## Overview

This is a web platform for e-waste collection and recycling operations. Its central workflow assesses submitted products, values and reviews them, then coordinates pickup, hub delivery, inventory and transfers. Managers and supply-chain staff operate distinct stages; reporting, forecasting, sustainability and organizational administration are supporting capabilities documented in the README. Sampled source confirms assessment valuation, manager quotation handling, supply-chain pickup/stock routes, and report generation. Other documented modules are represented by their exact tree paths, but their internal wiring was not sampled.
