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.

Monitoring Water Banks with Telemetrics

Longstanding droughts across South Australia are forcing farmers to rethink the moisture in the soil they once regarded as their inalienable right. Trend monitoring is an essential input to applying pesticides and fertilisers in balanced ratios. Soil moisture sensors are transmitting data to central points for onward processing on a cloud, and this is making a positive difference to agricultural output.

Peter Buss, co-founder of Sentek Technology calls ground moisture a water bank and manufactures ground sensors to interrogate it. His hometown of Adelaide is in one of the driest states in Australia. This makes monitoring soil water even more critical, if agriculture is to continue. Sentek has been helping farmers deliver optimum amounts of water since 1992.

The analogy of a water bank is interesting. Agriculturists must ?bank? water for less-than-rainy days instead of squeezing the last drop. They need a stream of online data and a safe place somewhere in the cloud to curate it. Sentek is in the lead in places as remote as Peru?s Atacamba desert and the mountains of Mongolia, where it supports sustainable floriculture, forestry, horticulture, pastures, row crops and viticulture through precise delivery of scarce water.

This relies on precision measurement using a variety of drill and drop probes with sensors fixed at 4? / 10cm increments along multiples of 12? / 30cm up to 4 times. These probe soil moisture, soil temperature and soil salinity, and are readily re-positioned to other locations as crops rotate.

Peter Buss is convinced that measurement is a means to the end and only the beginning. ?Too often, growers start watering when plants don’t really need it, wasting water, energy, and labour. By monitoring that need accurately, that water can be saved until later when the plant really needs it.? He goes on to add that the crop is the ultimate sensor, and that ?we should ask the plant what it needs?.

This takes the debate a stage further. Water wise farmers should plant water-wise crops, not try to close the stable door after the horse has bolted and dry years return. The South Australia government thinks the answer also lies in correct farm dam management. It wants farmers to build ones that allow sufficient water to bypass in order to sustain the natural environment too.

There is more to water management than squeezing the last drop. Soil moisture goes beyond measuring for profit. It is about farming sustainably using data from sensors to guide us. ecoVaro is ahead of the curve as we explore imaginative ways to exploit the data these provide for the common good of all.

What Heijunka is & How it Smooths Call Centre Production

The Japanese word Heijunka, pronounced hi-JUNE-kuh means ?levelling? in the sense of balancing workflows. It helps lean organizations shift priorities in the face of fluctuating customer demand. The goal is to have the entire operation working at the same pace throughout, by continuously adjusting the balance between predictability, flexibility, and stability to level out demand.

Henry Ford turned the American motor manufacturing industry upside down by mass-producing his iconic black motor cars on two separate production lines. In this photograph, body shells manufactured upstairs come down a ramp and drop onto a procession of cars almost ready to roll in 1913.

Smoothing Production in the Call Centre Industry

Call Centres work best in small teams, each with a supervisor to take over complex conversations. In the past, these tended to operate in silos with each group in semi-isolation representing a different set of clients. Calls came through to operators the instant the previous ones concluded. By the law of averages, inevitably one had more workload than the rest at a particular point in time as per this example.

Modern telecoms technology makes it possible to switch incoming lines to different call centre teams, provided these are multi-skilled. A central operator controls this manually by observing imbalanced workflows on a visual system called a Heijunka Box. The following example comes from a different industry, and highlights how eight teams share uneven demand for six products.

This departure from building handmade automobiles allowed Henry to move his workforce around to eliminate bottlenecks. For example, if rolls of seat leather arrived late he could send extra hands upstairs to speed up the work there, while simultaneously slowing chassis production. Ford had the further advantage of a virtual monopoly in the affordable car market. He made his cars at the rate that suited him best, with waiting lists extending for months.

A Modern, More Flexible Approach

Forces of open competition and the Six Sigma drive for as-close-to-zero defects dictates a more flexible approach, as embodied in this image published by the Six Sigma organisation. This represents an ideal state. In reality, one force usually has greater influence, for example decreasing stability enforces a more flexible approach.

Years ago, Japanese car manufacturer Toyota moved away from batching in favour of a more customer-centric approach, whereby buyers could customise orders from options held in stock for different variations of the same basic model. The most effective approach lies somewhere between Henry Ford?s inflexibility and Toyota?s openness, subject to the circumstances at the moment.

A Worked Factory Example

The following diagram suggests a practical Heijunka application in a factory producing three colours of identical hats. There are two machines for each option, one or both of which may be running. In the event of a large order for say blue hats, the company has the option of shifting some blue raw material to the red and green lines so to have the entire operation working at a similar rate.

Predictability, Flexibility, and Stability at Call Centre Service

The rate of incoming calls is a moving average characterised by spikes in demand. Since the caller has no knowledge whether high activity advisories are genuine, it is important to service them as quickly as possible. Lean process engineering provides technology to facilitate flexibility. Depending on individual circumstances, each call centre may have its own definition of what constitutes an acceptably stable situation.

Strategy and Portfolio Management

 

A well planned strategy is the necessary bridge between brilliant leadership and excellent execution. Without it, your entire organisation cannot hope to respond quickly and effectively to challenges and changes within the landscape on which it operates.

Strategic planning involves identifying objectives, understanding what resources are needed to attain them, and then allocating the resources to the appropriate units to ensure they are used optimally towards the achievement of desired objectives. Among the end results which can be reflected by your team members are:

  1. Deeper understanding of the competitive environment;
  2. Snappy execution of plans;
  3. Faster, more aligned actions; and
  4. More intelligent and apt responses against strategic moves of the competition.

We understand the need to institute strategic management in such a way that your organisation can easily adapt to unforeseen developments. As such, all our solutions are formulated to make your organisation not only well-guided but also as dynamic as possible.

Strategy Formulation

Before you can proceed to map out any strategy for your company, you’ll have to study your company’s current environment. This will help you determine what courses of action should be taken to be able to navigate through such environment on your way to the end goal.

If you’re not a full time strategist, such a task can either be very daunting or deceivingly easy… the former can prevent your team from getting started, while the latter can lead your team astray.

Ideally, strategy formulation should be carried out as quickly and as efficiently as possible so you can move on to implementation before the competition can react. Our methods can enable your leaders to hit the ground running each time they set out on a strategic plan.

How?

  • We can assist in accurately applying strategic tools like SWOT and Gap analysis, then help integrate the results into an effective strategic plan.
  • We’ll train your team how to carry out effective research techniques so that the information they gather will really be what we need. This is because the tools mentioned earlier can only work effectively if the inputs were picked intelligently. Of course, if you want the entire process expedited, we can also conduct the research ourselves.
  • We’ll establish best practices for top-down, bottom-up, and collaborative strategic management processes. We’ll even show you how to organise and hold meetings where team members are constantly engaged and in-sync, so action plans can be developed and relayed fast.
  • We’ll see to it that strategies for all functional departments (such as IT management, supply-chain, HR, marketing, and legal) are in line with your business strategies, which should in, turn be aligned with your overall corporate strategy.

Strategy Evaluation

Your strategies have to be periodically assessed if you want to determine whether they are attuned to variations affecting your organisation. These changes may include new technologies, emerging competitors, new opportunities, as well as unexpected developments in the economic environment and political climate.

While no time limit is imposed for the build-up of resources vital to the attainment of a specific objective, the window of opportunity can shut on you before you can start amassing such resources. Given this possibility, it is important for your strategies to undergo evaluation processes that will determine whether you should pursue them or not.

Using only the most reliable evaluation techniques, we’ll help you establish whether:

  • Your strategies will place your company in a position that will give it competitive advantage or will erode whatever advantage the competition already has;
  • Your strategies are consistent with the landscape on which your company currently traverses;
  • They are realistic enough in relation to the resources you have on hand;
  • The associated risks have all been identified and the appropriate control measures have already been put in place;
  • The time frames for their full realisation are both realistic and acceptable.

Portfolio Management

In today’s highly competitive market, many of the more successful enterprises are driven by project-based systems.

Now, there’s always a tendency for project managers to become overenthusiastic and to come up with a number of projects that can’t be sustained by available resources. If your project-based company frequently runs out of resources, then either you just have too many projects running or too much is being allocated to a select few.

In both instances, the problem does not necessarily lie on the individual project managers themselves. Rather, what is needed is the ability to have full control over existing projects and investments.

Your leadership should be able to rank projects in terms of their impact to your organisation’s growth, positioning, and profitability. This will give you sufficient information when deciding which projects to pursue, prioritise, or shut down. These are the benefits you’ll gain from our services:

  • A vivid presentation of the big picture. Only when you can step back from all the detail and see the interplay of investments and resources will you be able to make wise decisions regarding how and where to position them.
  • The ability to distinguish between projects with the highest potentials and those that are outdated.
  • Access to expertise that will help you distribute your present IT infrastructure, human resources, financial resources, and facilities across running projects to obtain the biggest benefits for all stakeholders.
