Smart Material Choices
ACE has always been at the forefront of innovation, supplying the water industry with high quality solutions creating a low carbon footprint. In addition, we have focussed on sourcing materials with a low carbon footprint. Most notably for example, we were the first to introduce water flow control products manufactured out of HDPE and stainless steel to the UK industry, where traditionally, cast iron was used.
Implementing newer innovations brings down the TOTEX costs, especially when comparing the extended durability of the products and the low maintenance requirements closely linked to our material choices and design.
For example, cast iron flap valves require regular greasing whereas our HDPE flap valves and Wastop range do not. Corrosion is common in cast iron flap valves whereas this is rarely a problem for our WaStops and HDPE flap valves. This corrosion is also the root cause of “stuck” hinges as regularly seen with cast iron varieties.
HDPE Product Range
All our HDPE is virgin HDPE as unfortunately we cannot use recycled HDPE as the material properties are not as stable (it’s very hard to get a consistent quality from recycled, thus yield strengths etc vary too much for our requirements) but this has an upside when you look at the table in terms of CO2.
An easy example is our 500mm flap which weighs 13kg. 1 tonne of HDPE creates 0.8kg CO2 thus 0.8kg divided by 1000kg * 13kg = 10g of CO2
A 500mm Cast Iron valve typically weighs 64kg and grey cast iron produces 1.26kg of Carbon per tonne so 1.26kg/1000kg * 64kg = 80g of CO2
Thus, typically our flap valves as a product produce 8 x less CO2 than old-fashioned Cast-Iron valves – Furthermore, they are quicker to install, frequently don’t need lifting equipment where cast will, and don’t require grout which is also bad for CO2.
