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.

Operational Efficiency Initiatives

When was the last time you checked your technology spending against your IT infrastructure’s contribution to the bottom line?

Chances are, what’s happening underneath all those automated processes, expensive hardware, and fancy graphical user interfaces is not doing your bottom line any good.

If you don’t keep a watchful eye, your IT operations can easily nurture a lot of wastage and unnecessary costs. Underutilised servers, duplicate processes, poorly managed bandwidths, and too much complexity are among the common culprits.

For minor problems, we can eliminate wastage by setting up some technology enhancements, instilling best practices, and performing a few tweaks. However, if you’re not adequately trained on how to go about with it, your band-aid solutions can add more complexity to the mix.

Of course, there will always come a time when you will have to spend on new technologies to maintain the overall efficiency of your IT infrastructure. Whether you intend to purchase new hardware or software applications or build an entirely new infrastructure, the sheer cost of such undertakings warrants seeking expert advice.

Failure to do so can result in fragmented resources lacking in cohesiveness, which don’t contribute to efficiency at all.

Our solutions for improving operational efficiencies cover the entire spectrum: from planning what to buy, optimising what you’ve already bought, to making your team comfortable with them all. Please find time to view our solutions below and uncover ways to drive those profits up even as you work within your budget.

How Energy Conservation saved Fambeau River Paper

Rising energy costs caught this Wisconsin paper mill napping, and it soon shut down because it was unable to innovate. Someone else bought it and turned it around by measuring, modifying, monitoring and listening to people.

The Fambeau River Paper Mill in Prince County, Wisconsin USA employed 13% of the city?s residents until rising energy costs shut it down in 2006. Critics wrote it off as an energy dinosaur unable to adapt. But that was before another company bought it out and resuscitated it as a fleet-footed winner.

Its collapse was a long time coming and almost inevitable. Wisconsin electricity prices had grown a third since 1997, the machinery was antiquated and the dependence on fossil power absolute. So what did the new owners change, and is there anything we can learn from this?

The key to understanding what suddenly went right was the new owners? ability to listen. They requested a government Energy Assessment that suggested a number of small step changes that took them where they needed to go in terms of energy saving. These included enhancements in steam systems and fuel switch modifications. However they needed more than that.

The second game changer was tracking down key members of the old workforce and listening to them too. This combination enabled them to finally hire back 92% of the original labour force under the same terms and conditions – and still make a profit (the other 8% had moved on elsewhere or retired). The combined energy savings produced a payback plan of 5.25 years. Three years into the project their capital investment of $15 million had already clawed back the following electricity savings.

  • Evaporator Temperature Control $2,245,000
  • Hot Water Heat Recovery $2,105,000
  • Paper Machine Devronisers $1,400,000
  • Increased Boiler Output $1,134,000
  • Paper Machine Modifications; $761,000
  • Motive Air Dryer $610,000
  • Accumulator Savings $448,000
  • Densified Fuels Plant $356,000

In terms of carbon dioxide produced, the Fambeau River Paper Mill?s contribution dropped from 1 ton to 600 pounds.

How well do you know where your company?s energy spend is concentrated, and how this compares with your industry average; could you be doing better if you innovated, and by how much? Get these questions answered by asking ecoVaro how easy it could be to get on top of your carbon metrics. This could cost you a phone call and a payback on it so rapid it’s not worth stopping to calculate.

Is the GDPR Good or Bad News for Business

The European Union?s General Data Protection Act (GDPR) is a new data authority coming into force on 25 May 2018. It replaces the current Data Protection Directive 95/46/EC, while extending the remit to include the export of personal data outside the EU. It aims to give EU citizens and residents living there more control over their personal information. It also hopes to make regulatory compliance simpler for participating businesses.

The Broad Implications for Business
The GDPR puts another layer of accountability on businesses falling within its remit. It requires them to implement ?comprehensive but proportionate governance measures? including recording how they make decisions. The long-term goal is to reduce privacy infringements. In the short run, businesses without good governance may find themselves writing new policies and procedures.

Article 5 of the European Union?s General Data Protection Act lays down the following guidelines for managing personal data. This shall be ?
? Processed transparently, fairly, and lawfully
? Acquired for specific, legitimate purposes only
? Adequate, relevant and limited to essentials
? Not used for any other, incompatible purpose
? However it may be archived in the public interest
? Kept up to date with all inaccuracies corrected
? Ring-fenced when the information becomes irrelevant
? Adequately protected against unauthorised access
? Stored in a way that prevents accidental loss
Furthermore, affected businesses shall appoint a ?controller responsible for, and able to demonstrate, compliance with the principles.?

Implementing Accountability and Governance
The UK Information Commissioner?s Office has issued guidelines regarding provisions to assure governance and accountability. These are along the lines of the ?don’t tell me, show me? management approach the office has generally been following. In summary form, a business, and its controller must:
? Implement measures that assist it to ensure demonstrated compliance
? Maintain suitable, relevant records of personal data processing activities
? Appoint a dedicated data protection officer if scale makes this appropriate
? Implement technologies that ensure data protection by design
? Conduct data protection assessments and respond to results timeously

Implementing the General Data Protection Act in Ireland
The Irish Data Protection Commissioner has decided it is unnecessary to incorporate the GDPR into Irish law, since EU regulations have direct effect. The office of the Commissioner is working in tandem with data practitioners, and industry and professional bodies to raise awareness in business through 2017. It has produced a document detailing what it considers the essentials for business compliance. Briefly, these pre-requisites are:
? Ensure awareness among key personnel, and make sure they incorporate the GDPR into their planning
? Conduct an early assessment of quality management gaps, and budget for additional resources needed
? Do an audit of personal data held, to determine the origin, the necessity to hold it, and with whom shared
? Inform internal and external stakeholders of the current status, and your future plans to implement the GDPR
? Examine current procedures in the light of the new directive. Could you ?survive? a challenge from a data subject?
? Determine how you will process requests for access to the data in the future from within and outside your organization
? Assess how you currently obtain customer consent to store their data. Is this “freely given, specific, informed and unambiguous”?
? Find how you handle information from underage people. Do you have systems to verify ages and obtain guardian consent?
? Implement procedures to detect, investigate, and report data breaches to the Data Protection Commissioner within 72 hours
? Implement a culture of always assessing the effect on individual privacy before starting new initiatives

So Is the GDPR Good or Bad for Business
The GDPR should be good news for business customers. Their personal data will be more secure, and they should see their rate of spam marketing come down. The GDPR is also good news for businesses currently investing resources to protect their clients? interests. It could however, be bad news for businesses that have not been focussing on these matters. They may have a high mountain to climb to come in line with the GDPR.
