Clinical Waste

    A new concept for Clinical Waste

    The effects of the removal of Crown Immunity and tighter standards for the
    incineration of clinical waste have resulted in huge changes in the way Health
    Trusts manage clinical waste. The Health and Safety Executive recommends
    thermal treatment for the disposal of high risk clinical waste. Unfortunately,
    the extra cost of pollution abatement required by progressive pollution
    controls has made on-site incineration difficult to achieve at an affordable cost.

    Compact Power has developed an advanced thermal conversion technology that
    provides a solution to these problems.

    This technology is ideally suited to meet the needs of Health Trusts and other
    clinical facilities within a Trust’s operational area. The benefits of immediate
    on-site disposal are achieved at the lowest cost, ensuring best value.
    Compact Power offer a build/own/operate service to NHS clients, and has the
    necessary expertise to structure projects under PFI. In many situations existing
    incineration or energy management centres can accommodate a Compact Power
    system, thus minimising infrastructure costs.

    Environmental Performance

    The environmental performance of the plant is substantially within the highest
    environmental standards anywhere in the world. As a leading edge environmental
    technology, operators can be confident that they will meet domestic standards for
    emissions for generations. Compact Power technology effectively minimises the
    impact of changes in environmental regulation to the benefit of our clients and

    NHS Solutions

    Compact Power has developed a new advanced thermal conversion technology
    for a wide range of clinical wastes using the processes of pyrolysis, gasification
    and high temperature oxidation. The plant is designed as a closed system in
    which all clinical waste materials are converted into simple gases and used to
    fuel a conventional steam power cycle. Facilities are designed to meet the
    highest environmental standards optimising energy recovery.

    Environmental Benefits

    • Low visual impact
    • Reduced traffic movement
    • No visible emissions
    • No noise
    • No smell
    • Emission levels significantly better than the latest EC Directive 2000/76/EC.

    Costs and Benefits

    The cost of disposal using Compact Power technology will be project specific, but a
    disposal cost of less than £250 a tonne is typical. When savings on transport costs
    are taken into account this represents a major cost reduction for many hospitals.


    • On-site secure solution
    • Safe and sure disposal route
    • Waste can be neutralised instantly
    • Designed to meet your needs
    • PFI funding available
    • Affordable disposal costs
    • Supplies usable heat and power

    Plant Description and Technology

    A Compact Power plant is dedicated to the safe destruction of clinical and
    pharmaceutical wastes. The capacity of the Facility is 6,000 tpa of solid waste
    with an average cv of 15Mj/kg (typical of hospital waste). The waste is reduced
    to 10% by weight and the resulting residues are accepted at ordinary landfill sites.
    Power production is from a steam cycle generating 330 kW(e) and 2.5MW(t).

    The plant is located within a purpose built building of low cost modular construction
    occupying a plot area of 90 sq metres. The roof height is 12m with a stack height
    of 1m above the eves, complying with the Environment Agencies requirement for
    this inherently clean technology.

    A Compact Power facility includes the following components:

    Waste handling and feed system

    The waste feed system is entirely enclosed. The waste-handling hall provides a
    secure area for short-term storage of waste and is designed to ensure a safe
    waste-handling regime. The waste is fed into the pyrolyser through feed hoppers
    that contain sufficient waste to keep the plant operational for up to 6 hours.

    Pyrolyser with twin chambers

    Materials are heated in the absence of oxygen to 800°c. Hydrocarbons are converted
    to simple gases leaving a residue of carbon char and inert grits. Each chamber can
    process up to 400 Kg of waste an hour.


    The carbon residues are then totally reacted out in the gasification phase with air
    and steam in the classic “water gas” reaction to produce hydrogen and carbon

    Thermal oxidiser

    Gases are reacted at high temperature, 1250°C for more than 2 seconds to ensure
    the destruction of any organic pollutants, particulates and dioxin precursors.

    Steam boiler

    Exhaust gases are passed through a steam boiler delivering heat and power,
    both of which may be used in the hospital. The steam is available for space and
    water heating and sterilization systems.

    Power generation

    The power system is based on a steam turbine driving an electricity generator.
    The power output is sufficient to generate the facility’s full requirements and
    still have power for export.

    No other process offers longer residence times at higher temperatures

    Compact Power Holdings plc AGM – Media Release – 30xi06Compact Power Holdings plc, the the AIM listed waste and biomass to energy company, held its Annual General Meeting in Bristol today. All resolutions put to shareholders were duly passed. Following completion of the formal business of the meeting, the Chairman, Nic Cooper, made the following statement: ‘Trading at the existing Avonmouth plant continues to improve with unaudited revenues for the six months to 30 September 2006 up 28 per cent on the same period last year due to higher volumes and gate fees. PDF

    Compact Power wins €1.64 million European contract. – Press ReleaseBristol 29 November 2006 Compact Power Holdings plc (‘Compact Power’), the AIM listed waste and biomass to energy company, is pleased to announce that it has been awarded a €1.64 million contract by Italcementi S.p.A. of Bergamo, Italy. The contract is to design, supply and install a Compact Power pyrolysis and gasification plant in Italcementi’s cement plant at Salerno in Southern Italy. The plant will produce a fuel gas generated from waste material which will be fed into the cement plant, replacing fossil fuels normally used in the process. PDF
