— Composting—

“Working with Andrew has been an absolute pleasure and learning experience about turning food residuals into the most nutrient dense soil amendment. I am on my second bin in the comfort of my second floor apartment and this has been an amazing experience that will benefit the gardens”.

What is Compost?

A nutrient dense soil amendment. The end result of solid organic matter that has been decomposed in the process of composting.

Composting in Connecticut

Through best practices and continuous annual maintenance, at the end of exactly one year, finished compost is ready for your vegetable garden. Composting is the decomposition of solid organic materials, that within one year of maintenance transforms into humus (compost), a rich and nutrient dense soil amendment. This process recycles various organic materials otherwise regarded as waste products.

The earth has been having a tough time lately, due to such conditions as overflowing landfills, loss of rainforests, air/water pollution, chemical poisoning, soil erosion and disappearing ozone layer. Much of this is the result of how we live.

Thinking about or implementing change on a national or global basis can be overwhelming. We can start implementing small changes and and practices right inside of our homes, to our neighbors and our community.

Composting allows you to do something for the part of the earth you live with day by day: your own home. Composting follows basic values, such as putting things where they belong and not making a mess.

Black Rock Garden Structures LLC’s mission is sustainability. How we grow our food, raise our food and even how we discard our food. How will our role within our community presently benefit us as well as our next generation to come? When we cook, we tend to accumulate food residuals (scraps, peels, cores, egg shells, etc.) essentially that we wouldn’t normally eat. We tend to throw them in the garbage.

Our garbage then goes to landfills and refuse plants (power stations that burn garbage to produce electricity) where it can further cause a problem to our environment. 30% of our house hold garbage contains food residuals, valuable and renewable resources that can be diverted from our garbage and introduced into various composting systems.
