Then why not collect those parts to return them to the manufacturers.
I'm sure Thomas&Betts will be glad to get those back and find a way to re-use them and sell to you again.
Over here in the Netherlands, the households can separate plastic like bags, bottles and blister packagings and put that out next to the trash in a separate bag.
We assume they then will be recycled to new blisters and stuff alike.
Separating plastic, saves about 2/3 of trash at this household.
