Research shows that building supply chains in many countries could account for as much as 40% of the man made carbon emissions. Most building growth is taking place in Third World countries. Concrete is the most widely used building material. In many countries, as for example in Tanzania concrete blocks are the most widely used building material. Cement is the most expensive component and also has the highest carbon footprint. Earlier research indicates that there is a substantial improvement potential in reduced costs, improved customer value and reduced environmental impact in the building material supply network in Dar es Salaam Tanzania. Even if reasonably simple solutions with good payback for realising the potential exist, change is slow.


The purpose of this paper is to study how process and product innovations could be visualised with the purpose of driving change towards more sustainable block making processes and products.


Current processes and products are summarised and compared with benchmarks identified in literature and in practise. Drivers and barriers for change from current to benchmark performance are identified by field studies of block makers including participant observations and interviews. Additionally some performance testing is carried out. These results in combination with previous ones are then visualised using proposed process based sustainability indicators.

Main resultsResults confirm earlier findings. The identified technical causes are relatively easy to solve. The main barrier for change seems to be lack of drivers and habits preferring proven solutions. The detected potential could be realised in an “Private Public Partnership”.
