There is very little value to the ownership of the vast majority of chemicals unless they are used for their intended purpose. And yet, because of the traditional sell/own business model, the waste that results from over-purchasing is significant and systemic.  Further, the system is constantly driving toward selling more chemicals to make more profit, driving toward designed obsolescence and short-term use.  The chemical leasing model is one where the “sellers” supply the service or function rather than selling a chemical.  In this model, instead of selling as much chemical as possible (resulting in excess and waste), the motivation is to use as little of a chemical to accomplish the desired service as the same profit can be generated from delivering much less product.  Chemical leasing is a business model whose effectiveness has been demonstrated at large scale and has extensive potential to be expanded.
