The message
from "Lucy & Howard Albert" contains
these words:

I've come up with a potential business idea to compost grass clippings and
leaves, using disposable plastic bags as the composting containers, rather
than composting stations.

The idea is to add a (secret) formula to compostable waste and turn it into
a useful garden material over several weeks of passive exterior storage,
without the exertion of rotating or emptying storage bins.

Bad.

Gardeners have been doing that ever since the plastic bag was
invented. What's more the "secret formula" isn't secret, and nobody can
produce it cheaper than we.

Janet.
