The solutions are unaddressed but workable. Schemes are being developed to handled demolition waste, but at this point, no demolition is being done. EPS is manufactured using pentane as the blowing agent. Although volatile, pentane is present in very small amounts. The polystyrene itself is a petroleum product, which is a significant issue.
Petroleum products are non-renewable, and although relatively plentiful now, finite as a resource.
A good argument could be made for the use of non-renewable resources only being used for durable use which is recyclable. SIPs would be a perfect example of this use. Energy used to manufacture SIPs is relatively insignificant. The glue used is non-polluting in use and disposal. The oriented strand board is an excellent use of transition from non-renewable resources to renewable resources.
