Norman Jennings Australian Patent Application 593391 Filed 3 October 1986
Fertilizer from dried chicken manure developed by a NSW chicken farmer &
used worldwide.
Dynamic Lifter, the brainchild of Norman Jennings, was tested with help from
the NSW Department of Agriculture and came on the market in the late 1970s.
The product involves a method of making fertiliser from chicken manure using
two Australian technologies, a drinking system for the chickens which keeps
the manure dry, and a method of compressing the waste into pellets. The initial
patent application for the manure (35064/70) lapsed but a later one for a dripless
water trough was successful (AU 593391). Another for the sludge handling process
lapsed recently. Dynamic Lifter also has trade mark protection for some of their
products.
Dynamic Lifter is still run by the Jennings family and is manufactured overseas
under licence.
