Introduction

In today’s energy-conscious world, businesses and industries are constantly seeking ways to improve efficiency and reduce environmental impact. One of the most promising technologies gaining traction is waste heat recovery (WHR). This process captures excess heat generated in industrial operations and reuses it for power generation or heating, reducing overall energy consumption. In this blog, we explore the Waste Heat Recovery market, its key drivers, applications, challenges, and growth outlook.

Market Overview

The global waste heat recovery market has experienced steady growth due to rising energy costs, stringent environmental regulations, and increasing awareness about energy efficiency. As of 2023, the market was valued at
