Recycle Week – reasons to use lime mortar

The 21st – 27th September 2020 is ‘Recycle Week’ which is a celebration of recycling. This year, the theme thanks the nation for continuing to recycle despite the challenges that COVID-19 has presented, under the banner ‘Together – We Recycle’.

Using lime mortars in new building projects as a replacement for cement mortars could make recycling materials easier because…


  • Old lime mortar can be easily crushed and recycled for use as aggregate in new lime mortars.
  • Bricks and stone bedded in lime mortar can easily be dismantled and re-cycled for new building projects when the building reaches the end of its life.
  • Ridge tiles bedded in lime mortar on roofs can easily be removed without damage during re-roofing, and re-cycled for use on the same roof.
  • Old lime mortar can be crushed and re-cycled as a soil conditioner to balance the pH of soils.
