WasteWays

Inspiration

For every 1 ton of crop harvested, approximately 800kg of agricultural waste is left behind. This waste is often seen as a burden—leading to illegal burning, soil degradation, or costly disposal. We were inspired to flip the narrative: what if that 80% wasn’t "waste," but a diversified portfolio of sustainable resources? WasteWays was born to help farmers navigate this transition and tackle the waste crisis profitably and sustainably.

What it does

WasteWays is a decision-support tool for farmers to optimize the lifecycle of agricultural byproducts. It features an interactive Usage Distribution interface that allows users to:

Visualize the split between different processing methods (Animal Feed, Biogas, Biofuel, Fertilizer, and Biochar).
Dynamically balance ratios to see how a harvest can be diverted into different revenue or sustainability streams.
Get immediate feedback on how localized processing can reduce their environmental footprint.

How we built it

The platform is built using a modern, responsive stack:

Framework: React with Next.js for a seamless, "app-like" web experience.
Styling: Tailwind CSS for the UI, utilizing Shadcn/UI components for a clean, professional aesthetic.
State Management: Custom React hooks to handle the complex logic of redistributing percentages across multiple variables (ensuring the total always equals 100%).
Icons: Lucide-React to provide intuitive visual cues for different waste-processing categories.

Challenges we ran into

One of our biggest hurdles was the UX of math. Creating a slider that controls five variables simultaneously is difficult; when you increase "Biogas," which of the other four should decrease? We had to develop a redistribution algorithm that felt "natural" to the user. Additionally, researching the financial Cost and Co2 Emissions for every crop and every waste handling method was extremly difficult, since there wasn't a single source of truth for this to rely on.

Accomplishments that we're proud of

Interactive Fluidity: We built a custom "Multi-Slider" from scratch that allows for complex redistribution of data with simple drag-and-drop gestures.
Simplicity: Turning a massive environmental problem (800kg of waste per ton) into a manageable, visual interface that any farmer can use without a manual.

What we learned

We learned that sustainability is a balancing act. By building the distribution tool, we realized that there isn't a "one-size-fits-all" solution for waste; the best approach depends on the farmer's specific needs—whether they need energy (Biogas), soil health (Biochar), or immediate livestock support (Animal Feed). We also gained a deep appreciation for the technical nuances of touch-based interactions in web development.

What's next for WasteWays

Impact Metrics: Integrating real-time calculations to show CO2 offset and potential ROI based on the selected distribution ratios.
Localization: Adding data layers for local market prices of Biofuel and Fertilizer to help farmers choose the most profitable "WasteWay."
IoT Integration: Connecting with farm sensors to automatically input waste tonnage data.
