Carbon Footprint

---

As the management and reporting of carbon footprint has now become well

---

established we are currently preparing for what will be the next major step.

---

The “next big thing” after carbon footprint will be water footprint!

---

Our efforts to continually improve the carbon footprint of our products have proven to deliver excellent results. The new filler platform in Cornwall has a much lower carbon footprint than the old, although direct comparison is difficult due to the substantial changes in Cornwall. It is easier to look at the results achieved at IRCC.

 

Over the last few years we have introduced new product forms, such as TP (tube press) and GR (granulate) with much lower CO₂ effluents as a result. The trend for our average ex works carbon footprint across all kaolin production at IRCC from 2005 to 2009 shows the very significant level of improvement.

 

          

 

The advantages of our new low dusting and easy to disperse tube press and granulate product forms are obvious when measured at this “ex works” position. The higher moisture content of these product forms, compared to the spray dried product, does however mean that more water needs to be transported. It is therefore necessary to extend the analysis to include the logistics chain, bringing the products to our customers. Logistics plays a significant role in our carbon footprint as most of our customers tend to be some distance from our production site in Brazil. Through efficient use of large size ships and modern logistics hubs, such as our Eurohub in Antwerp, we are able to minimise this impact. The “delivered” carbon footprint of Capim™ DG, for instance, to port in Finland is reduced by 25% by going from spray dried to granulate product form.

 

The positive impact of our less energy intensive granulate product form is also reflected in other low energy product forms, i.e. tube press and slurry. It is clear, that for most customers in North America and Europe, these would be the lowest carbon footprint options.
