A thermochromic pigment composition including compounds of formula (I):

##STR00001##

in which: X represents CHR.sub.2, O, OCO or CHCH; Y represents O, COO, or OCOO; R.sub.1 represents H or (CH.sub.2).sub.pCH.sub.3; R.sub.2 represents phenyl or H; m=12-18; n=0-14; p=12-18; and on the condition that, if n=0, X represents CHR.sub.2 or CHCH.

The thermochromic pigment compositions having compounds of formula (I), include thermochromic pigment microcapsules. The thermochromic pigment capsules are useable for thermochromic pigment compositions in ink which may be used writing instruments.

This invention relates to the field of contaminated plastic waste decomposition. More specifically, the invention comprises methods and systems to decompose contaminated plastic waste and transform it into value-added products.

Tin (II) glucarate is found to be effective alone and in combination with other tin compounds for catalyzing the reaction of carboxylic acids such as furan-2,5-dicarboxylic acid, terephthalic acid and adipic acid with alcohols such as the C1-C3 alcohols.
