The major advantage of the chemicals introduced via the MBA is that they can deliver virgin-equivalent quality of both polyols and diisocyanates fraction. This makes them able to go up to 100% in foam formulations, making them suitable for sectors with high specifications.Production & Transformation of Flexible PU FoamA cradle-to-gate analysis of flexible PU foam (also called eco-profiles) shows that the impact of foam production on the life cycle of the product is minimal. This is not surprising because the foam industry is not a major energy consumer, as chemical reactions taking place in foam factories are exothermic.This does not mean that action cannot be undertaken to improve the life cycle of foam also in the production and transformation stage. Such an improvement can be supported by the usage of renewable energy, minimization of water usage and minimization of waste, notably via reduction or re-use of production cut-offs. Reduction of production cut-offs is made possible with latest digital technologies allowing to forecast which parts will be cut out of foam blocks even before the said blocks are produced. Re-use of production cut-offs in our industry has been practised for decades, considering that such cut-offs are used as such (flakes in cushions) or agglomerated into rebonded foam used in carpet underlay, gym mats etc. Today in wider Europe, more than 90% of post-industrial flexible PU foam (production cut-offs) is used to produce new products. Logistics: Finding New Ways to Improve Due to its cellular structure, flexible polyurethane foam is a lightweight material made mostly out of air. This explains why historically transporting foam over long distances was uneconomical and required to run trucks to transport relatively little foam. In the past decade, industry has developed technology and foam formulations allowing compression and rolling for storage and transportation. The famous bed-in-a-box mattress is probably the best example of that. This allows a much higher utilisation of transport and storage means.Other ways of minimising the environmental impact of logistics operations are by utilising multi-modal transport, by using alternative fuels (e.g. biodiesel, LBG) or by transitioning to electric-powered vehicles.
