As climate change accelerates and governments around the world grow more serious about reducing greenhouse gas (GHG) emissions, manufacturers are realizing that esoteric sustainability goals in annual reports will no longer suffice. Conceptually, sustainable manufacturing is not complicated. Manufacturers can make their factories greener in numerous ways: reducing energy use through more efficient processes; minimizing GHG emissions by replacing traditional energy sources with renewables; improving uptime and production efficiency via digitalization and lean manufacturing processes; and, when all else fails, implementing carbon capture techniques to sequester or repurpose carbon emissions.
All these technologies and methodologies exist today-but the industrial world remains far from achieving truly sustainable manufacturing. The costs and complexity involved in upgrading 20th century facilities remain significant barriers to broader deployment of sustainability solutions in manufacturing, but increasingly, government mandates and end-user demand are driving executives in manufacturing verticals to acknowledge the writing on the wall.
This Guidehouse Insights report analyzes major trends in sustainable manufacturing and forecasts projected investment in four key technology areas that will be core to rendering industrial processes more sustainable: digitalization and industrial IoT (IIoT) technologies; increased renewables capacity through on-premises facilities; increased renewables capacity via power purchase agreements (PPAs); and carbon capture, utilization, and sequestration techniques. The report provides an overview of circular economy and recycling methodologies and describes numerous lean manufacturing principles. Finally, it projects global investments in core sustainable manufacturing technology segments by region and technology from 2024 through 2033.
