Sustainability Calculations

Material Sustainability

Coin Compartment: Cardboard or reused plastic — recyclable and low-impact.

Note Compartment: Transparent acrylic or cardboard — durable and reusable.

Conveyor Belt: Rubber or repurposed belt — can use recycled rubber.

Main Body: MDF board or reused plastic — sustainable and easy to shape.

3D Printed Parts: PLA plastic — biodegradable and eco-friendly.

Energy Consumption Estimate

Component	Voltage	Current	Usage/Day	Energy Use/Day
Conveyor DC Motor	6V	500mA	10 mins	~0.05 Ah
Servo Motor (Sorting)	6V	300mA	5 mins	~0.025 Ah
Arduino Uno	5V	50mA	24 hrs standby	~1.2 Ah
Color Sensor	5V	20mA	Only when active	~0.005 Ah

Total Daily Consumption: ~1.3 Ah Power Backup Option: 5V 5000mAh power bank (lasts ~4 days)

Waste Reduction & Lifecycle

Most materials are reusable/recyclable

Estimated lifespan of components: 3–5 years

Minimal e-waste with responsible disposal
