About Smart composter
UN SUSTAINABILITY DEVELOPMENT GOALS
Empowered and Driven:
Delivering Solutions for Global Issues
Affordable and Clean Energy (SDG 7)
Our smart composite system can improve energy efficiency by making materials lighter and stronger. This can reduce energy consumption in transportation and buildings. If we integrate renewable energy sources like solar panels, we can also support clean energy solutions.
Industry, Innovation, and Infrastructure (SDG 9)
By using advanced materials and smart technology, our system contributes to innovation in industry. If it makes infrastructure more durable and efficient, it helps build resilient and sustainable systems.
Responsible Consumption and Production (SDG 12)
If we use recycled materials or design our system for recyclability, we can reduce waste. Smart features can also help optimize material use, extending the lifespan of products and promoting sustainability.
Climate Action (SDG 13)
A system that reduces emissions or energy use directly helps combat climate change. If we include features like thermal insulation or carbon capture, we can further support climate action.
THE STORY BEGAN
DESIGN STORY
Challenges
Compact Design for Urban Living: Designing a smart composter that is compact yet efficient enough for small living spaces such as apartments, without compromising performance.
Use Case
Use Case: Urban Apartment Dweller Name: Sarah Age: 29 Occupation: Graphic Designer Location: London, UK Living Situation: Rents a one-bedroom apartment with no garden Scenario: Sarah is environmentally conscious but has limited space and no access to outdoor composting. She cooks at home often and notices how much food waste she throws out weekly—mostly vegetable scraps, coffee grounds, and fruit peels. Problem: She wants to reduce her carbon footprint but finds traditional composting impractical in a small flat. She’s concerned about smells, mess, and the time it would take to manage it manually. Solution: Sarah buys a SmartCompost unit. It fits easily in a corner of her kitchen. She opens the lid and drops in her daily food scraps. The device automatically grinds and processes the waste, adjusting moisture and temperature via built-in sensors. She gets a notification on her phone when the compost is ready. Every two weeks, she collects rich, odorless compost from the drawer and gives it to her friend who gardens, or donates it to a local community garden via a built-in sharing feature in the app. Outcome: Sarah cuts down on waste, feels more eco-friendly, and becomes an advocate for sustainable living—even in small urban spaces.
Solution
Compact, Efficient Design: Develop a sleek, vertical unit that fits easily into kitchens or balconies. Use modular components to make internal systems (like mixing and heating) space-efficient.

THE PROCESS
PROTOTYPE DESIGN
The prototype is a compact, modern smart composter designed for indoor use. It features a sleek, recycled plastic exterior with a soft-open lid and a small LED display for status updates. Inside, it uses automated mixing, heating, and sensor systems to process food waste efficiently. An odor-control filter ensures it’s clean and smell-free, perfect for kitchens or small apartments. A bottom drawer collects the finished compost, ready for use. The device connects to a mobile app via Wi-Fi or Bluetooth, allowing users to monitor progress and get helpful tips. The design is simple, hygienic, and eco-friendly—making sustainable living easy in any home.
PLEDGE
Impact on the market
The smart composter has the potential to disrupt the home sustainability market by making composting easy, clean, and accessible for a wider audience—especially urban residents. It addresses growing consumer demand for eco-friendly solutions and supports global efforts to reduce food waste and carbon emissions. By combining smart technology with sustainability, the product appeals to both environmentally conscious users and tech-savvy homeowners. It also opens opportunities in sectors like smart home integration, waste management innovation, and green tech retail, positioning it as a timely and impactful solution in a market increasingly driven by sustainability and convenience.
RESULTS
FINAL PRODUCT
The smart composter project is designed to provide a clean, efficient, and automated way to manage food waste in modern households. The core of the process revolves around accelerating natural decomposition through smart technology.
Once food waste—such as vegetable scraps, fruit peels, coffee grounds, and leftovers—is added to the composter, the device begins breaking it down using a combination of heat, aeration, and moisture control. Built-in sensors constantly monitor the internal environment to ensure ideal conditions for aerobic decomposition, which relies on oxygen to break down organic material efficiently and without producing foul odors.
A mixing mechanism regularly stirs the contents, ensuring oxygen is evenly distributed and preventing clumping or rotting. A low-level heating element maintains an optimal temperature (typically around 50–60°C), which accelerates microbial activity and speeds up the composting process. Moisture sensors ensure the material isn’t too wet or too dry—both of which can slow decomposition. If needed, the system automatically adjusts airflow or mixing speed.
Over the course of a few days to a couple of weeks (depending on input and environment), the food waste is converted into dark, crumbly compost rich in nutrients. This compost is collected in a bottom compartment, ready to be used for houseplants, gardens, or shared with community gardens.
The process replicates what would normally take months outdoors—condensed into a clean, odor-free, and tech-driven indoor solution. This smart composting process not only reduces landfill waste but also gives users a visible, rewarding way to participate in sustainable living.
