Chemicals from cashew nut shell

Who knew you can use liquid extracted from cashew nut shell and use it for chemical feedstock?

The blog was immediately intrigued about CNSL given the unfamiliarity of this material. After a bit of googling, the blog came across this document submitted to the US EPA (dated June 2002) from New Jersey, US-based Cardolite Corporation about CNSL. Cardolite is another company working on CNSL for decades.
