Shanghai Guling Green Material Co., Ltd. offers wheat boards which are primarily made from agricultural straw. Sourcing waste straw keeps this material from being burned and lessens demand placed on already strapped wood industries. Adhesives used to bind straw are highly volatile and emit VOCs. Air quality should be measured and controlled within manufacturing facilities. Performance test reports are out of date, the most recent reports date back to 2006. When left to degrade in the biosphere, GuLing wheat board may harm waterways and aquatic life. If burned, dioxins may be released. Ideally, used boards should be reused.
