Wim de Haas · Circular solutions and governance researcher at Wageningen University & Research
Researchers from Wageningen University & Research (WUR) offer technical and administrative support to companies in the chemical, fashion, agricultural and food production sectors that want to work in a circular way. They help companies with questions specific to their branch, like a home furnishing centre that wants to reuse packaging waste but is finding that hard to do. Scientists from WUR take a look at how companies and municipalities can concretely address these types of issues. We are still at the dawn of a circular economy, so research and solutions are desperately needed. Which issues do you feel require a circular solution? ‘The circular economy is quite difficult to understand, but it boils down to closing the cycles in the most sustainable way possible,’ explains researcher Wim de Haas. ‘A simple example is that you throw potato peels onto the compost heap in the garden and then use the compost for your vegetable garden. Here, waste is used as a raw material.’ Researchers from Wageningen are working towards circular solutions in different fields. For example, valuable nutrients can be extracted from manure and the chemical industry can extract raw materials from agricultural waste streams and kitchen and garden waste, and no longer relies exclusively on petroleum. Even the fashion industry is also working more conscientiously on recycling. Another great example of circular solutions is the circular agrofood system.
Increasing urgency‘Many resources are finite and will become scarcer and more expensive or are only found in countries on which you don’t want to be dependent. Producing new raw materials from waste streams is, therefore, a good idea for both financial and geopolitical reasons,’ explains De Haas. A circular economy is also beneficial for the preservation of biodiversity and nature, because less harmful waste ends up in the environment while reducing greenhouse gas emissions will help mitigate climate change. ‘It is therefore becoming increasingly urgent to design the economy in a circular way. Despite this urgency, the circular economy in the Netherlands is still in its early stages. Last year, companies, civil society organisations and governmental authorities drew up agendas for the ‘Grondstoffenakkoord’ (national agreement on raw materials) for a circular economy in the Netherlands by 2050′. ‘However, the government doesn’t set any clear targets in this agreement. The objectives of the energy transition are very clear, while those of the circular transition have yet to be explicitly formulated,’ says De Haas.
“You now see that companies are renting or leasing products to clients or consumers or charge a deposit for them more frequently. An example of this a is bed manufacturer, who makes the mattresses in such a way that the materials can be reused.”Some large companies are developing circular technology, redesigning production processes and devising new business models. Discarded goods and electrical appliances are usually recycled, with a lot of raw materials being lost in the process. ‘It would be better if old washing machines and computers were returned to the manufacturer, who can recycle parts for new washing machines and computers,’ explains De Haas. ‘You now see that companies are renting or leasing products to clients or consumers or charge a deposit for them more frequently. An example of this is bed manufacturer Auping, who makes the mattresses in such a way that the materials can be reused. Companies like these are taking the initiative and have been awarded with prizes for their contribution to a circular economy as a result. However, there aren’t many good examples of circular practices yet,’ says the researcher.
Garden furniture made from old plasticAt what level can the cycle best be closed? At the level of a company, district, municipality, region, province, country, Europe, the world? That depends on the particular situation. Circularity within companies is obvious, but regions are just as capable of being circular. However, this type of cooperation is more difficult to organise, and that is exactly what De Haas is working on. He is currently involved in a project in the Arnhem-Nijmegen region with three business parks that want to use packaging waste to good effect by processing plastic into garden furniture. ‘But you immediately run into practical problems,’ says De Haas. If canteens, restaurants and festivals all bought the same type of plastic, the processing would become much easier.’
“A change in thinking and behaviour is needed both within companies and among consumers. The government has a big responsibility in providing information and education about the circular economy.”
