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.

Benefits of Energy Savings Opportunity Scheme (ESOS)

More than just building energy, improving skills and undertaking audits, Energy Savings Opportunity Scheme works beyond. ESOS adheres to policy coherence, provides information to raise awareness, facilitates energy efficiency market and encourages adoption of appropriate energy efficiency measures.

Generally, ESOS is great for energy professionals and businesses. And in the current situation of UK?s energy industry, this new scheme is a substantial help. The key is to know the benefits that ESOS provides, understand how it can affect you, learn how to maximise its potential and make a big difference. Here?s to explore the highlights of ESOS.

Who benefits from ESOS?

Energy Savings Opportunity Scheme covers non-SME enterprises which includes UK businesses having more than 250 employees; even those with employees fewer than 250 but have annual turnover of more than ?50m and balance sheet exceeding ?43m; or those professionals that belong to a large enterprise. This is in accordance with what Article 8 of the EU Derivative provides.

What are the benefits of ESOS?

ESOS provides opportunities to enhance an organisation’s energy efficiency strategy, of which the benefits include:

Economic Growth and Competitiveness

The implementation of energy efficient measures increases local employment in the labour markets. Consequently, this taps the labour potential and drives economic growth.? In a lower carbon economy, businesses need to develop green projects to maintain economic competitiveness as well. ESOS is strategic approach initiated by the UK government to push technological innovation and energy investments.

Cost Savings and Emission Reductions

ESOS is flexible in such a way that it combines energy policies and innovations tailored to every organisation’s need. The energy efficiency measures taken, resulting from the scheme, quickly cuts down both carbon emissions and energy bills at cheapest possible ways.

Managing Energy Demand

ESOS provides energy security to UK by reducing the energy consumption of enterprises. With this, the economy would be more efficient and less exposed to international energy market volatility. Also, this will lead to more savings from less future investment in energy infrastructure.

Getting your Management Performance Noticed

If you are an energy professional, you will benefit from ESOS by exploiting it ?to boost your charisma towards the company directors. You can show them how the scheme works and how it can save your company substantial costs. Managing energy with ESOS can help an organisation grow. Nevertheless, you are the key person designated to get the project done and achieve success.

How can ESOS make a difference?

More than anything else, ESOS can make a huge change. True to its name, it provides large enterprises the opportunity to manage energy wisely, reduce overhead costs and promote responsible corporate energy consumption.

The International Energy Agency said that investing in energy efficiency leads to growth, additional jobs, competent budgets on public spending and enhanced industry productivity. If you are an energy and environment professional or a non-SME business entity, you hold the impulse to act. Aside from all those excellent business benefits that you get to enjoy, you will be able to contribute a portion towards achieving UK?s national carbon target of 80% in CO2 by 2050.

Could Kanban Be?Best for Knowledge Workers?

Knowledge Workers include academics, accountants, architects, doctors, engineers, lawyers, software engineers, scientists and anybody else whose job it is to think for a living. They are usually independent-minded people who do not appreciate project managers dishing out detailed orders. Kanban project management resolves this by letting them choose the next task themselves.

The word ?Kanban? comes from a Japanese word meaning ?billboard? or ?signboard?. Before going into more detail how this works let’s first examine how Japanese beliefs of collaboration, communication, courage, focus on value, respect for people and a holistic approach to change fit into the picture.

The Four Spokes Leading to the Kanban Hub

  1. Visualise the Workflow ?You cannot improve what you cannot see. The first step involves team members reducing a project to individual stages and posting these on a noticeboard.
  2. Create Batches ? These stages are further reduced to individual tasks or batches that are achievable within a working day or shift. More is achievable when we do not have to pick up where we left off the previous day.
  3. Choose a Leader the Team Respects – Without leadership, a group of people produces chaotic results. To replace this with significant value they need a leader, and especially a leader they can willingly follow.
  4. Learn and Improve Constantly ? Kaizen or continuous improvement underpins the Japanese business model, and respects that achievement is a step along the road, and not fulfilment.

The Kanban Method in Practice

Every Kanban project begins with an existing process the participants accept will benefit from continuous change. These adjustments should be incremental, not radical step-changes to avoid disrupting the stakeholders and the process. The focus is on where the greatest benefits are possible.

Anybody in the team is free to pull any batch from the queue and work on it in the spirit of collaboration and cooperation. That they do so, should not make any waves in a culture of respect for people and a holistic approach to working together. All it needs is the courage to step out of line and dream what is possible.

The Kanban Project Method ? Conclusions and Thoughts

Every engine needs some sort of fuel to make it go. The Kanban project management method needs collaboration, communication, courage, focus on value, respect for people and a holistic approach to work. This runs counter to traditional western hierarchies and probably limits its usefulness in the West.

Saving Energy Step 5 – Bringing it together

We hope you have been enjoying our series of short posts regarding saving energy, so what we use we can sustain. We have tried to make a dry subject interesting. After you read this post please comment, and tell us how it went. We are in the environment together. As the man who wrote ?No Man is an Island? said, ?if a clod be washed away somewhere by the sea, Europe is the less? and Europe was his entire world.

The 4 Steps we wrote about previously have a multiplier effect when we harness them together

  1. Having a management system diffuses office politics and pins accountability in a way that not even a worm could wriggle
  2. This defines the boundaries for senior managers and empowers them to implement practical improvements with confidence
  3. The results feed back into lower energy bills: this convinces the organisation that more is possible
  4. This dream filters through all levels of the organisation, as a natural team forms to make work and home a better place.

None of this would be possible without measuring energy consumption throughout the process, converting this into meaningful analytics, and playing ?what-if? scenarios against each other to determine where to start.

The 5th Step to Energy Saving that brings the other four together can double the individual benefits as innovative power flows between them. The monetary savings are impressive and provide capital to go even further. Why not allow us to help you manage what we measure together.

ecoVaro turns your numbers into meaningful analytics, makes suggestions, and stays with you so we can quantify your savings as you make them. We should talk about this soon.
