    Chemical Agent Reduces Xerox Printers Energy Use
    Xerox’s
    E-Agent – or embrittling agent – is a chemical ingredient that is
    claimed to reduce the amount of energy needed by certain Xerox printer
    toners by up to 22 per cent.Xerox’s E-Agent – or embrittling agent – is
    a chemical ingredient that is claimed to reduce the amount of energy
    needed by certain Xerox printer toners by up to 22 per cent. As a
    result, Xerox believes it is on the way to saving more than 30 million
    kilowatt hours of electricity by 2008 – enough power to light more than
    24,000 households for a year – and making strides toward its goal to
    cut global greenhouse gas emissions. John R Laing, senior vice
    president for Xerox Supplies Delivery Unit, said: ‘The manufacturing of
    supplies, especially toner manufacturing, is amongst the most
    energy-intensive activities within Xerox.With continuing innovations
    like E-Agent, we’re helping Xerox not only reduce costs but also
    contribute to a cleaner environment.’ Xerox said it is the inventor and
    world’s largest manufacturer of toner, producing it at eight locations
    worldwide.Toner is the ‘dry ink’ powder fused on paper to make laser
    prints and copies.In the conventional toner manufacturing process,
    large particles of plastics, colourants and other additives are
    mechanically pulverised in to small, relatively uniform toner
    particles.It takes about 50 of these toner particles to print a full
    stop on a page.According to Xerox, the grinding process is the most
    energy-intensive step, consuming up to 40 per cent of the total energy
    used for making toner.The grinding happens when toner particles are
    blown against each other at high speeds inside a chamber, and the
    collisions cause the particles to split apart.Xerox engineers knew that
    if the toner particles were easier to grind then the whole process
    would be more energy efficient.They discovered that by adding the
    embrittling agent to the toner recipe, particles would be more likely
    to shatter upon contact and reach the desired particle size more
    quickly.Depending on the product family, E-Agent makes the grinding
    rate up to twice as fast, it is claimed.The patented E-Agent process
    has been successfully implemented in toner for some Xerox products -
    such as the Xerox Docuprint and Docutech families of digital presses
    and printers – and is in the process of being tested for others.The
    company said by 2008, the energy savings associated with Xerox’s use of
    E-Agent is expected to avoid over 18,000 metric tonnes of carbon
    dioxide emissions – the equivalent of saving the annual emissions from
    over 2,500 cars.’We believe this ‘secret agent’ will be one of the
    success stories that helps Xerox achieve its greenhouse gas reduction
    goals,’ Laing said.Xerox has pledged to cut greenhouse gas emissions -
    the compounds in the atmosphere thought to trigger global climate
    change – from its worldwide operations by 10 per cent over a 10-year
    period.Xerox’s emissions result from using fossil fuels and buying
    electricity for power.To meet its target, Xerox is working to improve
    energy efficiency by 30 per cent compared to 2002 levels, throughout
    its global operations.Xerox’s pledge is consistent with its
    long-standing commitment to the protection of the environment and the
    health and safety of its employees, customers and neighbours.The
    company has received environmental awards worldwide, and it said it has
    pioneered conservation and protective environmental policies well in
    advance of governmental regulations.In addition to developments such as
    E-Agent, Xerox said it continues to develop more energy-efficient
    processes, products and technologies to help both the company and its
    customers meet their environmental objectives.
