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.

What Sub-Metering did for Nissan in Tennessee

When Nissan built its motor manufacturing plant in Smyrna 30 years ago, the 5.9 million square-foot factory employing over 8,000 people was state of art. After the 2005 hurricane season sky-rocketed energy prices, the energy team looked beyond efficient lighting at the more important aspect of utility usage in the plant itself. Let’s examine how they went about sub-metering and what it gained for them.

The Nissan energy team faced three challenges as they began their study. They had a rudimentary high-level data collection system (NEMAC) that was so primitive they had to transfer the data to spread-sheets to analyse it. To compound this, the engineering staff were focused on the priority of getting cars faster through the line. Finally, they faced the daunting task of making modifications to reticulation systems without affecting manufacturing throughput. But where to start?

The energy team chose the route of collaboration with assembly and maintenance people as they began the initial phase of tracking down existing meters and detecting gaps. They installed most additional equipment during normal service outages. Exceptions were treated as minor jobs to be done when convenient. Their next step was to connect the additional meters to their ageing NEMAC, and learn how to use it properly for the first time.

Although this was a cranky solution, it had the advantage of not calling for additional funding which would have caused delays. However operations personnel were concerned that energy-saving shutdowns between shifts and over weekends could cause false starts. ?We’ve already squeezed the lemon dry,? they seemed to say. ?What makes you think there?s more to come??

The energy team had a lucky break when they stumbled into an opportunity to prove their point early into implementation. They spotted a four-hourly power consumption spike they knew was worth examining. They traced this to an air dryer that was set to cyclical operation because it lacked a dew-point sensor. The company recovered the $1,500 this cost to fix, in an amazing 6 weeks.

Suitably encouraged and now supported by the operating and maintenance departments, the Smyrna energy team expanded their project to empower operating staff to adjust production schedules to optimise energy use, and maintenance staff to detect machines that were running without output value. The ongoing savings are significant and levels of shop floor staff motivation are higher.

Let’s leave the final word to the energy team facilitator who says, ?The only disadvantage of sub-metering is that now we can’t imagine doing without it.?

Vendor Selection

When shopping for an IT solution for your enterprise, there are two things you should scrutinise: the product (or service) itself and its vendor. Many times, companies overlook the importance of the latter, giving the reason that “it’s only the product we need”.

Wrong.

What about after-sales technical support and training? Ok, so you have an in-house team with the required competency for that IT solution in question… not that I believe it’s reasonable basis to pass up on the expertise that the vendor can provide. How about upgrades, patches, and documentation?

Still unperturbed? Here’s one factor that you may not have started to consider – What happens to your product if the vendor goes bankrupt or gets swallowed by a merger and acquisition? Surely, you no longer believe this is far from possible, do you?

But how are you supposed to know the financial stability of each vendor or whether it is an acquisition target? Well, you can either conduct your own research or you can leave that up to us. Part of our job includes not only establishing linkages in the industry but also being in-the-know on such relevant information.

Evaluation of Business Needs

You can’t separate vendor selection from the process of choosing the desired IT tool. That’s why our vendor selection services starts by defining exactly what your business needs are.

Once we’ve pinned down your needs, we can then narrow down the list of possible IT solutions. Only then can we proceed with the main vendor selection process.

Have you ever been caught in a situation wherein you thought you knew what you wanted, only to end up realising it’s not what you were looking for after all? We’re here to make sure you don’t get caught in that kind of situation when choosing an enterprise-class IT solution.

With the TCO (total cost of ownership) of such solutions typically running up to hundreds of thousands of euros, you can’t afford to arrive at what you really want by way of trial and error.

These are the things you stand to benefit the moment we start working with you:

  • Thorough assessment of your IT needs. We’ll consult the people in your organisation who’ll be affected the most in order to obtain a clear picture of what your specific needs really are. Most IT solution purchases are made with very little consultation that, after installation, many of the end users don’t benefit at all.
  • Minimal interruption during assessment. As with all our other services, we see to it that the interruptions we make are absolutely necessary. So the moment we start with our work, you can still continue with yours.
  • Insightful suggestions of the required IT solution. You still know your business better. So even after we’ve gone through the assessment and given our recommendations, the decision as to what IT tool should be pursued will still be up to you. The difference now is, you’ll be making a decision based on expertly gathered information put forward in an insightful proposal.

Request and Evaluation of Vendor Proposals

With so many IT solutions companies mushrooming, it is becoming more difficult to keep track of them, their specialities, strengths, and weaknesses.

Companies selling best-of-breed products may be relatively easy to spot. But there are also other attributes that are equally important but not as well publicised. For instance, which companies offer better quality management philosophies? Which companies have strategic visions running parallel to yours? Which of them possess implementation capabilities that can cater to your rapidly growing IT requirements?

Vendors who answer positively to these queries need to be given the appropriate importance in the selection process. We see to it that these and other relevant attributes are factored into our scorecards and evaluation processes.

These are the things you can look forward to when you grant us the opportunity to serve you.

  • Experience is a vital item in our vendor selection criteria. Our vast knowledge of the reliable players in the industry will lead you to experienced vendors who can hit the ground running from day one and continue with the same vigour onward.
  • We can help you draw positive response for each of your Request For Proposals (RFPs) or Request For Information (RFIs). Did you expect these vendors to be enthusiastic in sending out proposals each time you asked them to? Think again. You’ll have to persuade them first of your sincerity to become a potential customer. With our help, your RFPs will make preferred vendors see “opportunity” written all over.
  • No need to go “Eany, meeny, miny, moe”. Deciding which vendors should move up in the selection process can take up a lot of time if you don’t know which criterion should be given more weight. Our scorecards are designed to collect the most relevant information and to generate results that will help you decide on these matters at a glance.

Interview, Negotiation, and Monitoring

As soon as you start getting positive response to your Request For Proposals, the interview process should be next. It’s at this point that vendors can present and highlight their strengths while we try to glean as much information of their true capabilities as well as their dedication to the project.

Some companies can provide proof-of-concepts and we may require them as part of the interview process. This will not only give us a better idea as with regards to their product’s capabilities, but also to their level of expertise on the solution in question.

  • We’ll help you set up the interview process and organise the evaluation committee. Members of the committee will typically include representatives from each department that will be affected by the new technology, which we would have already identified during our Evaluation of Business Needs.
  • Since our scorecards are designed to expedite the filtering and selection process, you may eventually be able to choose the finalists yourself. However, in the event that two or more vendors turn out evenly matched, we’ll help you identify the better company.
  • We’re very familiar with the price ranges of various IT solutions, including the effects on price of certain variables. As such, we can tell you whether a product’s price tag is justified or not.
  • Our exceptional familiarity on both the IT industry and the entire negotiation processes itself will give you the edge when it’s time for us to haggle for the best bang for the buck.
  • After the contract is awarded, we’ll even be on hand to monitor whether deliverables are handed over and milestones are achieved as promised.
2015 – What’s ahead for UK Business?

According to reports just in, the global environment industry is down. Less money is available for what some CEO?s still see as grudge expenditure, and many U.S. agencies are seeking soft budget cuts. The UK is proving to be an exception following the announcement of ESOS, and EcoVaro does not expect the May elections will have much impact in this regard.

ESOS calls for mandatory energy assessments in companies above a certain size, and requires specific proposals to cut consumption. There is no indication of compulsory follow-through, although it is clear the Environment Agency hopes rising electricity prices and the prospect of monetary savings will do the trick.

It is an open question whether the Tory government would have interfered with commerce to this extent, were it not for the European directive that enforced it. The overall goal is to cut EU energy consumption across the board by 20% by 2020. Energy consultants are rubbing their hands in glee. EcoVaro?s response is to provide cloud-based software.

We will be interested to see how many UK companies make the first deadline of 5 December 2015, in the light of reports that half the 9,000 firms affected appear not to even know that ESOS exists. Some will no doubt pay last-minute lip service. Those with an eye on their own sustainability will grasp the Energy Saving Opportunity Scheme with both hands.

The initial ESOS deadline was always going to be a challenge. Some big corporates have stolen a march albeit egged on by green stakeholders. The next challenge comes in June 2015 with the implementation of the European Union?s ?Waste Catalogue? of hazardous substances, and rules for their disposal. We hope a new ISO 14001 will arrive soon and pull the loose threads together.

The introduction of carbon trading late this year brings further opportunities to increase profits through wise stewardship. Auditable metrics are essential for this.
