Surely by the time they solve the issue of plastics there will be different feedstocks such as PIR boards from buildings reaching their end life that will require disposal.
Another example of an alternative is with forestry and tree stump harvesting. They already harvest tree stumps for biomass applications but the advantage maybe of PHE's plant is that it may have a quicker turn-around time. One of the issues however maybe the water content of the timber, another is how can the outputs be harvested in rural locations?
Another variable is that although the first and probably all the current plans relate to a fixed site, the question is could this type of plant be designed and scaled so it can easily be transported between sites with quick set up times. Whilst this may be inefficient in urban areas, in rural communities this may provide an answer to a considerable reduction in feedstock miles to plant. Economically this may be advantageous for both recyclable and non recyclable plastic.
Whilst this is maybe wishful thinking on my part and pie in the sky, engineering wise is it doable? Would it be an efficient use of resources? That's for the engineers and accountants. I have no hesitation in top slicing projects for highest rewards and therefore maximising the margins, but at some stage this will probably have to come down the food chain in feedstock terms and I believe it is always best to widen the search for opportunities.
I'm sure many of you who read this board could provide many examples of opportunities that PHE should / could review for viability. If you have, I suggest you send them in to PHE.
Looking forward to the future.
