AVARTANAM : ICWIM
Turning waste into wealth: Rewarding responsible waste management for a cleaner, greener future.
The problem AVARTANAM : ICWIM solves
The Problem It Solves :
Waste mismanagement is a growing environmental challenge, especially in urban areas with rising populations and industrial activity. In India, improper waste disposal has led to clogged landfills, polluted water bodies, and increased greenhouse gas emissions. Despite government efforts to promote waste segregation and recycling, significant gaps remain due to several challenges:
Lack of Awareness: People often underestimate the importance of waste segregation and proper disposal.
Insufficient Incentives: Without tangible rewards, there is little motivation for individuals to adopt responsible waste management practices.
Inefficient Systems: Unorganized waste collection and disposal systems make recycling and repurposing waste difficult.
The Solution :
AVARTANAM: ICWIM (Initiative to Convert Waste into Money) provides a practical, reward-based approach to solving waste management challenges. It incentivizes households to participate actively in waste segregation by offering tangible benefits like tax relief, making the process simple, efficient, and rewarding.
How It Works:
Waste Segregation: Households separate waste into categories like organic, inorganic, and plastic.
Weighing and Point Allocation: Collection vehicles equipped with advanced weighing systems measure waste and allocate points based on type and weight.
QR Code Tracking: Each user is assigned a QR code to track their waste contributions.
Mobile App: A user-friendly app tracks contributions, monitors point accumulation, and allows users to redeem benefits.
Tax Relief: Accumulated points can be redeemed annually for house tax deductions, providing direct financial benefits.
Benefits :
For Individuals: Rewards make waste management an appealing habit while reducing expenses.
For the Environment: Reduced landfill use, increased recycling, and decreased pollution.
For Governments: Efficient waste systems with reduced costs and additional revenue from recycled materials.
Challenges we ran into
Challenges We Ran Into
Building AVARTANAM: ICWIM (Initiative to Convert Waste into Money) was a rewarding experience, but not without its fair share of challenges. Each stage of the project presented unique hurdles that tested both our hardware and software skills.
- Sensor Calibration and Accuracy
One of the critical tasks was achieving precise weight measurements using load cells. During testing, we noticed significant fluctuations in readings caused by environmental factors like vibration and inconsistent sensor calibration.
Solution:
We tackled this issue by implementing a real-time calibration system using a reference weight for initial setup. Additionally, we added code to filter noisy signals and used averaging algorithms to ensure consistent measurements.
- Integrating Hardware with Software
Integrating the ESP32 microcontroller with the load cells and QR code scanner was initially challenging due to communication protocol mismatches and debugging serial communication issues.
Solution:
We used a step-by-step debugging approach, checking each component individually before integrating them. Adjusting the baud rate and implementing efficient protocols resolved communication bottlenecks.
- QR Code Generation and Mapping
Generating and linking unique QR codes to user accounts posed challenges in ensuring consistency, especially when data was being uploaded from multiple collection vehicles.
Solution:
We built a local buffer in the ESP32 for storing temporary data during collection. A robust synchronization algorithm ensured the data was uploaded accurately to the cloud once the vehicle was in range of a stable internet connection.
