IS the circular economy just a fashion with too many people jumping on the bandwagon without any real understanding of the inherent or underlying realities? Some people would have us believe so. But that would be to take a glass half-empty point of view when the glass is in fact half-full.
Waste is a big problem. Driven by modern consumerism, not only are landfill sites overflowing, spawning the illegal fly tippers and cowboy organisations trying to exploit the situation, but valuable resources are also being depleted.
Warnings are increasing about shortages of lack of raw materials with the world quickly running out of what is easily available. Accessing reserves is getting harder, more expensive and more environmentally destructive. While fly tippers are a local problem, illegal sand mining is the third-biggest crime globally.
It is not surprising that there are ever louder calls for a structured and integrated approach to waste management. For those looking for grand plans to solve the world's grand challenges, it is easy to miss what is happening at ground level and see that the building blocks for change are being put in place.
Every year, the Scottish construction industry consumes on average 29 million tonnes of aggregates. The industry accounts for 50 per cent of natural resource consumption, contributes to more than 50 per cent of our country’s waste and generates 40 per cent of its carbon emissions.
It’s clear that we need the means to provide better access to energy-efficient treatment plants that recycle and recover waste for reuse. Yet still, approximately one million tonnes of waste soil and rubble finds its way to Scottish landfill, while only 54% of construction projects have access to a sustainable resource management service.
What if this could change?
Construction waste consists of untapped valuable resources such as sand, stones, soil and clay that can be processed and resold back into the industry without affecting the environment. Working with our clients, over the past four years, we alone have diverted almost 810,000 tonnes of waste from landfill and replaced more than 660,000 tonnes of virgin aggregates with recycled aggregates in the local construction industry.
Our approach to the circular economy is to use it as a framework in all we do, from the fuel that drives our trucks and the logistics of moving waste, through to the recycling of the water that washes the waste through our plant.
Encouragingly, more and more companies in Scotland are thinking the same way. While popular schemes to reduce plastic and increase household waste recycling are highly visible to most people, other less-publicised but nonetheless significant innovations are happening across the business landscape that are making companies put circular first.
Granted, not everyone is onboard and we need to see more companies embrace the challenge of the circular economy. Whatever your view, however, the urgency remains the same. We need to change habits, as we need to change business practice. The more optimistic of us see that the tools are within our grasp.

Why are you making commenting on The Herald only available to subscribers?
It should have been a safe space for informed debate, somewhere for readers to discuss issues around the biggest stories of the day, but all too often the below the line comments on most websites have become bogged down by off-topic discussions and abuse.
heraldscotland.com is tackling this problem by allowing only subscribers to comment.
We are doing this to improve the experience for our loyal readers and we believe it will reduce the ability of trolls and troublemakers, who occasionally find their way onto our site, to abuse our journalists and readers. We also hope it will help the comments section fulfil its promise as a part of Scotland's conversation with itself.
We are lucky at The Herald. We are read by an informed, educated readership who can add their knowledge and insights to our stories.
That is invaluable.
We are making the subscriber-only change to support our valued readers, who tell us they don't want the site cluttered up with irrelevant comments, untruths and abuse.
In the past, the journalist’s job was to collect and distribute information to the audience. Technology means that readers can shape a discussion. We look forward to hearing from you on heraldscotland.com
