Wallerscote Island storage and packing facility - the finished soda ash was transported over the River Weaver by conveyor belt to the silos, and then loaded onto boats or railway wagons for distribution.

This structure contained a series of towers in which ammonia was bubbled up through and absorbed into concentrated brine to create ammoniated brine. Carbon dioxide (produced in the kilns by heating of limestone) was then bubbled up through the ammoniated brine, which caused sodium bicarbonate to form.

Finishing plant - sodium bicarbonate (produced by the reaction of ammoniated brine and carbon dioxide) was sent to the finishing plant to be dried and calcined (heated) into soda ash.

Lime kilns - limestone (calcium carbonate) was burnt in the kilns to produce carbon dioxide which was bubbled up through ammoniated brine to create sodium bicarbonate. The burning of the limestone also produced lime (calcium oxide), which was used to recover the ammonia used in the process. Waste from the kilns was transported to Wallerscote lime beds by rail and pipeline for disposal.

Soda crystal plant - sodium carbonate solution was pumped into large pans and allowed to crystallise. The crystals took up to 2 weeks to form and were broken up by hand and transported to the crusher by a narrow gauge railway system, then packaged and sold as washing soda.
