Take-Make-Dispose – that’s long since been the model for heavy industries over the decades. It makes us all look bad and puts a target on us when it comes to environmental fallout. Air emissions and wastewater management are valid concerns – it is, after all, the focus of Motus Group. However, considering the ideas behind a circular economy, are there ways to close the loop in heavy industry?
Closing the Loop: The New Ideal
The circular economy challenges the traditional linear model by promoting closed-loop material flows. The waste usually created at the end of the product cycle are instead treated as a valuable resource that can be reintroduced into the system (yours, or others). Your favorite brewery likely partners with a farm somewhere that happily takes the spent grain from the brewing process to use as cattle feed. Less waste, less need to harvest new, raw materials.
The question is: how do we take this idea from the brewery floor to your specific production environment?
Call it “industrial symbiosis” – collaboration between several industries to exchange their byproducts as resources. Cement plants might use the heat generated from the nearby steel mill as an energy source – reducing their need to burn fuels. Non-potable water runoff from one factory can be used to cool another.
And, at its most basic, all emissions can be filtered and treated before returning them to the system they were drawn from.
Resource Efficiency: Doing More with Less
Resource efficiency lies at the heart of the circular economy. Efficient resource use means a reduced environmental impact. This includes:
- Minimizing raw material consumption: Implementing lean manufacturing practices, optimizing product design, and using recycled or alternative materials can reduce the need for virgin resources, lowering emissions associated with extraction, and processing.
- Optimizing energy use: Implementing energy-efficient technologies, utilizing renewable energy sources, and recovering waste heat can significantly reduce energy consumption.
- Extending product life cycles: Designing products for durability, repair-ability, and re-usability can prolong their lifespan, reducing the need for replacements and minimizing waste generation.
Yes, as much as we love sourcing spare parts and repairs for our customers, we always ensure you have the durable components to keep things running.
Waste Valorization: Turning Waste into Value
Waste valorization is the process of transforming waste into valuable products or energy.
- Advanced wastewater treatment technologies can recover valuable resources like water and nutrients, reducing freshwater consumption and minimizing discharges. Treated wastewater can be reused for industrial processes, irrigation, or even potable water production.
- Waste-to-energy: Converting industrial waste into energy through technologies like anaerobic digestion or gasification can reduce reliance on fossil fuels and lower greenhouse gas emissions.
- Byproduct synergy: Identifying opportunities to utilize industrial byproducts as raw materials for other industries can create new revenue streams and reduce waste disposal. For instance, slag from steel production can be used in cement manufacturing.
Benefits Beyond Emissions Reduction
Embracing circular economy principles offers a multitude of benefits beyond emissions reduction:
- Enhanced competitiveness: Reduced resource consumption and waste disposal costs can improve profitability.
- Innovation and new markets: Developing new technologies and processes for waste valorization can create new business opportunities and stimulate economic growth.
- Improved brand reputation: Demonstrating a commitment to sustainability can enhance brand image and attract environmentally conscious customers and investors.
From a high-level view, nothing about the circular economy should be surprising. At its most basic, you are finding ways to squeeze more value from resources you have already spent money to retain. Your accountants will love it. From the public perspective, the idea of “less waste” from an industrial site of any kind is always seen as a good thing. Additionally, when there is less competition for raw materials, there is more emphasis on finding ways to add value elsewhere in your system.
Circular approaches are a foundational idea to how we approach every project we work on. We’d love to see what we can do for your system. Give us a shout when it’s time for an update, retrofit, or a totally new install.
