“Composting is the natural process of recycling organic matter, such as leaves and food scraps, into a valuable fertilizer that can enrich soil and plants.”
Composting can seem difficult to start, especially for home gardens and kitchens. There is a lot of information online that can be confusing. Our goal is to implement more education and resources for composting around campus.
Types of Composting
This type of composting needs to be turned every few days to incorporate air, you need to leave lots of air space and keep the compost moist when you are turning it.
This type of composting takes almost zero effort. Differently from aerobic, all you have to do is throw your compost in a pile or composter and leave it for a year or more. However, in this form it is very easy for bacteria to form just like trash would in a landfill.
This composting is all about the worms. They do most of the work along with the oxygen and bacteria within the compost. They will eat all non acidic fruits and vegetables, and can break down waste from cows or horses as well. This is a good choice for compost because it has less of a smell and can be done indoors or outdoors.
Composting reduces waste, which makes us less dependent on landfills. It also reduces greenhouse gas emissions.
It promotes healthy plant growth.
It reduces our reliance on synthetic fertilizer.
It puts important nutrients back in the soil.
Enriches soil, helping retain moisture and suppress plant diseases and pests.
Reduces the need for chemical fertilizers.
Encourages the production of beneficial bacteria and fungi that break down organic matter to create humus, a rich nutrient-filled material.
Composting Scales
GVSU's Sustainable Agriculture Project
The SAP already utilizes compost in their practices. They use plants and other organic materials from the property for their compost. When the materials have broken down into compost, they are then combined with soils and seeds to create bountiful harvests. However, there is little opportunity for composting around campus. Many students do not understand how composting works.
Organicycle Curbside Composting- Grand Rapids
Organicycle offers pick-up composting for residents of Grand Rapids. Their service is similar to a typical trash or recycling pick-up: a truck picks up a large bin from the end of the driveway every week. However, these bins are full of compostable materials. This is a great opportunity for residents who want to compost but choose not to do it themselves. This service reduces the amount of organic materials going to the landfill.
GreenBack- Singapore and Malaysia
GreenBack creates and sells compost to farmers and residents in their region. The city-state of Singapore is densely populated, meaning there are small-scale and rooftop gardens with little space for composting. By selling compost, GreenBack is helping people grow healthy and plentiful plants and crops.
Stakeholders
Director, Office of Sustainability Practices
Yumiko stated that if we were going to incorporate vermicomposting on campus we would need to consider compensation for the person working on the compost on school breaks.
She also mentioned maybe a student intern would be a better option rather than a member of the farm staff, or making the compost portable and someone could take it home over breaks. She also suggested the idea of having a map with all the compost locations on campus.
Sustainability Manager, Laker Food Co.
Allysa mentioned that composting is a great way for students to minimize their impact on campus and contribute to a more sustainable food system.
She also said that one of the biggest obstacles to composting is the time guests believe it takes to sort waste. It takes less than 20 seconds to sort waste in our dinning halls. Her biggest piece of advice for the student body is to think about the impact food waste has on the environment.
Our Implementation Plan
Our plan for incorporating composting into campus starts with getting students involved and educating. In order to do this we want to first make a club or a sub-club of Farm club all about composting! We want to share with students that composting is easy and rewarding. In this club we would educate those interested about how you can compost in a dorm room, how to properly compost in the bins on campus, and work on a compost together at the farm.
Next we want to make a map of where all the compost bins are on campus and where the SAP is located. These would be put up all throughout campus and in residential buildings so students can not only be encouraged to compost, but know where to do it.
Finally, the last part of our plan would be to have a vermicompost right on campus for students to see and keep up with its progress. This would ideally be located in a science building or possibly in our greenhouse here on campus. In order to do this, farm members would need to be working on this all year round and during breaks the worms can be left alone for three to four weeks without being fed more food scraps.
Over summer breaks, either summer students participating at the farm or a SAP intern could help with the worms. This will allow students to see the big effect the worms have on compost and see how efficient they are, it would also allow them to see the farm club volunteers work on the compost and students could get some insight on how it works. We hope this would encourage more people to visit the SAP and learn more.
If your'e looking to save some money Vermicomposting is the way to go!
Depending on how large of a Compost your'e trying to make the price will vary.
Compost Method
Vermicomposting
Equipment/tools
Plastic bins ($20-$200)
Drill ($10-$130)
Screening Material ($15-$40)
Worms ($20-$250)
Trowel (5$-$20)
Extra cost/ materials ($100-$500)
Vermicomposting can range anywhere from just a couple hundred dollars to a thousand plus. If your'e looking for the cheapest option (not the best quality materials) it would be around $170-$200. For the best quality of materials you would be looking at $1,100-$1,150.
