To provide insight into the potential environmental impact of innovations in construction and infrastructure at an early stage of technology development, in particular those that contribute to the reduction of CO2 emissions. TNO is committed to this with next generation impact assessment.
The circular economy is still insufficiently anchored in existing analyses, such as the life cycle analysis (LCA), that aim to assess environmental impact. The impact assessment criteria are under development and should be made applicable to the four R's: reduce, recycle, reuse and remanufacture. By realising this, TNO makes it possible to calculate variables such as CO2 emissions and the environmental cost indicator (ECI) value and to provide insight into the consequences of choices for the future.
With next generation impact assessment TNO is focusing on the future. For example, how can we predict the environmental impact of technologies and innovations, which are also in a state of flux, by 2030 or 2050? If the industry is working on sustainable concrete, it is necessary to calculate the effect of recycling and the recycling methods that exist in the changing world.
TNO combines in-depth knowledge about life cycle analyses with domain-specific knowledge about, for example, construction, sustainability and the ecosystem. The analyses take into account every aspect of the circular economy.
The Netherlands aims to maximise the contribution of the built environment to the environmental and climate objectives. The optimum performance of a building lies in an integrated approach to its energy, climate and environmental performance over its entire lifespan. That is why TNO is working on innovations for both new buildings and renovations that will help to optimise the energy measures.
A circular economy is about stimulating reuse. For the built environment this presents a huge challenge. This means that the service life may be 80 years or even longer. Differentiation between upcycling and downcycling is also a challenge. Asphalt can be recycled in the top layer at high quality, but it can also be used as rubble in the foundation at low quality.
With solutions that quantify the environmental impact of the circular economy, TNO helps public authorities and large companies to make informed decisions.
Investments in construction are made for the long term. In a life cycle analysis it is therefore necessary to be able to calculate the environmental impact using future scenarios. This means that, for example, the energy transition in the models will result in both an increased use of renewable energy in 2030 and 2050 and an increase in sustainable transport.
Also growth in the use of secondary raw materials through recycling cannot automatically be included in the life cycle analysis. TNO researches the effects of new technologies, so that investments are based on developments that the construction industry is experiencing.
