Hemp Technology follow a zero-waste processing philosophy. The non-fibrous fraction of the hemp stem (approximately 75%) is made up of the shiv and smaller particles (or fines). The shiv is de-dusted, graded, bagged and palletised. The fines are further refined to remove the mineral component and either loaded into bulk containers or compressed into bio-logs.
Hemp Shiv

Hemp shiv is an absorbent, low-density cellulosic material that comes from the core of the hemp plant. Traditionally this material was used as a fuel. Today, Hemcore Horse Bedding is recognised as the leading products – prized for its cleanliness and high absorbency. The properties of the hemp shiv also make it uniquely compatible with lime for the production of Tradical Hemcrete®. Other uses of the shiv include low-density particleboard for numerous joinery applications and as an alternative to bark mulch.

Hemp shiv is usually supplied in 20 litre bags and stacked on pallets of 35 bales/pallet. 22 pallets/truck.
The cellulosic dust from the hemp plant is graded and further cleaned to remove the mineral component. Hemp fines find uses as a filler in plastics and in lime render, or compressed into logs for use as a fuel. Hemp fines can also be used as a soil improver.

Hemp Fiber
The hemp used in this research was grown in Australia.
The decorticated hemp was retted in a Thies Eco Bloc LFA
pressure dye kier together with NaOH solution. The retting
was carried out at 120 oC for 40 minutes and was followed
by a fresh bath rinse. The fiber was removed from the carrier
and squeezed using a Rapid Laboratory Pad Mangle at 3.0
bar pressure. The fiber was then dried using a Stray field 25T
RF Dryer. The dried fiber was then opened using a pinned
Fearnaught opener. The opened fiber was weighed under dry
conditions and cut into different lengths on a Fiber Trimmer
manually before mixing.
After retting and opening, hemp fiber width was measured
using an Optical Fiber Diameter Analyser (OFDA 100)
according to Australia Standard 4492.5-2000. Two thousand
fiber snippets were measured on each slide and the results of
five slides were recorded. The mean value of the five measurements
was taken as the fiber diameter (approximated and
referred to as fiber ‘width’ in this paperR
