One Woman’s Trash is Another Woman’s Treasure: Composting Organic Kitchen Waste at Smith College Emily Edmonds-Langham EVS 300 – Peckol & White May 8, 2008 1 Abstract I began this project with the intention of exploring and further developing the relationship between Dining Services and the emerging Smith Community Garden (SCG hereafter) with specific attention to organic waste and composted material, in an effort to close the organic waste loop on the Smith Campus. The first step involved doing some research about both compost and community gardens: what makes good compost? Why compost? What is the value (both social and economic) of a community garden? I then conducted interviews with members of the staff and student body who were connected to the SCG in some capacity before ultimately visiting (and doing some work at) the Garden myself. I also arranged to visit the Hampshire College farm in order to compare their composting system with our own program. As a result of my work, I discovered that we produce an incredible amount of organic waste, both in the kitchens and on the grounds, and therefore are capable of creating far more compost than we will ever feasibly use. I was surprised to find so much composting already under way, as well as fairly well developed plans for expansion. Currently, our kitchen waste slated for compost is outsourced to a farm in Greenfield, but there are plans to bring the operation closer to home. I think it is important that the SCG be able to take advantage of this compost, which will provide different nutrients than the compost created by our yard waste and horse manure that they are currently using. 2 Introduction The fifteen dining rooms on campus, while wonderful for fostering a sense of community, are responsible for a hefty portion of Smith’s waste stream: the kitchens produce ⅓rd of our landfill waste every year, weighing in at 300 tons of material (Dombkowski 2008). Luckily, not all of the organic waste produced on campus is slated to sit in a landfill: the Grounds Department deposits our yard waste at a compound at the Fort Hill site, located just off of South Street. The massive piles of leaves, grass clippings, and horse manure (200-300 cubic yards’ worth every year) decompose and provide roughly 100 cubic yards of compost (Dombkowski 2008). In addition, Dining Services has spearheaded a composting program in the Cutter/Ziskind and Chase/Duckett dining halls. Compost is clearly alive and well at Smith College, and shows promise for future expansion. One of the fundamental questions all this composting poses is why compost at all? The simple answer is that this process diverts some of our waste from the landfill, giving materials a chance to decompose and provide beneficial nutrients to the soil. J. I. Rodale posits in his comprehensive Complete Book of Composting that, “In the soft, warm bosom of a decaying compost heap, a transformation from life to death and back again is taking place. Life is leaving the living plants of yesterday, but in their death these leaves and stalks pass on their vitality to the coming generations of future seasons. Here in a dank and mouldy pile the wheel of life is turning” (Rodale 1975). While Rodale perhaps romanticizes the process, he hits on something essential: by composting, we 3 “close the loop” between the produce we eat which draws nutrients from the soil, and replenishes the environment through the decay of parts of that same produce, thus renewing the soil’s ability to provide for a new crop. It is the health of these new crops that I am particularly interested in, as Smith gets its own Community Garden off, or rather into, the ground. Michael Pollan also provides a convincing argument for composting in his recent New York Times Magazine article urging us all to do our part, however small: “[I]n a thoughtfully organized vegetable garden (one planted from seed, nourished by compost from the kitchen and involving not too many drives to the garden center), you can grow the proverbial free lunch — CO2-free and dollarfree” (Pollan 2008). Through our composting program, we have the potential to produce at least a few “free lunches” as we recycle and repurpose our own waste. The idea of eating as locally as possible is gaining traction in our petroleum-based society, and Smith certainly ascribes to the notion of buying local produce whenever possible. Barbara Kingsolver shares her family’s experience with eating locally for a year, pointing out their place in a larger trend in Animal, Vegetable, Miracle: Something positive is also happening under the surface of our nation’s food preference paradigm. It could be called a movement. It includes gardeners who grow some of their own produce—one-quarter of all U.S. households, according to the U.S. Census Bureau. Just as importantly, it’s the city dwellers who roll their kids out of bed on Saturday mornings and head down to the farmers’ markets (Kingsolver 2007). The desire for a community garden expressed by the students, faculty, and staff involved with the SCG project is not unique; the writers of the SCG proposal 4 recognize their place within a larger tradition: “We believe the tradition of the Victory garden needs reviving, as a patriotic and proactive avenue for current Smith students to ‘do their part’ in the fight against global climate change” (SCG 2008). In supplementing the College’s produce with some of the home-grown variety, we not only save money, but also reduce emissions of green house gases that would have been released in the transport of produce from far-flung locales. Community gardens provide a number of benefits: fresh produce is not the only end result. In the introduction to The Meaning of Gardens, Mark Francis and Randolph Hester, Jr. discuss the value of the community garden: Community gardens result in part from a growing reaction to the privatization of public life and the need for spaces that support social contact and publicness. They also spring from an increased interest in places that invite and inspire ongoing change and modifications through public stewardship and local involvement (Francis and Hester, Jr. 1990). They provide a balm for our increasingly isolating society, as well an opportunity to come together and generate results one can see. A functional garden requires the work of many hands: as a result, it motivates cohesion within a community. Kate Brown and Andrew Jameton discuss the physical benefits of gardening in their article in the Journal of Public Health Policy: “…[P]lants and gardening contribute to an improved quality of life and overall health. For example, recreational gardening has been observed to be a way to relax and release stress” according to research done by the Plant-People Council (Brown and Jameton 2000). Smithies, and college students in general, are always in need of 5 ways to relieve stress. What better way to do so than to spend some time in the Garden? My goal in researching this topic was to learn about our composting efforts on campus and to discover the source of SCG’s compost. Armed with this information, I hoped to make suggestions about building a relationship between organic waste producers on campus (the dining rooms) and the end user of the composted waste (the SCG). I was also very interested to learn about Hampshire College’s efforts and hoped it would provide a useful model, owing to the fact that it is a long established and successful student initiative. I think achieved my research objectives. Methodology Interviews: I set out intending to interview people involved with either the SCG or the composting effort in different capacities, whether as a member of the Smith College staff or as a student. After contacting Hannah Wren Dunning, a student involved with the set-up of the SCG, about a possible meeting, Hannah gave me access to the Garden’s email account for research purposes, which allowed me to better prepare for later interviews. I then emailed both Kathy Zieja of Dining Services, Bob Dombkowski of the Grounds Department and Leslie Cox, the Manager of the Hampshire Farm to learn more about current levels composting on both our campus and that of one of the other Five Colleges. Before meeting with any of them, I drafted a comprehensive list of questions and points I hoped to address in my conversations with all of the subjects of my interviews. Kathy redirected my enquiry to Ann Finley, who works beneath her but also serves on 6 the Sustainability Committee on campus and would be an ideal person to discuss composting in the dining rooms with. They were both incredibly supportive and excited about the SCG. Ann also sent me in search of E.J., one of the cooks, who is a serious gardener and who was pleased to recommend the very helpful Complete Book of Composting, published by the Rodale Press. I visited the SCG at their Fort Hill site during their weekend work days (April 25 and 26) and talked to a number of people involved in the effort. I photographed the goings-on there, as well as taking part in some bed-digging myself. On the first day, I spoke to Marianna Ballou and Mandy Lineweber, and caught up with Hannah Wren Dunning on the second. They gave me a helpful history of the Garden, as well as shared some concerns and issues the organization faced, and outlined future plans. I also visited the Hampshire Farm for comparison, and there conducted my interview with Leslie Cox who graciously showed me their composting operation. Textual Research: The epic tome, The Complete Book of Composting, turned out to be the tip of the composting iceberg: Forbes has a very helpful collection of books about setting up a home compost system which I found very helpful in my research. I also requested a number of books from the Five College library system, some of them government publications, about establishing community gardens and assessing their social as well as economic value. I looked at some gardening memoirs, especially Barbara Kingsolver’s Animal, Vegetable, Miracle, with the hope of finding more personalized accounts of what brings people back to the vegetable garden. Some of these memoirs were more useful than others: turns 7 out Compost College has very little to do with composting after all, but rather recounts one man’s experience living in a commune by that name in Northern California in the late 60s and early 70s. Alas! In addition, I found Michael Pollan’s New York Times Magazine article, “Why Bother?” very timely and helpful for providing background information about making an impact. Results Yard Waste: As noted above, the campus produces a vast amount of yard waste every year; currently there are 400 cubic yards of compost at the Fort Hill site, pictured in Figures 1-3. Bob Dombkowski attempted to give me a sense of the 100 cubic yards of compost we produce annually, saying, “I could cover the ITT with feet of compost” (Dombkowski 2008). The Grounds Department, in conjunction with the Lyman Botanic Garden, only uses about 50 cubic yards of the finished product annually; this useable material is shown in Figure 3. These piles must be maintained, which involves the occasional turning of material. Stu Campbell summarizes the task of turning one’s pile in Let It Rot!: “Turning your pile is the only ‘bummer’—the only real chore in the whole business of compost making. A cubic yard of finished compost weighs about 800 to 1100 pounds; compost-inthe-making weights slightly less” (Campbell 1998). Luckily, Bob and his crew have heavy machinery for this chore. Leslie Cox can be seen performing this task on Hampshire’s compost in Figures 4 and 5. As you can see, they have significantly less backlog – but they also have a fully operational 125-acre farm to make use of this material. Kitchen Waste: 8 The story of Smith’s composted kitchen waste is much more complicated, even though the program is relatively small. While currently we send 300 tons of kitchen waste to the landfill every year, the compost program diverts some of that waste. At present, the collection of our organic waste falls to the Alternative Recycling firm, which is based in Leeds. Their service picks up plastic bins full of waste three times a week: they provide bins and bags, shown in Figure 8. The system does not require a change in behavior from the students, who are already used to scraping their plates into a bin, such as the one in Tyler (Figure 7). This material then goes to a farm in Greenfield to be composted, at a financial cost to the College. The composting program provides an educational opportunity: dos and don’ts of composting are posted in the dish windows, as shown in Figure 9. Dining Services also took part in the Sustainability Workshops which were part of First Year Orientation this fall. Ann Finley discussed the current composting program with the class of 2011, and detailed what Dining Services specifically is doing to address the issue of sustainability in the dining rooms (Finley 2008). The composting program is much more professional than its previous incarnation, which was based in the Quad and was a student initiative. Ann Finley laid out the history of this past effort: seven years ago, a group of students attempted to collect some of the Quad’s organic waste for compost. They acquisitioned a pickup truck from Physical Plant (which occasionally broke down), and picked up the material themselves once a week and deposited it at the Smith Vocational School where it would ultimately decompose. However, due to the fact that student availability fluctuates greatly over the course of the 9 semester, the service was irregular at best – and one cannot afford to be irregular when there are rotting banana peels involved. This problem does not persist under the current program, which began in December 2006 in Cutter/Ziskind and January 2007 at Chase/Duckett (Finley 2008). The Smith Community Garden: The SCG represents a much more successful student initiative: after a search of only one year, the group found a site and will have seedlings in the ground for harvest this summer and fall. The space allotted to them at Fort Hill is a former playground, and therefore initially lay under 18” of mulch which had to be removed before seeding the beds. For an illustration of the de-mulching, refer to Figure 12. The Garden measures 137’ by 51’ and the group has dug six 18” raised beds, which can be seen in Figure 10. The beds will be reinforced with the board frames which are being prepared and completed in Figure 11. Bob Dombkowski will provide truckloads of loam once the beds are prepared to receive it (Dombkowski 2008). Because the Garden is at Fort Hill alongside the composted yard waste, they already have a convenient source of compost. However, all compost guides stress the importance of having a multitude of ingredients in the perfect compost. For example, Campbell provides the following list of items ideal for compost: [I]t is worth mentioning some of the things you are most likely to get your hands on without spending a great deal of time and money. These might include ashes, feathers, garbage, grass clippings, ground stone and shells, hedge trimmings, hopes, leather waste, newspaper, peat moss, pine needles, sawdust, seaweed, sod, and weeds, among others (Campbell 1998). 10 While the compost produced by the yard waste has some of these components, it would be beneficial to the soil to have a more complex mix of compost. Leslie Fox rightly referred to the pile in Figure 6 as his “carbon pile,” for hay serves primarily as a carbon source in the compost world. Better to balance this with kitchen waste in the eyes of Robyn Bem: “The various vegetable and fruit trimmings available in households, groceries, and restaurants are rich in nitrogen and other nutrients,” providing examples such as banana skins (high in potassium, phosphorous, and nitrogen), citrus rinds (the thicker they are, the more nitrogen they possess), egg shells (calcium), and peanut shells (nitrogen) (Bem 1978). The combination of these ingredients makes for healthier soil and happier plants. The SCG intends to plant a wide variety of fruits and vegetables in their six beds: Marianna Ballou and Mandy Lineweber listed carrots, beets, eggplant, lettuce, watermelons, pumpkins, peppers (chili and bell), and tomatoes in rapid succession as some examples of what they intended to produce this summer and fall. There has also been talk of a canning operation so that students can continue to enjoy the fruits of the Garden’s labors throughout the year (Ballou and Lineweber 2008). Kathy Zieja, for one, is very excited about serving their squash in the fall and intends to have a harvest dinner supplied by SCG produce in the fall (Zieja 2008). One of the major hurdles standing between the SCG and harvest time is the issue of water: the spigot adjacent to the plot does not work, but they hope to get it examined by a plumber soon and will rely on the kindness 11 of another building for now until the problem is addressed (Ballou and Lineweber 2008). Another problem facing the SCG, which has been resolved in the short term, is that of summer care. This summer, four students have volunteered to stay on and tend the beds, but this is not a solution that can be relied on in future years. While establishing a PRAXIS internship or two was initially explored, the Garden leadership discovered that students cannot receive that particular stipend because the Garden is situated on property that the College owns (Dunning 2008). Hampshire has solved this problem by allocating funds to hire a summer staff, which draws not only from both the Hampshire and larger Five College student bodies, but is open to all interested parties (Cox 2008). Due to the growing trend of environmentalism and eating organically, I am sure that Hampshire has no problem filling these spots. Both the composting going on at Smith as well as the SCG effort reflect this trend, as does my examination of the issue in the first place. The presence and continued great work by the Sustainability Committee encourages my believe that Smith is doing its part for the environment, or at least attempting to implement schemes that move us closer to doing so. 12 Tables and Figures Figure 1.

According to the Massachusetts Department of Environmental Protection, “[F]ood waste accounts for at least 10 percent of all municipal solid waste generated in the state, or nearly 900,000 tons per year” (DEP 2005). They use this figure as encouragement for home composting of kitchen waste. America is catching on, and not just in Massachusetts. Campbell breaks down these figures further, but instead works with the national average, writing, “The volume of yard waste we generate works out to about 230 pounds per person per year. Food waste adds another 100 pounds per person per year … It’s estimated that all residences could reduce their total annual volume of waste by 35 percent if they composted at home” (Campbell 1998). Here at Smith, especially in light of Dombkowski’s revelation that food waste accounts for ⅓ rd of our waste on campus, it is clear than an effort is being made to reduce our landfill deposits as much as we possibly can. We have certainly made impressive progress. With the addition of the SCG to our resources, we find an end-user of our composted organic material within our own community. Bem provides a wonderful description of this end result that should make us proud to be using it: Scoop up a handful of your compost. It should feel loose and crumbly. The compost should be a dark brown color and smell earthy and pleasant. Look closely at the compost in your hand. Some of the organic materials have decomposed completely and turned to humus—the dark uniform-looking substance of the compost. … The compost you have made will substantially enrich your garden soil (Bem 1978). 19 If this passage doesn’t inspire you to compost, I don’t know what will. The SCG has the capacity to absorb some of the compost produced by both our yard waste and kitchen waste, especially if our dining room composing program moves to a site closer to home. Dining Services, in conjunction with both Physical Plant and the Grounds Department who provide funds and labor respectively, has high hopes for the future of the program. Currently, they are hard at work with a local farmer, attempting to secure a permit from the state to expand their composting operation. As of July 1st, the Grounds Department is no longer responsible for the removal of waste from Smith’s various tenanted properties, which will free their schedule for increased pick-up of material destined for compost. Once the permit is acquired, the new operation will be within five miles of the College, and therefore our staff can collect and dispose of the material and allow us to terminate our contract with Alternative Recycling. The College already owns a truck that has been retro-fitted with the parts necessary for this kind of work, and would very much like to put it to good use (Dombkowski 2008). Once all these pieces are in place, Ann Finley expressed a desire to expand the program beyond Chase/Duckett and Cutter/Ziskind to encompass the entire campus, thus increasing our sustainability (Finley 2008). This planned expansion also provides increased educational opportunities. Ann Finley also discussed a plan to continue to incorporate sustainability discussions into First Year Orientation, as well as an idea to describe the composting program in the first House Meetings of the year as a 20 way to raise awareness (Finley 2008). Part of what makes Hampshire’s program so successful, according to Leslie Cox, is the level of awareness on campus, which he estimates at about 70% (Cox 2008). When I began this project, I had no idea that any dining room composting was going on, as it was all happening on other parts of campus that I do not visit frequently. Awareness must be at the center of any plan to expand this program, for many students do not know what materials are appropriate for compost, such as those listed by Campbell in the “Results” section. Finley estimates that the compost created by one dining room would be enough to cover the soil-enriching needs of the SCG (Finely 2008). As seen in the reduction that occurs in the yard waste (200-300 cubic yards of material breaking down into 100 cubic yards of compost), it takes a fair amount of raw material to create healthy compost. Luckily, the kitchens produce an incredible amount of organic waste which are more than capable, according to Bem cited above, of becoming a well balanced compost mixture. When mixed with the compost from the Fort Hill site, the SCG should be the proud possessors of fine soil. On the whole, we produce far too much compost to be significantly absorbed by the Garden, but it certainly meets their immediate needs. In the future, the SCG hopes to be an educational resource for courses across the academic spectrum. According to their proposal, … art students can sketch tomato vines, engineering students can work on plans to improve irrigation through rain water collection, or chemistry and biology students can study the soil composition. The Garden can be used in classes like Lisa Armstrong’s Feminisms and the Fate of the Planet, or Leslie King’s First Year Seminar, 21 Science and Politics of Food, Water and Energy. The possibilities for scholarly and practical application are endless (SCG 2008). A garden provides many and varied opportunities to learn about agriculture, food production and distribution, and the social context within which these systems operate. So much of the learning that occurs during a student’s time at Smith takes place outside of the classroom: the SCG provides yet another setting for extracurricular learning. According to a garden guide published by the United Nations, “Gardens are good for learning: they are a highly practical and direct form of education, where children can see the results of their decisions and actions. … Apart from practical skills in agriculture and horticulture, gardens are a living laboratory for the study of environmental issues and life sciences” (UN 2005). Of course, students at Smith are not children, but we still have much to learn. Practical knowledge, paired with the health benefits of gardening cited above, provides Smithies with resources they can take away with them for life after Smith. The Hampshire Farm model provides more valuable lessons to learn: they deal with the summer help issue by allocating funds for crews of summer interns. If the Garden is going to last, it will need the full financial support of the Organization Resource Committee, with enough funding to provide an adequate stipend to summer interns similar to the PRAXIS program. On-campus housing arrangements must also be made for these interns: the $2000 PRAXIS stipend (or its equivalent) does not stretch as far as one might think. The difficulty in comparing our SCG to Hampshire’s Farm arises in the scale of the operation: we will be planting six small beds, while Hampshire cultivates 125 acres, growing 22 both hay and vegetable crops. As a result, they are much better at absorbing their compost: there wasn’t any ready-to-use compost pile when I visited because all 1,200 tons of material had been distributed on the fields the week before. However, Leslie Cox is interested in expanding Hampshire’s composting capabilities. He called their current operation “pretty primitive,” expressing a desire to invest in larger machinery capable of handling much more waste (Cox 2008). If Hampshire is successful in expanding its operation, perhaps we would be interested in collaborating with them and sending some of our kitchen waste there. Unfortunately, such expansion may still be a few years in the future for them, as this machinery is incredibly expensive. Because the Hampshire land, in part, is technically a farm, they were grandfathered and did not have to go through a very difficult permitting process regarding their composting. Rather, the Massachusetts Department of Agricultural Resources checks on them once yearly. While we may not be ready, as a culture or a campus, to “wring most of the petroleum out of our food chain, even if that mean(s) giving up some things” in the style of Barbara Kingsolver, we are making discernible progress in that direction (Kingsolver 2007). With the founding of the SCG, we will be able to supplement our produce with fruits and vegetables that were grown right here on campus. These crops will be nourished by the composted remains of organic wastes produced by Smith’s own trees, lawns, and horses, as we attempt to absorb and repurpose our organic waste. By returning nutrients to the soil via 23 compost, we prevent material from ending up in landfills, where its chances of decomposing as it ought are slim due to the lack of light, air, and water in landfill systems. The value of a community garden cannot be stressed enough. Already, it has drawn people from all ends of the administration and student body together, and in conjunction with the efforts of the Sustainability Committee and the composting program, provides many opportunities for idea sharing. The sustainability effort is an integrated one: to truly make an impact, we must modify our behavior in all aspects of our lives – not just in our food choices. Education remains central to any effort to reduce our impact upon the planet: here at Smith, we are uniquely situated to both educate and be educated about these issues. The SCG provides an incredible amount of educational opportunities, and I share their hope that it will be a resource for many academic departments. The composting program also calls for a wider dispersal of information, much more comprehensive in scope than the small signs posted in the dish windows of Figure 9. Ann Finley’s idea of incorporating sustainability information into the first House Meeting of the year is a worthwhile one; perhaps the Earth Representatives elected by each house could also share the responsibility for this particular task of education. If the issues faced by these two endeavors are seriously addressed, both the SCG and the kitchen composting program will enjoy tremendous success and longevity. 24 Works Cited Ballou, Marianna and Mandy Lineweber.
