Sustainability

At GreenSpace we are committed to sustainability practices that reduce our ecological footprint. Below are some of the measures we are taking to be sustainable, and we are always striving to improve these practices.

Product Containers

Our product containers are made of polylactic acid (PLA) which is a resin left over from processing corn. Corn is a renewable resource that is carbon neutral. Corn can be regrown year after year to make more PLA, and because it is a plant, it takes up carbon dioxide from the atmosphere when it grows. This is more than anyone can say for petroleum, which is what typical plastic containers are made from. The containers are also fully biodegradable, meaning they will break down in your trash or compost and will not accumulate in landfills. Here’s a great Smithsonian Magazine article if you want to learn more about PLA!

Carbon Footprint

Our carbon footprint is approximately 33 metric tons of CO2 per year. For this measurement, we used the Farm Carbon Calculator. For context, each American is responsible for 17 tons of carbon dioxide per year (Source: World Bank) and a regular passenger vehicle emits approximately 4.7 metric tons of CO2 per year(Source: EPA). We strive to find ways to reduce this footprint whenever possible. Right now our biggest carbon emission sources are driving and shipping. We assess this figure each year as our business grows in order to be aware of how we are contributing to the rise of atmospheric CO2.

Lighting

Our lighting system includes compact fluorescent and low power LED lamps, which draw much less power compared to high pressure sodium or metal halide grow lights. The lighting power usage makes up a tiny portion of our total power consumption. While they aren’t as energy efficient as simply using the sun, growing indoors provides many other advantages such as providing fresh produce year round and efficient use of space.

Vermiculture

GreenSpace has recently added 2,000 new friends to our facility – Red Wigglers! Vermiculture is a form of composting that makes use of worms to hasten the breakdown of carbon-basedĀ matter like vegetables and grains. Our worms eat only the best organic produce and cornmeal to give us organic worm castings that we use to fertilize our microgreens. GreenSpace has developed a partnership with Wholesome Living Marketplace, an organic grocer and health food store in Bedford, PA to take their vegetable refuse and waste produce that is past it’s prime for human consumption and feed it to our worms, closing another waste loop. The worms and worm tower are from Uncle Jim’s Worm Farm.
