Every day, college canteens and hostels throw away large amounts of untouched food. At the same time, many underprivileged people outside the campus struggle for their daily meals. This mismatch between waste and need inspired my idea.

My idea is to create a Campus Food Waste Tracker & Redistribution App that connects campus kitchens with NGOs, volunteers, or local shelters. Using a simple interface, canteen staff can quickly log leftover food (e.g., “20 meal boxes ready”) before it is wasted. The app then alerts nearby NGOs or student volunteers who can pick it up and distribute it within a short window of time.

The app will use features like:

• Real-time notifications to NGOs/volunteers

• Pickup scheduling to avoid delays

• Food safety checks & expiry timers

• Impact dashboard showing meals saved from waste

Who benefits?

• Canteens/Hostels → Reduce food waste and costs

• NGOs & Volunteers → Easier food collection and distribution

• Communities in need → Access to meals that would otherwise be wasted

• Universities → Build a sustainable, socially responsible campus culture

This problem matters to me because I’ve seen how much food goes into the bin during hostel dinners while so many outside our campus go hungry. With this idea, we can create a win-win situation: less waste, more meals, and a more sustainable campus.

One of the most significant real-world issues that we deal with today is food waste, and it's something we witness on a daily basis in our own college cafeteria. Plates are frequently left half-full, and significant portions of prepared meals are discarded. This not only wastes money and resources, but it also contributes to environmental problems such as climate change due to landfill emissions. That is why I think addressing food waste on campus is a significant problem to solve

Gaps in the current solutions/market:-

Cafeterias usually do not keep proper food waste statistics.
Existing solutions are primarily based on composting, rather than prevention.

Students don't know their individual contribution to waste.

There are limited tools to enable kitchens to forecast demand effectively in real time.

Who stands to benefit?

Students → More sustainable campus, possible discounts/rewards for minimizing waste.

Universities → Savings on food purchase and disposal, enhanced reputation for sustainability.

Community & Environment → Lower landfill waste, decreased carbon footprint, possible donations to local food banks.

Why this issue is important to you?

As a student, I’ve noticed how much uneaten food gets thrown away in the cafeteria every day. It made me realize how much money, effort, and environmental resources are wasted. Solving this problem would help not just our university, but also the planet.

Technical details:-

Smart Cafeteria App/System:
Students pre-order or indicate meal preferences, helping kitchens predict demand.

Cafeteria staff input data on leftover/wasted food → system generates reports and trends.

AI/ML model recommends portion realignment and menu planning.

Gamification: Students are rewarded with points or discounts for completing meals, minimizing waste, or donating unused portions.

IoT Smart Bins: Waste bins have sensors that weigh food discarded
→ Data is fed into dashboard for staff.

Problem(real world issue): 

The food service and restaurant industry creates an enormous quantity of food waste, a large-scale worldwide problem. Such waste, in the form of spoiled ingredients and leftover food from customer plates, is generally disposed of in landfills. When it breaks down, it emits methane, a very powerful greenhouse gas and a contributor to climate change. For businesses, this waste is not just an environmental liability but also a major economic drain, representing lost resources and increased costs for waste disposal. A solution to this problem could be to convert the  waste into compost and reuse it to grow chemical-free and healthy food sources.

Gaps in the market:

• Lack of Convenient On-Site Solutions: Existing systems often fail to provide a simple, on-site method for restaurants to manage their food scraps.

• Space and Complexity Issues: Many composting solutions are too large, complex, or difficult to operate within the confined and busy environment of a commercial kitchen.

• Poor Operational Integration: The market lacks services that are seamlessly integrated into a restaurant's daily workflow, making adoption and consistent use difficult.

• Absence of Scalable and Easy-to-Manage Services: There is a significant gap for a solution that is both effective at an industrial scale and user-friendly for individual businesses.

Solution- Scrapcycle:

• Composting as a Service: ScrapCycle installs custom-made, industrial-grade composting machines directly in restaurants, providing a complete solution to manage food waste.

• Smart Technology: A dedicated app allows staff to monitor the entire composting process in real-time, offering valuable insights into waste generation.

• Revenue Generation: For an additional fee, ScrapCycle packs and sells the finished compost to local farmers and customers, turning waste into a profitable product.

• Sustainable and Eco-Friendly: This service offers a simple way for any restaurant chain to reduce its environmental impact, enhance its sustainability practices, and contribute to a circular economy.
   

Who Benefits?

• Restraunts and eateries: Reduced waste disposal costs , revenue generation , enhanced public image.
• The environment: Lowers carbon footprint and diverts waste from landfills.
• Local farmers and consumers: Acces to high quality, nutrient rich compost.

Why this matters to me?

I've always wanted to contribute to slowing down climate change and  to invest in environmentally sustainable business ideas , and this idea helps me do exactly that.

Have you ever wondered how much food gets wasted , not only from plates but directly from the kitchen (untouched food) ??? 

In most institutions/ offices/schools, food is cooked based on the number of students on campus /employees/workers ,not how many actually want the meal . And also , if based on number, then not on the no of items they want to eat. Hence, there’s a mismatch between what’s cooked and what’s consumed. 

The problem 

Food wastage is one of the world’s most pressing issues, with the United Nations Food and Agriculture Organization (FAO) estimating that nearly 1.3 billion tons of food is wasted globally each year, accounting for roughly one-third of total production. In India alone, around 40% of food produced is wasted annually, despite millions going hungry daily. While food waste is often associated with leftovers on plates, a significant portion also comes from overproduction in canteens, corporate offices, institutions, and schools where meals are cooked in bulk. The variation between what is prepared and what is actually consumed leads to bowls of untouched food being discarded. That’s lakhs of rupees down the drain and meals that could’ve fed thousands of people.(FSSAI) 15-20% of cooked food is wasted from private institutions due to over preparation.

Global food waste costs the world economy $1 trillion each year (FAO).

It's not just food we waste , it's litres of water, resources, hours of labour etc..

The solution

What if we could fix that- with one small habit change?

My idea is to create an app that allows individuals to pre-select their meals a day in advance. Employees, students, or residents would be shown the menu for the next day and can opt into specific dishes along with approximate portion sizes. This data would be collected and analyzed by the kitchen staff to prepare accurate quantities of each item, minimizing unnecessary cooking.

And yes! LESS OVERPRODUCTION! LESS WASTE! MORE EFFICIENCY !!

The technical backbone of the app would include real-time dashboards for kitchen managers, predictive analytics to track food preferences over time, and AI-based demand forecasting to improve accuracy further.

This innovation directly supports the UN Sustainable Development Goals (SDGs), particularly SDG 2 (Zero Hunger), SDG 12 (Responsible Consumption and Production), and SDG 13 (Climate Action), as reduced wastage lowers greenhouse gas emissions from discarded food.

Currently, there is a gap in the market—many institutions lack a systematic mechanism to match demand with supply. Some donate leftovers to orphanages or distribute food among workers, but large amounts are still wasted.

The benificials 

By adopting this app, institutions save costs on raw materials and cooking resources, while individuals benefit from having food they genuinely want to eat. Any small leftover quantities can be channeled more efficiently to workers or delivered to nearby NGOs.

This isn’t just about food, its about thoughtful consumption, better planning and helping people we may never meet.

If every student simply made a meal choice in advance, we could save food, money and lives- all with a single tap.

This problem resonates deeply with me because I have often witnessed heaps of untouched food thrown away while many people outside go hungry. Food is the most basic necessity—we work for it, and life revolves around it. With this app, I aim not only to reduce waste but also to ensure that resources are valued, hunger is alleviated, and sustainability is prioritized.

Have you ever bought a tub of Greek yoghurt and then forgotten about it? A week later, you find it in your fridge, already expired. Not only is this wasting your money, but it is also wasting food. If something like that ever happened to you, then this app is perfect for you. 

My idea:

My idea is to develop an app that tracks the expiration dates of groceries purchased by consumers. All the consumer has to do is scan the barcode of the groceries, and the app then adds it to its list. It sends reminders about any food expiring soon and also suggests dishes based on the ingredients available in the list. 

Gaps in the current market:

The current market doesn't really combine the barcode scanning of groceries with giving recipe recommendations. Also, this app will focus more on the products and companies found in the Indian market. 

Who benefits:

People who are forgetful about their groceries (like me) are gonna benefit a lot from this app. Apart from that, the general public can also use this app, which decreases food waste as people won't wait till their groceries expire. Reducing food waste is going to help everyone achieve a more sustainable world. 

Why this problem matters to me:

This problem matters to me because I see tons of food wastage around me daily, whether it be in the campus mess or in the general public. I believe minimum food wastage is going to benefit the people. This app is also going to minimise the financial waste from households, which will help them have a better budget. 

Technical details:

• Built with React Native (iOS + Android).
• Barcode scanning via ML Kit with a manual entry option for items without a barcode.
• Colour-coded expiry indicators and notifications.
• Recipe recommendations based on which product expires first. 
• For produce, it uses estimates of when it expires (eg: an apple 5-7 days).

OVERVIEW:


Food waste is one of the biggest hidden problems worldwide. Around one-third of food produced globally is wasted. A big reason is confusion about expiry dates. People throw away food that’s still edible because they don’t trust the printed “Best Before” label, and sometimes food spoils before the date, leading to health risks. You know how at home we always have that one conversation in front of the fridge: “Is this milk still good? Should we throw this bread?” I asked a few people about it, friends, family, neighbours, and almost everyone said the same thing. Either they throw away food too early just to be safe, or they risk eating it and sometimes regret it later.

GAPS:

-> Current labels only show an estimated date, not the real freshness.
-> Some companies are testing QR codes or apps, but they’re too complicated for everyday use.
-> There’s no simple, low-cost way for families or retailers to know when food is actually safe.

WHO BENEFITS:

Users (families, students, consumers): Save money by not wasting food and avoiding food poisoning.
Buyers (shops, supermarkets, restaurants): Reduce food wastage and losses, and donate food before it spoils.
Community & Environment: Less food waste means less methane emission from landfills, saving resources like water and farmland.

Why This Problem Matters to Me:

When I talked to family and friends, everyone had the same frustration: “Should I eat this or throw it away?” I realised it’s a small everyday problem, but one that adds up to a massive global issue. For me, engineering isn’t just about rockets and planes; it’s about designing smart, practical solutions that make daily life easier and reduce waste. That’s why this idea feels personal and meaningful

This idea matters to me because food is such a basic part of everyone’s life. I’ve seen people in my own family debate over whether something in the fridge is “still okay” or not. Sometimes it gets thrown away just to be safe, and sometimes we keep it too long.

I want to solve that everyday confusion with something simple and human-friendly.

Technical Details

The labels can be made with bio-inks and pH-sensitive gels that change colour as food spoils.
  -> Green = Fresh
  -> Yellow = Consume Soon
  -> Red = Spoiled

They’re safe, low-cost, and can be mass-produced for dairy, bread, fruits, and meat packaging.

The Problem

Food wastage in college messes is a persistent issue. Students often take more food than they can eat and then leave the plates untouched, while many other people out there are struggling to afford a proper meal. Despite the seriousness of the problem, current systems lack accountability and motivation. Messes only serve and clears food; they do not encourage mindful eating or have structured methods to redistribute excess.

The Solution

MessMate is a mess management software integrated with Face ID recognition. When students return their plates, the system scans them. If the plates are empty, students earn points, which accumulate over time. At the end of the semester, these points are redeemed as direct deductions from meal charges. This gamified reward system creates accountability and motivates students to take only as much food as they can finish.

For the unused but fresh food (not plate leftovers), MessMate offers two approaches:

1. Self-pickup parcel counters inside the mess – Students can collect hygienically packed meals or pack leftovers in their own containers.

2. NGO/Orphanage tie-ups – Surplus food can be donated daily to nearby NGOs, extending the impact beyond the campus.

Impact and Benefits

• Students: Save money on mess charges while developing mindful eating habits.

• Mess contractors/colleges: Reduce food waste, cut costs, and enhance their sustainability image.

• Community/NGOs: Receive fresh, unused meals for those in need.

Why This Matters to Me

I have personally seen kilograms of food wasted daily in my college mess. It feels wrong when so many people struggle to afford even one proper meal. MessMate turns waste into savings and social value, helping students, institutions, and the community simultaneously.

Technical Details 

• Face ID–based plate scanning system.

• Points tracking and automatic fee deductions.

• Waste analytics dashboard for administrators.

• Food safety compliance for redistribution.
