Extension of LCA offers the most consistent solution. Developments in LCA are moving toward greater spatial detail and temporal resolution and the inclusion of social issues.

Creating a supertool with too many data and resource requirements is, however, a risk. Moreover, a number of social issues are not easily modeled in relation to a functional unit. The development of a toolbox offers the most flexibility regarding spatial and temporal information and regarding the inclusion of other types of impacts.
The rigid structure of LCA no longer sets limits; every aspect can be dealt with according to the logic of the relevant tool. The results lack consistency, however, preventing further formal integration. The third strategy, hybrid analysis, takes up an intermediate position between the other two.

This strategy is more flexible than extension of LCA and more consistent than a toolbox. Hybrid analysis thus has the potential to combine the strong points of the other two strategies. We present a number of examples of hybrid analysis to illustrate the potentials of this strategy.

Developments in the field of a toolbox or of hybrid analysis may become fully consistent with LCA, and then in fact become part of the first solution, extension of LCA. Volume 8 , Issue 3.

Then read how our TNO scientists could help you. We believe it is essential that companies assess the sustainability in their business processes with hard facts, if possible quantitatively. Therefore they need reliable and scientifically sound data based on sound LCA methodologies. TNO is an independent research laboratory. Since we have been developing LCA methodologies based on the latest scientific insights and translate these in practically applicable methods and tools to make sustainability tangible and measurable and hence improve your strategic business decisions.
TNO has executed a lot of studies and research, see examples below:. TNO has conducted a study to disposable shopping bags, see figure 1. In contradiction to the overall consumer perception, we found that wood based paper bags have a significant higher environmental impact than recycled plastic bags.
This study also provides clear guidance to more sustainable solutions. For more information read: Fewer bags, sustainable re use and good practice.
TNO can support you to identify your sustainability benefits during the development of new bio-based chemicals, coatings and polymers. Figure 2 shows an example for different ethanol products. Ethanol from fossil-based ethylene has a lower carbon footprint than ethanol from sugar cane. However, ethanol from sugar beet appears to be the most sustainable product.
In contradiction to our intuition, this analysis shows that bio-based chemicals are not always more sustainable than their fossil based alternatives. A number of companies have a sustainability assessment method in place. TNO has recently benchmarked the effectiveness of 21 existing methods. This evaluation framework is a basis for a reference methodology which is suitable for all business processes within manufacturing companies. Figure 3 shows that all existing methods have drawbacks in measuring the sustainability, particularly for operations.
Based on this benchmark study TNO helps companies to implement the most powerful sustainability assessment method in their organization. By means of sector life-cycle-analysis,TNO provides insights for industry partners and governments about the effect of measures to reduce their carbon footprint. In the report CO2 roadmap we have underpinned that the chemical sector has opportunities to reduce their carbon footprint with a factor 3. Materials can have a quite different environmental and health impact when processed and used on a nano-scale. In the project the use silver nano-particles in microfiber in cloths has been evaluated, see figure 5.
This expertise can be used during the development of coatings, conductive inks, or polymers in which metallic, carbon-nano-tubes, graphene or ceramic nano-particles play a vital role.

Before we offer our services we listen to your request and make a joint assessment. Based on that we mostly offer an tailored approach to meet your needs.
