In the chemical and pharmaceutical sectors everything revolves around molecules. The raw materials, fuels and plastics produced by the sector are – often unseen – incorporated into all aspects of our daily lives. From the paint on the wall to the painkillers in the medicine cabinet, from the helmet of the cyclist to the solar panels on the roof. Consumers are often unaware of the crucial role that chemistry plays in the familiar objects they use day after day.

The sector strives for sustainable and circular products to create welfare and wellbeing within the planetary boundaries.

Molecules everywhere, chemistry everywhere

The chemical sector directly or indirectly contributes to almost all the material that our society carries, protects, nourishes and transports. This is also apparent from a report of the European Commission, which states that no less than 95 percent of all products and goods in Europe are related to chemicals or chemical processes.

Chemistry is therefore an industry that is strongly anchored in all parts of our society and connected to just about all other economic sectors. This means that chemistry is often at the start of very complex value chains. They can be local, but also European or even global.

Economy of the future

The chemical and life sciences sector is therefore an important lever to make the transition to a circular economy a success. This is a great opportunity, but it is also a great responsibility to help lay the foundations for the circular economy of the future.

We are in the aftermath of a linearly structured economy. We discard products and materials at the end of their useful life. It then becomes waste that we recycle in the best case, but still dump or incinerate far too often. In this way, many valuable substances and materials are lost.

A circular economy is organised differently. Waste becomes raw material and materials circulate in a closed cycle model in which they are re-used as long as possible and their social and economic value is maximised. Thanks to that circularity, fewer virgin raw materials are needed and that is a benefit for the environment.

Circulating is cooperating

For example, production waste from agriculture or the food industry can be used as a bio-based raw material in the chemical sector, while chemicals can be recovered even more and better from the waste flows of other sectors thanks to new technologies. In a circular economy, companies in different branches of industry therefore become even more dependent on each other than before, because the end product or residual product of one is the raw material for another.

This form of industrial symbiosis has long been the normal course of events in the chemical and life sciences industry where by-products and energy are exchanged between companies. The widely branched and fine-meshed pipeline network that connects the chemical cluster in Antwerp with the rest of Belgium and Europe is a good example of this.

Already in the nineteenth century, materials and energy cycles were included in the floor plan of chemical installations. Since the oil crises of the seventies and eighties of the last century, the use of residual heat and residual products has become an industrial reflex within the same chemical company but also between various neighbouring companies.

A circular economy goes even further. Where industrial symbiosis takes place between companies in often clearly defined industrial zones, the circular economy wants to encompass the entire economy and therefore also the many products that we all use every day. This has a very broad impact on purchasing procedures, logistics processes, financing models and recycling methods, among other things.

Circular is thinking ahead

Circular entrepreneurship starts with circular thinking. In the design phase of a product or a process, consideration must be given to how the product can be given a second life at the end of its life cycle, or how the process can be as efficient as possible. Therein lies the strength of chemistry because, like no other, it possesses knowledge about molecules and materials, about chemical and biotechnological processes of creation and transformation.

That knowledge is continuously deepened by increasing investments in research and development. Through the innovations that are now underway, the chemical industry is building the circular economy of tomorrow. For example, we are investing heavily in research into climate-neutral raw materials such as biomass, recycled plastics or even CO2.

Molecules of the future

For biodegradable materials and molecule the main use of this property of biodegradability is focused on when chemicals are destined to come into contact with the environment during their use. Such as for lubricating oil from chainsaws in forestry, water-soluble cosmetics or sutures after an operation.

When inventing new molecules, systematic screenings are done to select substances that pose no risk for workers and consumers, for animals and plants. Safety is rooted in the DNA of the chemical and life sciences sector and forms a permanent point of attention in every innovation process.

Risk is not the same as danger

The very fact that the benefits for society of a potentially dangerous substance are sometimes so important – such as with certain catalysts that yield huge returns in specific production processes, or which are necessary to produce hydrogen or to develop new medicines – makes further research worthwhile, even if a particular substance has intrinsically hazardous properties.

In the chemical and pharmaceutical industry, toxic or corrosive substances are often used that can be very hazardous. But that danger depends on how great the risk is that something or someone is exposed to it. Compare it with a cobra. If that life-threatening venomous snake suddenly crawls around your living room, that is a big risk. If the animal in the zoo is in a secure cage, that risk is practically zero. It is the same in the chemical and life sciences. Hazardous chemicals can be used safely as long as the risks are manageable and managed.

Safe and responsible business

The European legislation REACH (Registration, Evaluation, Authorisation and Restriction of Chemicals) is there to optimally protect people and the environment against the possible risks that chemical substances can pose. This not only concerns chemicals that are used in industrial production processes, but also substances that we use in our daily lives.

This European regulation obliges companies to thoroughly test health and safety risks of chemicals before they can be manufactured, placed on the market or used in production processes or products. The data from more than 22,000 substances are publicly available on the website of the European Chemicals Agency (ECHA). With almost 4,000 registered substances, Belgium is among the leaders in Europe.

In this way, REACH ensures that Europe sets the tone worldwide in terms of the safety and circularity of chemical substances. However, the system still does not function to best advantage. Frictions often arise at the interface between scientific insight, industrial innovation and political decision-making. This can sometimes lead to openly questioning decisions by recognised European agencies, after which individual member states each go their own way and the same rules do not apply everywhere in Europe hampering the single market.

This undermines a system for which we as a welfare region are rightly being envied. A stable legal policy framework that maps risks and manages them appropriately is therefore a permanent point of work. This is the only way the chemical sector can contribute actively through its molecules and materials to sustainable products that retain their value for a long time in a circular economy and that can be re-used after their first use, whether or not in the same application.

The challenges for the circular economy are major and diverse. Innovation is crucial for new forms of recycling, smart eco-design, and even leasing chemicals. New substances, techniques and processes must be developed for this: chemical, technical or biotechnological in nature.

Assessing the safety and sustainability of these novelties is no easy matter, moreover new technologies are developed. Luckily, current legislative frameworks are built to assess these risks from new products and uncertainties – although legislative integration and coordination could still be improved. Transparent procedures and clear decision-making are a must, as is social support for what constitutes an acceptable level of risk.

In addition, it is essential to be able to make the right choices in a scientifically based way. This complex assessment spreads across various policy areas. This requires reliable and comparable life cycle analyses, multidisciplinary collaboration and even the application of digitisation and artificial intelligence to be able to analyse faster more data more accurately.

Closing the circle

All this illustrates the need for the right talents and skills to work on circular and meaningful solutions within and outside the sector. Chemistry is at the start of many value chains and is therefore ideally placed to help close the circle of the circular economy. But we are not there yet with a handful of circular products. The circular economy is by definition a cooperation model that is still too often hampered by legal thresholds in existing (linear) rules.

Moreover, a circular economy only has a chance of success if it is competitive and profitable. It must therefore be supported by the financial sector and governments for more investments and smoother delivery of permits for circular projects whilst making no concessions on safety and environmental standards. The government must also guarantee stricter enforcement to ensure that imported goods meet the high European safety and quality requirements. In this way we prevent the circular economy within Europe from being disrupted by inferior material flows that hamper reused and recycling of material streams.

Lasting prosperity

The success factor of the chemical and life sciences lies in its extensive and varied range of products that guarantee well-being and quality of life. Integrating social added value into a circular model must become the basic motivation for all forms of entrepreneurship. Sustainable chemistry is one that fits within the planetary boundaries and can thus provide lasting prosperity.

Key challenges

  1. Seize the opportunities of the circular economy by developing new products and services together with our clients.
  2. Set up collaborative partnerships and encourage knowledge sharing to put the circular economy into practice, from product eco-design to waste management, in order to keep materials at their highest value.
  3. Apply life cycle thinking as a guiding principle in the sustainable selection of resources and materials.
  4. Ensure the safe and responsible use of chemicals and substances throughout the whole value chain by maintaining a strong product stewardship.
  5. Advocate and contribute to reduce the hurdles in current legislation embedded within a risk-based approach.
