In context: how this facility compares

At 220,000 t of pulp & paper, WPI Winstone Pulp International Ltd - Karioi Pulpmill Pulp Mill is around the median pulp & paper mill in New Zealand (249,480 t of pulp & paper). Subsector: pulp-and-paper. As pulp & paper mill, it requires high process heat (typically 150–250°C) for its core industrial operations, supplied by boilers, furnaces or direct combustion. Pulp and paper mills generate their own steam for the pulping process and paper dryers, running large-scale boiler systems where heat loss directly reduces efficiency.
