I work at the School of Education in Mathematics Education and teach on PGCE and Master's courses and supervise several PGRs. I help to run the School's Climate Action Group. I have a family with 3 children, two of them still at school.
My challenge
I want to document (and hope to reduce) all my landfill waste.

But this, I am afraid, was left over from last week’s recycling (ie it was not collected) and so is my first item of the month to the landfill … not even really sure what it is …
