In With the Old, Out With the New: Reducing Waste By Reusing Gardening Supplies
Our Northeast Sustainable Systems Team at Spark-Y is working with three public schools in the Northeast Minneapolis area: Pillsbury Elementary, Northeast Middle School, and Edison High School. Our main focus at these locations is to work on repairing and optimizing the current sustainable systems at these schools, which consist of aquaponic systems at all three locations, as well as a community garden at the Edison location. These systems are used to introduce the students to the topic of sustainability in an engaging, hands-on manner; to provide the student body with the ability to learn more about both science in general and the skills needed for growing and farming; and finally to supply fresh, nutritious food to the school cafeterias.
Recycling is a concept near and dear to every environmentally conscious individual’s heart. But how is it used in the garden? We used recycling in two primary ways: composting and aquaponics. Composting is a way that we can take nutrients from unwanted or unneeded sources, such as weeds or dead leaves, and turn it into a treatment to better our soil. An aquaponics system also serves to recycle nutrients in an indoor environment. As the fish excrete Ammonium and Nitrate through their waste and gills, the plants uptake the nutrients and filter the water for the fish.
It is important to remember that recycling is only one of the “Three R’s”: Reduce, Reuse, and Recycle. This phrase, repeated to us over and over again, seems to have lost its meaning. Many Americans focus almost solely on the recycling aspect of this mantra, when the practices of reducing and reusing are equally, if not more, important. All three are incredibly important when working towards sustainability in our nation, but it should be emphasized that these three actions are listed in order of focus. In other words, you should attempt to reduce the amount of materials you use as well as look to reuse those items, and only then recycle them once the former two paths have been exhausted.
In addition to recycling, the Northeast Sustainable Systems Team has been able to effectively use the other two vital principles of reducing and reusing in aspects of all of our projects’ systems, with our main focus in these first few weeks on Edison High School. For example, when we first started working in the Edison High School garden we noticed that there were many items left by the previous year’s gardeners. These materials were then utilized to further support the garden’s structure and to aid plant growth, amongst other tasks. We have identified five main ways in which we reused the materials already present in our gardening space, thereby reducing the number of supplies we had to purchase and diverting useful items from the landfill.
Rather than purchasing all of our plants from a garden store, we decided to bring some plants to our on-site locations from the Spark -Y headquarters, specifically from the Urban Agriculture Lab, or UAL. The UAL was almost overflowing with unused plants, and the Spark-Y staff were more than happy to unload some onto us. We then transferred our newly-acquired army of tomatoes, peppers, chives, and longevity spinach to the Edison High School aquaponics system and outdoor garden.
After planting in the garden, we noticed some sheets of wire mesh which had been left on the outside of the fence. We decided to use this material to support the growth of our tomato plants. The wire mesh was bent into a circle and inserted into the soil around each tomato plant, allowing the stems to cling onto the wire and grow upward, rather than outward. This not only allowed the tomato plants to thrive, but also prevented them from spreading along the ground and overcrowding one another.
While digging up one of the empty beds, we discovered several large rocks that had been hidden under the soil. What at first seemed to be only a few rocks later turned out to be a very large number, and we soon amassed a large collection. We elected to lay them out as a border for the garden’s gravel path, keeping the smaller rock gravel from moving into the open soil and vice versa. Not only did this have a practical use, but it also increased the overall visual appeal of the garden.
Letter "E" Sign
After cleaning up some trash around the perimeter of the fence, we found a very odd bit of litter: a large piece of metal, shaped into the letter E. One side of the E was painted white, and therefore we have speculated that it had been a part of a sign once spelling “Edison.” More importantly, however, the other side of the structure made the perfect space to plant flowers. Thus, the giant letter was reused as a lovely planter for some yellow marigold flowers, representing one of Edison’s school colors.
Pea Plant Stakes
One of the plant varieties that we decided to grow in the garden were pea plants. These were placed around the inside edge of the fence and in some terraced, elevated planters. The seedlings by the fence would be able to wrap themselves around the slots in the fence, but the seedlings in the planters had no such support. In order to allow them to grow properly, we decided to stretch string down from an upper row of horizontal yarn. Then, taking some branches from a dead tree in our compost pile, we stuck some stakes into the planters’ soil and wrapped the string around them, pulling it taut enough to give support to the future pea tendrils.
Sustainable practices can be implemented not only at Spark-Y, but in all aspects of our lives. As we attempt to go about our day to day lives in a way that respects the planet, it should be remembered that even little acts can make a difference, and that we can all work towards a greener Earth
Michael Salzl --- “At my college house at the University of St. Thomas I recycle recyclables and compost my organics waste. I also reuse glass jars for storage and as cups, and I have greatly reduced, if not stopped, my consumption of meat and single use plastics.”
Jahir Aquino Moran --- “The way I use the Three Rs in my life is when I’m reusing old or full PC parts for my current PC . For example if there is no more space in it i would look for a old and full hard drive and delete any thing that was in it and use it also with cooling systems.”
Andy Angel --- “The way I use one or all three R’s, Reduce Reuse and Recycle is when we use old boxes and plastic bins from food for other forms of storage for other food instead of buying new plastic stuff. We save money and prevent from using a ton of new plastic.”
Erin Boehme --- “I have been a vegetarian for two years, and so have a reduced reliance on livestock agriculture: something that produces a great amount of carbon-dioxide and methane (contributing to climate change) and uses a mind-boggling percentage of the world’s freshwater supply. I have also recently been trying to reduce the waste I produce by bringing reusable bags with me when shopping, and using tupperware to transport food instead of plastic wrap and plastic bags.”
Natalie Dusek --- “In my own life, I try to reduce, reuse, and recycle in many ways. In my house we use a compost bin daily to recycle food scraps, using them to create compost, which newly growing plants can use for nutrients. Additionally, I have made many personal daily changes in my life to reduce waste. For example, one of my friends and I created DIY bee wrap to wrap food instead of using plastic wrap or plastic bags. These are just a few examples of the many ways I try to reduce, reuse, and recycle in my own life!”
Gabriel Cayetano --- “I am a part-time vegetarian when I am at my mom’s house because she is vegetarian. We also have a compost bin that we use. I have also salvaged and reused computer parts that still function.
