Worms
can turn almost anything into rich, useful garden
fertiliser. At home, worm farms can recycle all
fruit and vegetable scraps. In addition, the bins
are made from 100% recycled plastic, including old
banknotes and car battery casings. Commercially,
the much larger Vermitech system uses huge worm
farms to treat the sewage from humans and piggeries.
It produces valuable fertiliser for use on golf
courses, stud farms and wineries.
