Annual Environmental Report 2008 Cavanagh Foundry Ltd Section 2 – Report Structure 2.1 Licence Number - I.P.C Licence Registration Number P0479-02. 2.2 Name and Location of Site - Cavanagh Foundry Ltd, Birr, Co. Offaly. 2.3 Description of the activities on site:
The product is basically made of 2 no main component parts: - Ductile Iron Cover. - Fabricated Frame. (for alternatives)
Details of the manufacturing process are outlined below.
Raw Materials The furnace charge (raw material) at Cavanagh Foundry Ltd is characterised by the use of virgin or clean metals along with foundry returns. Ductile iron is manufactured from pig iron, scrap steel and foundry returns. Various ferro alloys such as silicon, magnesium and copper are added to treat the iron. Foundry returns are a mixture of the runners from castings and off spec products which are recycled. All foundry returns are self generated at the foundry. Scrap steel is made up principally of baled trimmings from new uncoated car panels and off-cuts from engineering shops. One tonne of molten iron is made of approximately 57% steel scrap, 21% pig iron, 16% returns and 6% ferro alloys. Ferro alloys are used to treat the iron and the addition rate is determined by analysis of each batch during production.
Melting of Raw Materials The current melting equipment consists of two 2-tonne capacity electric induction furnaces. The metal is heated to a temperature of approximately 1500°C. It is then poured from the furnace to a ladle which is used to transport the iron within the foundry. A series of metallurgical tests is carried out on the molten metal prior to pouring of the molten metal.

Annual Environmental Report 2008 Cavanagh Foundry Ltd _____________________________________________________________________
Electric melting furnaces represent the cleanest melting technology used in the foundry industry. The other main melting system used by foundries in Cupola melting which is associated with significantly greater environmental emissions.
Pouring A ladle is used to transfer molten metal from the furnace to the casting line. This ladle is moved by gantry crane and the molten metal is discharged into the mould. Magnesium is added directly to the ladle just before molten iron is poured from the furnace. The magnesium is a catalyst for a structural change in the molten metal from flake graphite to Sphereoidal graphite/ductile iron. Casting The molten metal is poured from the ladle into moulds which are made from sand, bentonite clay, coal dust and water. This moulding sand is termed “greensand”. The metal is poured from the ladle into the moulds which are moving on a casting trolley. The casting trolleys move the moulds from the mould preparation machine through the casting area where they are cast and back to a knockout area. During the transfer of the moulds from the casting area to the knockout area, the molten metal cools and a product is formed.
Knock-out The mould containing the casting is transferred to a knockout machine where the sand mould and product casting are pushed from the moulding flash. The used sand is collected on a rubber belt conveyor after falling through the knockout machine and conveyed back to the sand preparation plant for re-use. The now empty moulding flask is returned to the mould preparation area where it is again prepared for a further casting. The casting is moved to the finishing / assembly area where it is finished and assembled.
Painting All castings manufactured are coated with black bitumen primer.
Sand preparation and mould making Coal dust and clay are currently delivered to site in bags and stored in the courtyard. Sand is delivered in bulk.
Page 8 of 29
Annual Environmental Report 2008 Cavanagh Foundry Ltd _________________________________________________________________________
All the above materials are blended in a mixing mill which takes a proportion of each material from storage hoppers and mixes the material with greensand returned from the knock-out machine. Water is added to the mill and the blended material is conveyed by conveyor to the moulding machine where it is used to fill the moulding flasks in preparation for casting. The blend of moulding material is carefully monitored by carrying out a series of control tests in the laboratory.
Moulding
The mould flask, after the knock-out machine is moved into a moulding flask station prior to the mould preparation machine. Here the moulding flask is split into two parts. Each half is returned to the mould preparation machine where it is placed over an aluminium tooling pattern. Blended moulding sand is dropped into the moulding flask covering the tooling plate where it is compressed using air onto the pattern. Each moulding flask takes an impression of the tool and is then rotated where it can be inspected for quality. Cores may be added at this time. After exiting the mould preparation area the first half of the moulding flask is turned over and placed on top of the second flask. The completed mould is then placed in line onto the casting trolley at the start of the casting line where it awaits delivery of molten metal from the furnace.
FRAME MANUFACTURE Raw Materials The raw material consists of 46 X 46 x 3mm angle (min) iron to BS1449 and is attained from various suppliers. Certificates of conformity are requested from suppliers for the material.
Fabrication All frames are fabricated in jigs. The angle iron section is placed into the jig where it is clamped prior to welding.
Galvanising All fabricated frames are dispatched for galvanising where they are galvanised in accordance with the customer specification. Certificates of conformity to the galvanise specification are provided by the galvaniser.

________________________________________________________________________________ 3.2 Agency Monitoring and Enforcement
Euro Environmental Services carried out air monitoring on behalf of the Agency on 6th May 2008. Their analysis showed a breach in the emission limit value for total organic carbon at A2-3, as total organic carbon was detected at a concentration of 224.7mg/m3, against an emission limit value of 150 mg/m3. Independent monitoring of A2-3 conducted by Axis Environmental who are engaged by Cavanagh Foundry Ltd demonstrated compliant emission limit values at A2-3 on quarterly occasions during 2008. Cavanagh Foundry have outlined a commitment in various correspondence to Agency to convert to water based paint within nine months of dated of revised IPPC licence dated 6th November 2008.

Annual Environmental Report 2008 Cavanagh Foundry Ltd _____________________________________________________________________________________ 4.1 Introduction
Cavanagh Foundry Ltd Environmental Objectives and Targets have been determined by incorporating IPPC licence, ISO 14001 and business environmental initiative requirements. The company has been operating an Environmental Objective and Targets programme since 1999.
4.2 Schedule of Environmental Objectives and Targets
In accordance with the facilities IPPC licence and ISO 14001 requirements an Environmental Management Programme operates on an ongoing basis within the business. This EMP has been updated to reflect additional business environmental targets and objectives (ref section 5).
Table 8: Summary Table of Environmental Objectives and Targets for 2008 ENVIRONMENTAL OBJECTIVES ENVIRONMENTAL TARGETS
Construct ancillary building to make provision for internal water based painting system.

Annual Environmental Report 2008 Cavanagh Foundry Ltd ________________________________________________________________________________
4.3 Environmental Management Programme Report
4.3.1 Construct ancillary building to make provision for internal water based painting
system.
During the November - December of 2003 plans for an ancillary building which would incorporate internal painting facilities were established and were submitted to Birr Town Council along with an Environmental Impact Statement for planning permission in March 2004. Planning permission to construct ancillary building facility was obtained during September 2004. Tenders for construction were sought during November and are were reviewed by company environmental engineering consultants but project was postponed at the time. In November 2008 fresh tenders were sought from construction companies to build the ancillary building. Construction is underway at time of writing and it is expected that a water based painting system will be commissioned in new building by August 2009.
4.3.2 Construct and install new furnaces and associated building incorporating dry
bag filtration technology for furnace emissions. New furnaces were installed during August 2008. Furnace discharge dry bag filtration system is scheduled to be installed during the annual shutdown period in August 2009.
