Hello. Since October 2007 I have worked for the [[Carbon Trust => http://www.carbontrust.co.uk]]. I'm in the Insights team, which means I work on publications that we produce on tricky climate change topics and help figure out how to improve what the Carbon Trust does. However, right now, I've been seconded to [[The Department for Energy and Climate Change => www.decc.gov.uk]] where I assist the department's chief scientist -- [[Professor David MacKay => http://www.inference.phy.cam.ac.uk/mackay/ ]].

h1. Remove toner: Reuse paper
…
_Thomas A. M. Counsell_
…
h2. Abstract
…
This thesis reports on experiments into whether abra-
sives, lasers or solvents can remove ordinary black toner-
print from ordinary white oﬃce paper in a way that leaves
the paper reusable. If it could be ‘un-printed’ then waste
oﬃce-paper could be reused immediately, without the need
for recycling.
…
Paper and board consumption causes approximately
1% of man-made climate change gas emissions. Estimates
in the ﬁrst chapter suggest that un-printing could reduce
emissions per tonne of oﬃce paper by up to 95% – greater
than the potential from incineration, localisation, annual
ﬁbre, ﬁbre recycling, un-printing or electronic paper.
…
There has been no academic work on un-printing, but
some relevant patents have been ﬁled. The second chapter
reviews these patents according to whether they remove,
obscure or de-colour the original print. It is not clear from
the patents whether toner-print can be removed by abra-
sives, lasers, or solvents without rendering the paper un-
usable. These three approaches are tested experimentally
and the results reported in chapters 3, 4 & 5.
…
Abrasives can remove toner-print with limited dam-
age to the underlying paper by operating in an adhesive
wear regime. This involves making ten passes with a ﬁne
P800 abrasive rubbing at high speeds (6 m/s) and low loads
(0.3 N). Longer wavelength lasers are able to remove the
toner-print and leave blank paper undamaged by operating
at 1 W and 10 kHz in the 1064 nm wavelength and scanning
across the surface eight times at 400 mm/s. Unfortunately
the paper beneath the print is yellowed during removal.
A 40:60 mixture chloroform and dimethylsulfoxide eﬀec-
tively dissolves toner without dissolving paper if agitated
with ultrasound for four minutes.
…
Chapter 6 outlines the research required to make the
approaches feasible replacements for conventional paper re-
cycling. The abrasive approach requires research into ex-
tending abrasive life. The laser approach requires research
into avoiding paper yellowing. The solvent approach re-
quires research into benign solvents and solvent recycling.
All three approaches would need to be tested on a wider
range of prints and papers.

…
The hypothesis of this project is that it may be possible to overcome these problems by using a different approach to removing ink that does not damage the paper and could be operated within and office. A machine suitable for an office of about 70 people would need to be able to clean the print off about 1.5 tonnes of paper a year, at a rate of one sheet every minute and a half, at a total cost of less than �1400 a year (implying a maximum capital cost of around �7000).
…
The work is funded by the Engineering and Physical Sciences Research Councill (EPSRC). Further information may be obtained from Tom Counsell (tamc2@cam.ac.uk) or in my publications.

h1. Remove toner: Reuse paper
…
_Thomas A. M. Counsell_
…
h2. Abstract
…
This thesis reports on experiments into whether abra-
sives, lasers or solvents can remove ordinary black toner-
print from ordinary white oﬃce paper in a way that leaves
the paper reusable. If it could be ‘un-printed’ then waste
oﬃce-paper could be reused immediately, without the need
for recycling.
…
Paper and board consumption causes approximately
1% of man-made climate change gas emissions. Estimates
in the ﬁrst chapter suggest that un-printing could reduce
emissions per tonne of oﬃce paper by up to 95% – greater
than the potential from incineration, localisation, annual
ﬁbre, ﬁbre recycling, un-printing or electronic paper.
…
There has been no academic work on un-printing, but
some relevant patents have been ﬁled. The second chapter
reviews these patents according to whether they remove,
obscure or de-colour the original print. It is not clear from
the patents whether toner-print can be removed by abra-
sives, lasers, or solvents without rendering the paper un-
usable. These three approaches are tested experimentally
and the results reported in chapters 3, 4 & 5.
…
Abrasives can remove toner-print with limited dam-
age to the underlying paper by operating in an adhesive
wear regime. This involves making ten passes with a ﬁne
P800 abrasive rubbing at high speeds (6 m/s) and low loads
(0.3 N). Longer wavelength lasers are able to remove the
toner-print and leave blank paper undamaged by operating
at 1 W and 10 kHz in the 1064 nm wavelength and scanning
across the surface eight times at 400 mm/s. Unfortunately
the paper beneath the print is yellowed during removal.
A 40:60 mixture chloroform and dimethylsulfoxide eﬀec-
tively dissolves toner without dissolving paper if agitated
with ultrasound for four minutes.
…
Chapter 6 outlines the research required to make the
approaches feasible replacements for conventional paper re-
cycling. The abrasive approach requires research into ex-
tending abrasive life. The laser approach requires research
into avoiding paper yellowing. The solvent approach re-
quires research into benign solvents and solvent recycling.
All three approaches would need to be tested on a wider
range of prints and papers.

The hypothesis of this project is that it may be possible to overcome these problems by using a different approach to removing ink that does not damage the paper and could be operated within and office. A machine suitable for an office of about 70 people would need to be able to clean the print off about 1.5 tonnes of paper a year, at a rate of one sheet every minute and a half, at a total cost of less than �1400 a year (implying a maximum capital cost of around �7000).
…
The work is funded by the Engineering and Physical Sciences Research Councill (EPSRC). Further information may be obtained from Tom Counsell (tamc2@cam.ac.uk) or in my publications.

Hello. I work for the [[Carbon Trust => http://www.carbontrust.co.uk]]. I've recently finished a PhD at [[Clare College => www.clare.cam.ac.uk ]], [[ Cambridge University => www.cam.ac.uk ]]. My research was with the [[Production Processes Group => http://www.ifm.eng.cam.ac.uk/pp/ ]] of the [[ Manufacturing Division => www.ifm.eng.cam.ac.uk ]] of the [[ Engineering Department => www.eng.cam.ac.uk ]]. My supervisor was [[Julian Allwood => http://www.ifm.eng.cam.ac.uk/people/jma42/ ]]. I was also the teaching assistant on the [[Manufacturing Engineering Tripos => http://www.ifm.eng.cam.ac.uk/met ]] course.
