How Alcoa Canned the Cost of Recycling

Alcoa is one of the world?s largest aluminium smelting and casting multinationals, and involves itself in everything from tin cans, to jet engines to single-forged hulls for combat vehicles. Energy costs represent 26% of the company?s total refining costs, while electricity contributes 27% of primary production outlays. Its Barberton Ohio plant shaved 30% off both energy use and energy cost, after a capital outlay of just $21 million, which for it, is a drop in the bucket.

Aluminium smelting is so expensive that some critics describe the product as ?solid electricity?. In simple terms, the method used is electrolysis whereby current passes through the raw material in order to decompose it into its component chemicals. The cryolite electrolyte heats up to 1,000 degrees C (1,832 degrees F) and converts the aluminium ions into molten metal. This sinks to the bottom of the vat and is collected through a drain. Then they cast it into crude billets plugs, which when cooled can be re-smelted and turned into useful products.

The Alcoa Barberton factory manufactures cast aluminium wheels across approximately 50,000 square feet (4,645 square meters) of plant. It had been sending its scrap to a sister company 800 miles away; who processed it into aluminium billets – before sending them back for Barberton to turn into even more wheels. By building its own recycling plant 60 miles away that was 30% more efficient, the plant halved its energy costs: 50% of this was through process engineering, while the balance came from transportation.

The transport saving followed naturally. The recycling savings came from a state-of-the-art plant that slashed energy costs and reduced greenhouse gas emissions. Interestingly enough, processing recycled aluminium uses just 5% of energy needed to process virgin bauxite ore. Finally, aluminium wheels are 45% lighter than steel, resulting in an energy saving for Alcoa Barberton?s customers too.

The changes helped raise employee awareness of the need to innovate in smaller things too, like scheduling production to increase energy efficiency and making sure to gather every ounce of scrap. The strategic change created 30 new positions and helped secure 350 existing jobs.

The direction that Barberton took in terms of scrap metal recycling was as simple as it was effective. The decision process was equally straightforward. First, measure your energy consumption at each part of the process, then define the alternatives, forecast the benefits, confirm and implement. Of course, you also need to be able to visualise what becomes possible when you break with tradition.

Be pound poor and become Penny rich

Energy management is and should be perceived as a long-term investment by organisations. Having said this, the need for all organisations to implement energy management strategies now cannot be overstated as these strategies will save their costs of running the business in future.

Many organisations may shy off from implementing energy efficiency measures in place opting to save the associated costs or to use the cash for other projects that may be perceived as high priority in the short run. This is most likely to occur when cost cutting is a priority. Long-term planning is however critical for energy efficiency programs. Taking steps to improve building management and energy efficiency will and does pay dividends in the near-term and may be a competitive tool in the long-term.

Be energy smart
All energy management projects begin with being energy smart which calls for the understanding of energy usage. Use of Smart Meters that give real time readings of energy usage, can dramatically help businesses understand the benefit which energy management brings to the organisation.

Smart meters also cut the amount of time businesses spend on administration by allowing them to pay accurate bills, based on accurate readings. Some suppliers also support businesses to identify areas of energy wastage/inefficiency and help setting targets for energy reduction that guide behavioural change with regard to energy in the organisation.

Use of technologies that record the energy usage at the water or electricity meters putting data into a system where the users can graph it has made it easy to compare energy consumption in various departments, sites or buildings. Appropriate measures can then be implemented to improve the efficiency.

Partnerships between businesses and energy suppliers
Since the long-term benefits of reduced energy consumption is beneficial to both suppliers and consumers; the responsibility of managing energy consumption is being taken by both. Businesses should work with the suppliers on cost reduction strategies through identifying areas where energy is being wasted and advising businesses on how to save energy. Of key importance when choosing an energy supplier therefore is their depth of understanding of a business’ energy management needs.

Capitalise on government incentives
Businesses should always explore varied financing mechanisms for their energy efficiency programs e.g. government schemes generating electricity and selling it to the grid.

Are Target Operating Models strategic compasses?

The short answer is they usually are, because every organisation needs a road-map of where they are going. Target operating models can be complex documents with illustrative details including project management structures, special tools, implementation procedures and management metrics. They can also be simple statements, as for example Winston Churchill?s promise that ?we shall fight them on the beaches, on the landing grounds and in the fields? which gave Britain the strategic direction it needed.

Many initiatives unfortunately fail because managers are ?too busy? to bottom on what their target operating model should say, or simply don’t believe in paperwork. As a result, promising initiatives may blunder off course or die a slow death without them really noticing. We cannot manage what we cannot measure, which is where the management metrics fit in. One of my favourite quotes is ?if you don’t know where you are going any road will get you there? which is what the Cheshire Cat said to Alice in Wonderland when she got lost.

The author blundered through life without a plan because there was no one else with his particular brand of imagination. The current business climate is different because everybody is trying to ramp up, and investors want to know exactly what is going to happen to their money and by when. Hence a target operating model can be indispensable throughout a change or product cycle.

The benefits of having a measurable operations / technology plan can produce powerfully tangible results if the organisation follows through on it. Built-in metrics with milestones are powerful tool for management, and, when they map through to the company financial plan almost irreplaceable as cash-flow forecasters.

Other benefits may include:

  • Shorter times to market and greater agility when launching new ideas
  • Reduced investor risk through a predictable process that’s readily monitored
  • A stable operating environment where there is consensus on direction
  • Greater likelihood of delivering on time and leading to repeat orders
  • A more cost-effective process, with less risk of loss of quality and money

Although it dates back a few years the Wills UK and Ireland Retail model still provides an excellent benchmark of a target operating plan that worked. The strategic goals were exceptionally clear, and they brought in a proven project manager to help them drive the program forward.

Energy Audit – clearly clear?

An energy audit is an examination of an energy system to ensure that energy is being used efficiently. It is the inspection, survey and analysis of energy flows for energy conservation in a building. Energy audits can be conducted by building managers who examine the energy account of an energy system, checks the way energy is used in its various components, checks for areas of inefficiency or where less energy can be used, and identifies the means for improvement.

An energy audit is often used to identify cost effective ways to improve the comfort and efficiency of buildings. In addition, homes/ enterprises may qualify for energy efficiency grants from central government. Energy audits seek to prioritise the energy uses from the greatest to least cost effective opportunities for energy savings.

An energy audit is an effective energy management tool. By identifying and implementing improvements as identified, savings can be achieved not only on energy bills, but also equipment will be able to attain a longer life under efficient operation. All these mean actual dollar savings.

An energy audit has to be conducted by a competent person with adequate technical knowledge on building services installations, after which he/she comes up with a report recommending plans on the Energy Management Opportunities (EMO) for energy saving.

An energy audit culminates to a written report. This could show energy use for a given time period (for example a year) and the impact of any suggested improvements per year. Energy audit reports are then used to identify cost effective ways to improve the comfort and efficiency of buildings. The energy audit report therefore gives management an understanding of the energy consumption scenario and energy saving plans formulation.
Energy audit reports should always translate into action. No matter how well articulated, the energy management objectives are afterall, an energy audit (EMOs), all the effort will be futile if no action is taken. The link between the audit and action is the audit report. It is therefore important for the audit reports to be understandable for all the target audiences/ readers, all of whom may have diverse needs, hence the reason why they should be clear, concise and comprehensible.

What are the do?s and don’ts when writing energy audit reports?

Avoid technical jargon as much as possible; present information graphically; use different graphics such as pie charts, data tables. Schematics of equipment layouts and digital photos tend to make EMO reports less dry. Some of the energy audit software?s come in handy in the generation of such graphs and charts.
The climax of it all is the recommendations, which should be made very fascinating.
