First reduce the waste at source, then recover the highest-temperature stream available, because a bigger temperature difference carries more usable energy. For ventilation and drying, air-to-air exchange is usually the cheapest first step; process exhaust at higher grade can feed absorption cooling or pre-heat combustion air. Financing shapes the decision as much as engineering: an energy-service contract or a shared-savings model can move a marginal project forward. Count carbon as well as fuel, since rising prices and reporting duties make avoided emissions valuable.
