SHARING OPTIONS: CBH encourages local interaction and local communities were asked to put their art stamp on the large storage towers to help make them more interesting. When you pass through Western Australia (WA), big tower silos labelled CBH are a common sight. CBH stands for Co-operative Bulk Handling, which is a grain growers' co-operative that handles, markets and processes grain from across the wheat belt of WA. CBH was formed in April 1933, under the principle of one person, one vote, regardless of the amount of grain supplied and that principle still applies today. It has undergone many structural changes since its conception and it assembles most of its grain directly from the combines at harvest.
