Industrial Symbiosis Network (2D)

An eco-industrial park is more than a collection of factories on shared land — it works when one plant's waste becomes another's raw material. This simulator lays out a set of facilities on a 2D site map, each producing one byproduct and needing one or more others, and greedily builds a pipeline network between them under a distance and capacity budget, exactly the kind of matching problem real industrial-symbiosis planners (following the Kalundborg model) solve when siting a park. Adjust the number of facilities, the maximum economical pipeline reach, and each plant's connection capacity, and watch the diverted-waste and virgin-input-saved percentages — and the byproduct flow-share bar chart — respond as the network reconfigures. Drag the map to pan and scroll to zoom, just like exploring a real site plan.
