But there is another level, one which the NRMCA has
adopted. Sustainability applies not
just to the product, and the application of that product, but also to the
production. This shifts the focus
inward, with a spotlight on the enterprise.
And this bright light reveals very quickly whether sustainability was a
goodwill marketing effort, or is truly embedded in the company.
The NRMCA Sustainability Initiatives have challenged the
industry to meet some very aggressive goals by 2030: 30% reduction in embodied energy and carbon
footprint, 20% reduction in potable
water, 50% reduction in waste and a 400% increase in recycled content. They are tackling issues of source energy,
water re-use, and end-of life extension.
The target for plant design, production, maintenance and waste
management is aligned with zero waste discharge. Edward Mazria, CEO and founder of
Architecture 2030 notes: “This is precisely the kind of industry program that
can help the Building Sector meet its targets to lower GHG emissions. We’re
incredibly encouraged by the leadership NRMCA is providing to drive innovation
and reduce the carbon footprint of their industry.” Bravo
And now comes the difficult part and the greatest
opportunity. Concrete is an integral
part of most construction projects, especially commercial and industrial. There are about 2,500 ready mixed companies
that operate over 7,500 concrete plants in the US. This
is a workforce of local jobs, not just in the plants, but with a very visible
face at the job sites. The industry
relies on a veritable network of people, from the specifying engineers and
architects, to the finishers. In many
ways, concrete is the foundation of the construction industry. And herein lies the opportunity.
While many of the recommendations made by the NRMCA require
hard dollar investment, many more are a function of awareness and opportunity. For example, reducing the footprint of concrete
delivery is based on several choices:
truck size, delivery route, timing, minimizing truck idling, truck
maintenance. There are choices to be made about return concrete, truck
washing. It is also a result of decisions
of mix design (i.e. self-consolidating concrete for faster placement), and
agreements on truck route access. This
is a complex and interwoven combination of many decisions, by many people. It is
a unique opportunity to mobilize this army around a common mindset of sustainability,
embedded in the very fabric of every enterprise decision.
So I commend the NRMCA for adopting Architecture 2030, CEMEX
for their investment in a wind turbine,
applaud the continued research through MIT, and fully endorse
the concrete industry Joint Sustainability Initiative. And I also hope that our industry reaches
out to the key link in all of this – the very motive for sustainability - people.

I'm hopeful that the concrete industry takes this seriously. At this point, 2030 Challenge is little more than a marketing ploy. Most A/E firms do not consider the challenge when designing & it's more of an afterthought and tracking process, unfortunately. Here's hoping they're serious!
Sustainable concrete is a challenge and a step forward for the industry. Reducing fuel consumption with equipment that is modern and well maintained is important if the aggregates and construction industries are to reduce their impact on the environment. It would be great to see environmentally friendly success!
