Conifer hedge standing volume to chip volume

[Ty Korrigan]

I wasn't bored, just my usual boring self, so I began taking a note of standing conifer hedge volumes before chipping.

This is really due to a recent regulation in France that requires the m3 of waste to be mentioned on quotes as part of a drive to screw down fly tipping.

So I found myself measuring conifer hedges.

I have found the volume is reduced between 8-10 fold with chipping.

Does this match others experience or am I well out?

   Yawn....

Heard years ago(don’t remember where)

8 to 1 volume of branches to volume of woodchip .

tight hedge like that would be similar, I would think.

I love your empirical approaches to work. Very useful. Also reminds me of the bit in DS9 where the Cardassians' record keeping is compared to the Nazis'.

I’m not convinced on 8-10 fold Stuart.

Hardwood crown, definitely, but a dense Leylandii has caught the most experienced of us out more than once with its lack of reduction.

I think you need to poke your head through the green and work out a 're-cut' factor. Sometimes the inside is quite open, sometimes it's a mass of branches and old footballs.

 

Then the answer is probably 4 to 10 depending on factor.

I know that is English, just not a dialect I am familiar with.

I would say, Leylandii, cough me many times, unpredictable really, plus minus 2 m3, on expected 6 m3, around that. Dense stuff I count 5 fold.

We took out a conifer hedge this week, one we have managed for ten years with trimming, so it was straight sided and flat topped, ie a bit easier to visualise volume reduction. Measuring accurately (26L x 2.5W x 3H) the volume of the hedge was 195 cu metres, but we need to allow for it having the trunks visible at the bottom. It was a dense hedge with no gaps. Let's say the volume of "air space" the hedge took up was 180 cu metres, or even take it down to a speculative 150 cu metres.

Our chip box capacity is 7.5 - 8 cu metres, when absolutely full. We got everything in with one and a half/two thirds loads, including room for rakes, all the sweeping and any timber that was not chipped.

So on this job we can safely say the volume reduction was at least 10 fold, and in fact probably a bit more.

Deep Space 9, Star Trek spin off, Cardassians=alien humanoid race.

Alien humanoid race is a good description of the cardassians
