THE IMPORTANCE OF BUSINESS PARTNERSHIP IN SUSTAINABLE ENAMEL COST REDUCTION APPLICATION
Jack Nicholson – Escol Products

Abstract
The paper firstly addresses Sustainable Development issues and the responsibilities of companies to address economic growth, environmental protection, and social development within their local community. The importance of S.M.E’s (Small to Medium Companies) in addressing the broad issues of sustainable development is highlighted. The paper continues to show how industry can go beyond regulation compliance to yield real benefits in the efficient use of energy, materials, and water by dealing with the issues at the design and production stages. Today business sectors and governments are becoming more sensitive to social, environmental and ethical standards as consumer’s expectations for companies to act responsibly in these areas are demonstrated. It is also shown how companies can benefit by reducing waste. How vitreous enamel continues to be the best way of protecting steel is defined, and how best it satisfies sustainable development criteria. A typical impact assessment on a vitreous enamel user is shown. Reducing energy and waste is identified as a broad issue for enamellers. Escol’s approach to a cleaner way ahead is graphically demonstrated. The impact on the environment is established listing the improvements in recent years.
The Escol energy reduction programme is examined in detail:
Optimised auto programmes for gas/oxygen mix for all products.
Electronic skids and data loggers. Investment in flat fire burners. Improved yields, reduced gas/oxygen levels. Shorter batch times.
Automatic dampers on kiln exhausts – optimises energy utilisation.
Focus on right first time quality.) The waste minimisation programme and productivity improvement at Escol is graphically demonstrated.

Introduction
Waste minimisation

Reduction in fluorides and particulates.
How?
Use of heavy duty pan mixer with water additions for de-dusting
Installation of secondary abatement equipment. Re-use of spent CaF2 calcium fluoride.
Development of fluoride free frits.

Waste minimisation

Productivity improvements.
How?
Closed loop operation for raw materials
Batch weighing – de-dusting operation. Reduces batch melt fines. Re-smelting of dust hopper collections.
Frit re-melt programmes – programme for converting reject batches to good product.
Packaging recycling – drums and small IBC’s used.

The paper, up to new, focuses on the needs (i.e. The key issues for Sustainable Development are recognised) and identifies possible solutions by describing one company’s response to the internal challenge. The presentation now identifies the importance of successful business partnerships to the achievement of sustainable enamel cost reduction initiatives.

Successful business partners

Partnership with academia
Essential links with Universities and other Centres of Excellence

Partnership in specific development projects. Expert resources
South Bank University - Plasma spraying
University of Wolverhampton - Expert system for cast iron enamelling
Sunderland University - UK. Centre for sustainable development joint project scheme
General support, Analysis and trouble shooting
Enables focus on core issues internally

Partnership with customers
Enamel Cooker Market

Key elements are identified: Our business is dependent on our ability to understand the customers manufacturing requirements.
To design innovative products and process systems that complies with legislative and consumer standards at a competitive price.
As a result we operate in a very dynamic market situation as we strive to achieve manufacturing excellence by the use of simplified process solutions in order to reduce cost in all areas of the business.

Labour material energy overheads
Business success principles

Pre-requisites for sustainable relationship with enamel users

Market Total customer and consumer focus
Products and services Market led and customer driven
Manufacturing Quality key, ISO9002
Environmental registration, ISO14001
Sustainable developments

Operational efficiency determines level of profit when all of above elements are satisfied. The key
factors and agreed process success principles are cited. The establishing of customer and enamel
supplier agreed an objective is a primary consideration. These objectives are examined in critical
detail and include:

Nil pre-treatment
Enamels applied wet or dry to pressed components
Fully automated application systems
Material utilisation 100% - no waste
Total flexibility of colour change
Any colour any time/Zero WIP/ Batch size of one
All enamels supplied in ready-to-use form
All enamels fluorine free, environmentally friendly
All processes operate to zero defects
Single furnace requirement

Examples of successful projects are demonstrated. Methods for one coat enamelling pre-1995 is
compared to new innovative processes, such as two coat one fire white enamelling. An application
of enamel direct onto oiled pressings is a further typical example.
The benefits of a successful close working relationship are listed together with less tangible
advantages.

Benefits to all participants
Through close working relationship we are able to:
Develop a product in-line with market demands.
Focus clearly on process objectives
Ongoing direct dialogue shortens time frames
We are able to match resource to needs - Product
- Product support - COSHH
- Health and safety documentation
- Technical support
Fast response capability, ahead of competitor activity
Supply position – Endorses product and company

Less tangible benefits

People issues such as:
- Health & safety
- Employment law
- Quality management
Contact enables small company to maintain external contact on these topics.
As operators we all have legal obligations. The way we have to deal with our major customers provides a role model.
Exchange of ideas and people including works operatives.
Impact of environmental legislation
Emissions
- Land
- Air
- Water
Packing regulations

Business partnerships
Through product and process optimisation
Users will achieve:
High right first time
Low scrap
Less waste
Waste in future will have to be recyclable.
Waste will have to be recyclable?
Landfill directive: There are two very significant national waste policy principles that would encourage the development of sustainable solutions. The first is that treatment of waste close to source is actively encouraged through the proximity principle;
And the second is that there is still a need to find alternatives to landfill if Britain is to meet its obligations under the Landfill Directive

Sign up for alternative waste routes as soon as possible The UK will not have enough alternative waste management resources to deal with demand. “Prices are expected to dramatically increase”.

Strong case for Electrostatic powder - Totally recyclable
- Minimal waste
(hanger banger?)
Strong case for Ready-to-use wet - Minimise washings in mill room
- Reduces W I P
Current situation of In-house milling - Waste generated mill changeovers
- High inventory

leads to Increased disposal costs

Summary
Suppliers will have an increasing responsibility from cradle to grave. Suppliers to the UK market will have ownership and cost burden of customers enamel waste disposal.
In designing 100 recyclable vitreous enamel products and process systems we are protecting our industry for future generations.
