Recycled glass is a good alternative to real sand and has been given the seal of approval by sand martin nesting at a quarry owned by
“Martins are renowned for nesting in stockpiles of natural sand but we’ve never before encountered them in our recycled products,” said Willington site manager Simon Bryant. “The martins like the sort of material which is soft enough to dig in but hard enough to remain stable. Although Envirosand satisfies these criteria we didn’t think it would be quite their cup of tea but it seems about 60 pairs decided to move in. It has been quite a surprise.”
Sand martins are a protected species so the Envirosand stockpile at Willington will be out of use until the chicks have hatched and the families have flown the nest.
