Energy from WasteWhat about the leftovers?

• Opportunities for bottom ash recycling
• David York
• MD Ballast Phoenix Ltd

2

• BALLAST PHOENIX Ltd major shareholder is Feniks
  Recycling, a Dutch IBA processor since the early
  1980s
• Commenced first commercial operations in 1998.
• Six facilities currently operating.
• Over 3 million tonnes of IBA processed and sold.
• Over 35 plant years of experience.
• All products are sold NOT land filled.
• From early days BPL has continued to develop new
  markets for IBAA.

Company culture

• Key elements are
• Safe working
• Environment protection
• Providing a full and professional service to our
  customers
• A REAL BELIEF IN WHAT WE DO!

What do we do?

• Following the thermal treatment, the main residue
  is bottom ash a misleading term as much of it
  has not burnt, metals, glass, porcelain and the
  like are a large part of the material. We process
  this and
• Recover the ferrous metal
• Recover the non ferrous metals
• Create alternative aggregates for construction

6
An Aggregates business

• Whilst IBAA processing recovers all these
  resources, it is only successful if it produces
  GOOD QUALITY AGGREGATE.
• This means particle sizes up to 40mm of hard
  durable inert material such as glass porcelain,
  brick, stone, with some slag, clinker and ash
• There are many uses for well processed IBA

IBA aggregates

• What can IBAA be used for?
• Many applications

IBA has pozzolanic properties and this property
is beneficial. A stockpile about 18 months old
being ripped to separate particles. The
temperature inside the stockpile was 55c.

Local Government SustainableProcurement Strategy
Nov. 2007

• The residue from MSW and CI waste, after energy
  recovery can now be processed for re-use (IBAA)
  Sustainable
• IBAA gives local authorities value for money
  without compromising quality
• Compliant with Procuring the Future 2006
• BREEAM sustainable construction (BRE)
• SLAM requires 20 recycled for all new build
• (Single Living Accommodation Modernisation
  Programme) Government led initiative

19

• IBAA is part of a sustainable solution for MSW
  and CI waste
• IBAA will reduce the carbon footprint of any
  construction project where it is employed
• We have plants operating in London, Birmingham,
  Teesside, Essex, Kent and Sheffield

20
Carbon footprint

• IBAA has a very low carbon footprint. Carbon
  costs in production are low and the benefits
  high. BPL has consulted Carbon Trust and will
  seek accreditation.

IBAA Carbon Sequestration

• CO2 is absorbed from atmosphere
• Similar to concrete carbonation
• gt8 by weight of CO2 can be absorbed
• IBA Aggregates have a negative footprint

23
How do we make IBAA from IBA?

• Our sister company in Holland first started
  this kind of business in the early 80s. BPL
  started in the UK in 1998, using the Dutch
  process technique, but with UK applications.
  Since then the process has been extended such
  that a target of ZERO LANDFILL can be a reality.

Environmental Management

• The impending WRAP Quality Protocol is designed
  to give new users confidence in IBAA BPL has
  had its own scheme for many years. Site Specific
  Environmental Assessments are available to BPL
  customers free of charge
• BPL is accredited with BSI to BS EN 140012004
• The Environmental Liability Directive (ELD) came
  into force on 1st March 2009, outlining
  responsibilities!
• The Water Framework Directive is designed to
  ensure that groundwater and water courses are not
  polluted.

39
DUTY OF CARE Environment Protection Act 1990

• Applies to companies and individuals
• Primary and secondary aggregate producers
• BPL assess every site prior to supply
• IBAA leach test results normally around UK
  drinking water quality standard

Exploding concrete????

• An unfortunate incident took place in Aug 2009. I
  believe this is the subject of an ongoing HSE
  investigation. Gas was trapped beneath a
  footbridge, inside a building. Sparks created by
  work activity ignited the gas and two workers
  were unfortunately injured. Our HS data sheet
  states that when IBAA is used in foamed concrete,
  it should be handled and used in open spaces.
