Rhino Ark is re-launching its plastic fence post initiative in partnership with Finlays, the horticultural export company.
Rhino Ark pioneered the conversion of plastic waste from flower farms in 2000 after it purchased a 20-year-old agronometer and extruder to make 4-inch posts from a well-established plastics company in England.
Naivasha flower farmer, the late Mike Higgins of Kijabe Ltd put the machine to work on a voluntary basis as an added contribution to Rhino Ark’s conservation efforts.
As a result of the success with the first machine in 2003, the same English company, KweenBee, donated a second larger unit that extrudes 6 inch posts.
Both units have now been installed at Finlays’ Kingfisher Farm in Naivasha and are producing posts to be used in Mt Kenya and Mau Eburu. Under an agreement with Homegrown, the posts are being provided at cost to Rhino Ark.
Plastic posts have proved their resilience and have an indefinite life span as compared with wooden posts that do eventually disintegrate.
Plastic posts have other benefits – they are cheaper than wood, do not need pricey plastic insulators as current flow using U nails creates no electricity transfer in plastic. The posts bend back upright once impacted by an angry elephant or other threat. Wooden posts snap and have to be replaced.
Since 2000 when plastic posts were introduced into the fence build process the completed Aberdare fence – nearly 400 kms long – contains one in five posts made from plastic waste. The entire fence contains 100,000 posts of which 20,000 were of plastic.
“We have set a challenge to the flower industry to create value out of waste”, said Colin Church, Chairman of the Rhino Ark Management Committee. “Rhino Ark is a living demonstration that where there are alternatives to wood from trees, they can be used effectively”, he added.
