  • Concrete corrosion and fatbergs plague sewage systems around the world, leading to costly and disruptive maintenance.
  • Fatbergs are gross globs of congealed mass clogging sewers with fat, grease, oil and non-biodegradable junk like wet wipes and nappies, some growing to be 200 metres long and weighing tonnes.
  • The environmental cost is greater — ordinary Portland cement accounts for about 5% of the world’s greenhouse gas emissions.
