What Is Food Waste?

Food waste is edible food that never makes it from farm to forkβ€”think perfectly good fruits, grains, and proteins tossed aside at any stage, from fields to store shelves to our plates. Wasted food squanders water, land, and labor, and in landfills it rots into methane, a greenhouse gas far more potent than COβ‚‚.

1.3B
tonnes wasted yearly worldwide
30-40%
of US food supply wasted
8-10%
of global greenhouse gases

Ingredient Stage

What happens: Farms and suppliers deliver produce, grains, dairy, and proteins to campus kitchens.

Water & Land Use
Growing food consumes vast water and occupies farmland
Transport Emissions
Refrigerated trucks burn fuel and emit COβ‚‚ en route
πŸ‘¨β€πŸ³

Kitchen Stage

What happens: Chefs wash, chop, and cookβ€”and routinely make extra "just in case."

Energy Waste
Unused batches still consumed electricity, gas, and embedded water
Embedded Loss
Every pound of trim or overcook wastes all the resources that created it
🍽️

Display Stage

What happens: Meals go out under heat lamps and chill wells, refilled on demand.

Heating & Cooling Load
Keeping food at safe temps spikes energy use
Portion Overshoot
Large self-serve scoops drive up plate waste and upstream footprint
🍴

Consumption Stage

What happens: Students take foodβ€”and on average leave 20-30% uneaten.

Methane Potential
Food in landfill emits methane ~28x stronger than COβ‚‚
Lost Nutrition
Uneaten meals could've fed someoneβ€”or composted
♻️

End of Life Stage

What happens: Scraps and spoiled items go in compost binsβ€”if correctly sorted.

Composting Wins
Properly diverted organics sequester carbon and enrich soils
Contamination Cost
Mis-bins spoil whole loads, sending them (and extra truck trips) to landfill

Cecilia Jiang - VP, UCSB Chinese Students and Scholars Association

A conversation about food waste from an international student perspective, exploring cultural values and systemic solutions

Interviewer: Allan Zhang Date: May 31, 2025 Location: UCSB Davidson Library

"In my family, wasting food isn't just 'bad', it's kind of shameful. There's this Confucian saying: '谁ηŸ₯η›˜δΈ­ι€, η²’η²’ηš†θΎ›θ‹¦' - every grain of rice comes from hardship."

"Students pile their plates because they have this subconscious idea: since I paid for it, I need to eat my money's worth. But they forget that what they don't eat, someone else could have."

"Without visible consequences, it doesn't register as a problem. There are no signs telling students: 'Here's how much was wasted yesterday.'"

"The biggest barrier is language and access to information. Composting bins are labeled with terms that don't exist in beginner English textbooks."

"We've started creating a bilingual digital zine called '吃得干净 (Chi De Gan Jing)' - Eat Clean. The goal is to make food sustainability culturally relevant."

"Sustainability doesn't have to be abstract. It can be about honoring food, community, and memory. When we connect those ideas, students feel like they belong in the movement."

Allan: Cecilia, thank you so much for making time for this conversation, and congratulations again on being elected as the Vice President of CSSA for next academic year. Watching you grow, not just as a student leader, but as someone who truly cares about sustainability and community impact, has been incredibly inspiring.

Cecilia: Thank you, Allan! It's been a journey, and I've learned so much along the way at UCSB, especially through the lens of sustainability. I never expected this would become such a significant part of my college life, but the more I saw what was happening around our campus about food waste, the more I felt like I had to do something.

Cultural Shock & Emotional Response to Food Waste

Allan: I wanted to begin with something we both probably experienced as international students from China - our first real exposure to the food waste culture here in the U.S. When I first entered the DLG dining common, I was genuinely shocked by the amount of edible food left untouched. What was your initial reaction to food waste when you arrived at UCSB?

Cecilia: I remember my first quarter at UCSB, I often sat near the dish return area in the DLG and literally watched students scrape entire meals into the trash - roasted meat, jasmine rice, cooked potatoes, and even whole desserts. For a moment, I was kind of frozen and shocked. Because in my family, wasting food isn't just "bad", it's kind of shameful.

Cecilia: There's this Confucian saying we grew up with: "谁ηŸ₯η›˜δΈ­ι€ (Shui Zhi Pan Zhong Can), η²’η²’ηš†θΎ›θ‹¦ (Li Li Jie Xin Ku)" - it means that each grain on the plate comes from hard work and bitter toil. That mindset comes from history. Our grandparents endured real famine, and for them, food equals security, love, and respect. So to witness food being treated so casually here felt like a culture clash.

Systemic Causes: Overproduction & Dining Culture

Allan: From your point of view, what do you think are the key reasons for persistent food waste at UCSB?

Cecilia: I'd say it's a combination of overproduction, student habits, and system design. On the production side, dining halls overprepare to avoid complaints and ensure availability until closing time. But that means large trays of food are discarded every night.

Cecilia: Then there's student behavior. The "all-you-care-to-eat" model encourages excess. Students pile their plates because they have this subconscious idea: since I paid for it, I have the right to take as much as I like, and I need to eat my money's worth. But they forget that what they don't eat, someone else could have.

Allan: I've also seen students treat the buffet like a taste-test station - they grab three or four different dishes, take a bite of each, and throw away the rest.

Cecilia: Exactly! And there's little real-time accountability. There are compost bins, but no signs telling students: "Here's how much was wasted yesterday, or this week." Without visible consequences, it doesn't register as a problem.

Cultural Palate & Dining Commons Taste Gaps

Allan: How do you see the mismatch between taste expectations and what's actually served affecting waste?

Cecilia: It definitely plays a role. Many students get excited when we see dishes like "General Tso's Chicken" or "Szechuan Noodles" in our dining commons. But once we try them, the taste is often overly sweet, too oily, or lacking in the spices we're used to. It's not that the food is "bad", it's just not what we expect. So people end up dumping their entire serving - not because they're careless, but because they're disappointed.

Cecilia: In Chinese meals, we don't usually mix everything on one plate. We start light, like soup or greens, and build toward heavier items. The one-plate buffet format sometimes overwhelms our appetite. It feels chaotic to the senses, and that impacts whether we finish our food.

Barriers for International Students

Allan: What do you think are some barriers that international students face when it comes to food waste and sustainability?

Cecilia: The biggest one is language and access to information. Composting bins are often labeled with terms like "biodegradable packaging" - these terms don't exist in beginner or intermediate English textbooks. So international students tend to ignore or guess, and often get it wrong.

Cecilia: There's also cultural hesitation. We don't want to be seen as overly critical or disruptive, so even if we notice issues, we think "it's not my place to say anything." Adding to the pressure of adjusting to a new country, it's easy to disengage.

CSSA's Cultural Sustainability Efforts

Allan: Can you share more about what CSSA has been doing in sustainability work?

Cecilia: We've started creating a bilingual digital zine called "吃得干净 (Chi De Gan Jing)" - which means "Eat Clean". The zine includes reflections on food stories from our hometown, sustainable tips, and interviews with dining staff who are also CSSA members. The goal is to make food sustainability culturally relevant.

Cecilia: We're also planning to collaborate with UCSB Dining to push for more Mandarin signage in compost stations and multilingual orientation materials. And we want to host monthly low-waste potlucks, where we showcase homemade dishes and emphasize not wasting ingredients.

Allan: That's brilliant! It's not just education, it's a celebration. It shows that food values from our culture can be part of the solution.

Cecilia: Yes! Sustainability doesn't have to be abstract. It can be about honoring food, community, and memory. When we connect those ideas, students feel like they belong in the movement.

Proposals for Campus-Wide Change

Allan: On an institutional level, what would you love to see UCSB implement to address food waste?

Cecilia: I'd love to see a Sustainable Eating Week, with waste dashboards in dining commons, cooking workshops, and incentives for students who reduce waste. We need visual data showing how many pounds of food we wasted yesterday or weekly - that makes the issue tangible.

Cecilia: I also believe in "Taste Testing Panels" for international dishes. Before putting new items on the menu, involve students from that culture to give feedback. It'll improve satisfaction and reduce waste from rejected dishes. We could add a tasting station where students can sample food before deciding whether to take a full portion.

Allan: Thank you again for being so open, thoughtful, and reflective throughout this conversation. I've always admired how you bring cultural insight and leadership together, and hearing you articulate the connection between food, memory, and responsibility has given me a lot to think about.

Cecilia: Thank you, Allan. Talking like this reminds me why these issues matter so much. It's not just about food, it's about how we live, how we take care of each other, and how we carry our cultures forward in meaningful ways.

Allan: I hope that by sharing your voice, more students will start to see food waste not just as a problem to fix, but as a question of values and community.

Cecilia: That's exactly what we need - seeing this as an opportunity to build bridges and create understanding across cultures while solving real problems together.

Brian Sun - Second-Year Data Science Student

An honest look at everyday dining habits and practical solutions for reducing food waste on campus

Interviewer: Allan Zhang Date: June 6, 2025 Location: UCSB Davidson Library

"It's easy to just grab whatever looks decent. You figure, 'Hey, I paid for this meal swipe, might as well try everything.'"

"If I don't see the waste, it doesn't feel like a big deal. The assumption is that it's being handled by someone else, so students don't really worry about it."

"There's this feeling of 'ooh, I want to try this and that,' but when you stack four different dishes on your plate, it's easy to lose track of how much you're taking."

"If there was a poster saying 'X pounds of food went to waste yesterday,' I'd stop and think before getting that second portion. Right now, it just disappears."

"I would set up a 'Taste Before You Take' station for international or experimental dishes. Just a tiny spoonful before committing."

Allan: Hey, Brian, thank you so much for taking the time to chat today. Before we move on, I just want let you know that this interview is part of my sustainability project on food waste issue at UCSB. And it'll be transcribed and included in my portfolio, not anonymous, but it's very casual, totally open conversation. Does that sound okay?

Brian: Yeah, for sure! No worries. I'm happy to help. Sounds interesting!

Campus Dining Experience

Allan: Okay, thank you bro, so to start us off, what's a regular meal experience like for you on campus? Like, which dining commons do you go to, like, and how do you usually decide what and how much to eat?

Brian: Most days I go to DLG or Carrillo, depending on where my classes are or who I'm meeting up with. I've been on the meal plan since freshman year, so I use it pretty much daily, definitely lunch and dinner, and sometimes breakfast if I'm up early. I kind of just walk in and look around. I don't go in with a plan or look at the menu beforehand.

Allan: I see, bro. So, do you stick to like one plate of food? Or do you like to try, like, different dishes in one meal?

Brian: It actually depends. If I'm super hungry, I'll just load up a plate with a bunch of food stuff all at once. Other times I'll grab something small to start with, and if I like it, I will go back for more, especially for ice-creams. But honestly, I usually grab a lot the first time just to avoid walking back and forth. Especially if there were new things I haven't tried before.

Allan: Yeah, I see. So like, it's sort of like: "take now, like, and decide later?"

Brian: Yeah, pretty much it is! It's not really intentional, but it's easy to just grab whatever looks decent. You figure, "Hey, I paid for this meal swipe, might as well try everything"

Understanding Food Waste Systems

Allan: Oh yeah, I agree with you. Yeah, thank you so much. And then let's move on to the next question. So, for me, I remember when I first arrived at our campus in my first year, I didn't know too much about where uneaten food ended up or what happened behind the scenes. So do you have that experience in your first year too?

Brian: Oh, for sure. I mean, when I moved in as a freshman, there was so much going on, like meeting people, figuring out class schedules, I didn't pay attention to the food system at all. I saw the big bins where you drop off your plates, but I never thought about what happened after that.

Allan: I see, so, were there any signs or orientation moments that explained it?

Brian: Maybe there were? But if there were, I definitely missed them. I don't remember anyone really explaining the food process, like whether leftovers get composted or donated, or what "compostable" even means. I think the assumption is that it's being handled by someone else, so students don't really worry about it.

Allan: Hmm, yeah, so like, that kind of "invisible process" makes it easier to disengage, right?

Brian: Yeah, if I don't see the waste, it doesn't feel like a big deal.

Personal Food Waste Habits

Allan: Yeah, okay. So, yeah, let's move on to talk about your own habits. Do you ever end up leaving food on your plate? Or and, what are some reasons behind it? Or like, would you mind like share some of them, like, at this time?

Brian: Definitely. I mean, I don't waste every meal, but it happens more than I'd like to admit. Sometimes the food just doesn't taste how I expected it to, like I'll grab some tofu or beef dish and it ends up being too salty, or kind of bland. Or sometimes I realize I was more thirsty than hungry, so I stop eating halfway.

Allan: Oh, that's interesting! Like, you know, the mismatch between what do you think, what do you want, and what you actually eat.

Brian: Yeah, exactly. And a big part of it is curiosity too. There's this feeling of "ooh, I want to try this and that," but when you stack four different dishes on your plate, it's easy to lose track of how much you're taking. Then you try a few bites and realize you don't actually like that.

Allan: Hmm, that's valid. Do you ever feel guilty when that happened?

Brian: Sometimes, yeah. But honestly, I think I've been kind of numb to it. It's so normal to leave behind half a serving or dump that side of mac and cheese that you didn't like. And when everyone around you is doing the same, it doesn't feel like a big deal, even if deep down you know it probably should.

Understanding Waste Systems

Allan: So when you scrape food into the compost bin, what do you think happens next?

Brian: I assume it gets composted, like, broken down and turned into soil or something. I don't know where exactly that happens or who does it, though. I've never seen signs or data about it, so I'm kind of guessing right now.

Allan: Ohh, yeah, that uncertainty is common, bro. If you knew your food went straight to a landfill instead of compost, would that change, like, how you eat?

Brian: Definitely. I think just knowing more about where it ends up would make me more mindful. Like if there was a poster saying "X pounds of food went to waste yesterday," I'd stop and think before getting that second portion, right now, it just disappears, there's no feedback loop.

Education and Awareness

Allan: Definitely! And Brian, I am just curious, have you ever had a class, club, or like campus at UCSB, like group talk about food waste? Or seen any efforts to educate students about food waste this specific issue?

Brian: Not really. I took an intro environmental studies class that talked about global food production and climate change, but not specifically about UCSB or our dining commons. And I haven't had friends or clubs bring it up. I've seen compost signs and maybe one or two events, but they're easy to miss if you're not looking for them.

Allan: Yeah, I see, so like, yeah, so there's kind of a silence around it, right?

Brian: Yeah. It's not that people don't care, it's just that it's not really part of the conversation, unless you're in a sustainability group. You probably wouldn't even know there is a problem.

Solutions and Ideas

Allan: Ohh, exactly, so based on that, what do you think would actually help you reduce waste on a like day-to-day basis?

Brian: Hmm, I am thinking of two things. First, smaller serving portions or sample scoops for unfamiliar foods. Sometimes I just want to try something without committing to a full serving. And second, I think seeing the numbers would help. Like a screen in the dining area that says, "We wasted 200 pounds of food yesterday." That would stick in my head.

Allan: Yeah, woo, that's like really interesting ideas and opinions, that's cool. So like, meanwhile, do you think like, would like peer behavior or social pressure play a role for solving this issue too?

Brian: Maybe. If I saw my friends being super intentional about not wasting food, I'd probably follow their lead. But right now, everyone's kind of on autopilot. We need something that breaks the routine.

Allan: Yeah, okay, and then it is the final question: If you were in charge of UCSB Dining for just one day, what's one change you'd make?

Brian: Hmm, I would say I'd set up a "Taste Before You Take" station for international or experimental dishes. Just a tiny spoonful before committing. And maybe a "Clean Plate" challenge where you get points or even a reusable mug if you consistently finish your meals. I mean, that may work.

Allan: That's really such a good idea. So, make it fun but like also impactful for our dining commons.

Brian: Yeah, exactly. It's not about shaming people, it's about giving us better options and some motivation to do better.

Allan: So, yeah, Brian, thank you again. This conversation really shows how much more we can learn when we just stop and ask someone about their everyday habits like you. I appreciate your honesty, and then it really adds depth to the project. And since it's the final week, so good luck with your finals, bro!

Brian: Oh yeah, you should thank me!

What Can We Do

Three levels of impact for meaningful change

πŸ‘€

Personal Level

  • Mindful Portions: Start small on your tray, then go back for seconds if you need more.
  • Sort Perfectly: Don't just pile everything at the recycling station.
  • Meal Planning & Shopping: Map out your week's meals and buy only what you'll useβ€”cutting dorm-fridge spoilage.
🏫

Student & Campus Level

  • Rescue & Volunteer: Drop packaged leftovers at Share Tables and sign up with AS Food Bank to collect surplus.
  • Join & Advocate: Get involved in the Zero Waste Committee or dining-services focus groups to push for more share tables, smaller scoops, and clear bin signage.
  • Peer Education: Host quick demos or social-media challenges showing zero-waste trays, proper sorting, and food-waste facts.
🌍

Future & Systemic Level

  • Data-Driven Forecasting: Lobby for dashboards that track daily meal counts and waste tonnageβ€”use real data to tighten production.
  • Policy & Infrastructure: Advocate for campus-wide bans on single-use plastics by 2030, more composting stations in residence halls, and expanded plant-forward menu options.
  • Research & Innovation: Innovation on smart portion-control tools, AI-driven prep forecasts, or campus-wide "FoodWasteTracker" apps that gamify reduction.
