investigating whether intraocular lenses release nanoplastics. There have been no such studies to date, and initial results have already been submitted to a scientific journal. 

• We know nanoplastics are a threat -- this new tool can help us figure out just how bad they are

  While the threat that microplastics pose to human and ecological health has been richly documented and is well known, nanoplastics, which are smaller than one micrometer (1/50th the thickness of an average human hair), are far more reactive, far more mobile and vastly more capable of crossing biological membranes. Yet, because they are so tiny and so mobile, researchers don't yet have an accurate understanding of just how toxic these particles are. The first step to understanding the toxicology of nanoplastics is to build a reliable, efficient and flexible tool that can not only quantify their concentration in a given sample, but also analyze which specific plastics that sample contains.

  An international team of scientists led by the University of Massachusetts Amherst recently announced in Nature Water the development of a new tool, known as the OM-SERS setup, which can do all of these things and can furthermore be used to detect particular nanoplastic concentrations and polymer types in solid samples, such as soils, body tissues and plants.
