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.

How to be cleaner and greener indoors

The supply of water on planet earth is finite hence the need to conserve this precious resource. Water is a utility that is often used in and outdoors and for that reason, water conservation activities should be undertaken everywhere.

Get greener everywhere
Water saving can be achieved through various ways. Of utmost importance, fixing leaks should be undertaken in all areas. Small household leaks can add up to gallons of water lost every day. It is therefore important to check all water system fixtures and ensure that there are no leakages.

Greener bathroom habits
Turning off taps- this should be practised in the bathroom especially while shaving and brushing teeth. One could also consider using showers instead of baths since showers use less water and get into the habit of taking shorter showers.

Clean and green dishes
The kitchen is one of the areas where a lot of water is used. Some of the ways through which water can be conserved in the kitchen are:

  • Use of basins when washing dishes by hand
  • Using a dishwasher – when using the dish washer, it is important to make sure it’s fully loaded. Scraping plates instead of rinsing before loading it into the dishwasher will also go a long way in the conservation of the valuable commodity called water

Green your laundry and earn green bucks
The other area where water saving can be made is the laundry room. Washing only full loads of laundry will ensure that your washing machine is running at full efficiency hence you will be able to maximise your washer for energy efficiency. Always ensure you use the appropriate water level or load size selection on the washing machine. All these will not only save water but energy too and since savings are earnings you can smile all the way to the bank where some green bucks will be credited to your account.

The Child at Work: Fun Team Builds with LEGO SERIOUS PLAY

There is a child just below the surface in all of us. When were kids, adults lopped off the sharp bits that intruded into their ?genteel? society. Schools, to their everlasting shame sanded away our unique free spirits, as they stuck us into uniforms and imposed a daily classroom discipline. We received badges and prizes if we obeyed, and strict sanctions when we did not. This produced a generation of middle-age managers who no longer know how to play.

Life can be so deadly serious ?

Things work pretty much the same in business. Life is deadly serious. If we want to keep our jobs, we must deliver on the bottom line in our departments. There is little time for fun outside the Christmas party, when we may, within the limits of decorum engage in activity for enjoyment and recreation, rather than a serious or practical purpose.

Team builds (and strategic planning sessions) can be deadly boring affairs that proceed down narrow funnels defined by human resource facilitators. No matter how hard HR they may try, the structural hierarchy will remain intact, unless they find a way to set it aside during the program. Injecting fun into the occasion liberates independent thought, and this is why.

? But not for a little child at play

Next time you dine out at a branded family restaurant, select a seat that allows you observe the kiddies? play zone. Notice how inventive children become, when the family hierarchy is not there to tell them what to do (although parents may try from the wrong side of the soundproof glass). The ?serious play? side of fun team-builds aims to liberate managers by releasing their child for the duration. Shall we dig a little deeper into this and discover the dynamics?

Many of us have less than perfect oral communication skills. This is one of the great impediments to modern business meetings. We may not have sufficient time to formulate our thoughts for them to remain relevant when we speak. When we express them, we sense the group?s impatience for us to hurry up, so other members can have their opportunity to contribute.

Sharing better thinking with LEGO? bricks

Most of us feel an urge to click the brightly coloured plastic bricks together that carpenter Ole Kirk Christiansen released into a war-weary world in 1949. The basic kit is a great leveller because the blocks are all the same, and the discriminators are the colours and the power of our imagination. Watching a free-form LEGO builder in action is equally fascinating, as we wonder ?what they will do next? and ?what is happening in their mind.?

Examples of LEGO Serious PLAY in action

Instead of asking team members to describe themselves in a minute, a LEGO? SERIOUS PLAY? facilitator may gather them around a table piled high with LEGO bricks instead, and ask them to each build a model of themselves. The atmosphere is informal with interaction and banter encouraged. It is still serious play though, as team members get to know each other, and their own personalities better

The system is equally effective in strategic sessions, where the facilitator provides specially selected building blocks for the team to experiment with as they learn to listen, and share. This enables them to deconstruct a problem into its component parts, and share solutions regardless of seniority, culture, and communication skills.

Creating problem- and solution-landscapes three dimensionally this way, enables open conversations that keep the focus on the problem. Participants at these team builds do not only reach effective consensus faster. They are also busy building better communication skills as they do.

The Better Way of Applying Benford’s Law for Fraud Detection

Applying Benford’s Law on large collections of data is an effective way of detecting fraud. In this article, we?ll introduce you to Benford’s Law, talk about how auditors are employing it in fraud detection, and introduce you to a more effective way of integrating it into an IT solution.

Benford’s Law in a nutshell

Benford’s Law states that certain data sets – including certain accounting numbers – exhibit a non-uniform distribution of first digits. Simply put, if you gather all the first digits (e.g. 8 is the first digit of ?814 and 1 is the first digit of ?1768) of all the numbers that make up one of these data sets, the smallest digits will appear more frequently than the larger ones.

That is, according to Benford’s Law,

1 should comprise roughly 30.1% of all first digits;
2 should be 17.6%;
3 should be 12.5%;
4 should be 9.7%, and so on.

Notice that the 1s (ones) occur far more frequently than the rest. Those who are not familiar with Benford’s Law tend to assume that all digits should be distributed uniformly. So when fraudulent individuals tinker with accounting data, they may end up putting in more 9s or 8s than there actually should be.

Once an accounting data set is found to show a large deviation from this distribution, then auditors move in to make a closer inspection.

Benford’s Law spreadsheets and templates

Because Benford’s Law has been proven to be effective in discovering unnaturally-behaving data sets (such as those manipulated by fraudsters), many auditors have created simple software solutions that apply this law. Most of these solutions, owing to the fact that a large majority of accounting departments use spreadsheets, come in the form of spreadsheet templates.

You can easily find free downloadable spreadsheet templates that apply Benford’s Law as well as simple How-To articles that can help you to implement the law on your own existing spreadsheets. Just Google “Benford’s law template” or “Benford’s law spreadsheet”.

I suggest you try out some of them yourself to get a feel on how they work.

The problem with Benford’s Law when used on spreadsheets

There’s actually another reason why I wanted you to try those spreadsheet templates and How-To’s yourself. I wanted you to see how susceptible these solutions are to trivial errors. Whenever you work on these spreadsheet templates – or your own spreadsheets for that matter – when implementing Benford’s Law, you can commit mistakes when copy-pasting values, specifying ranges, entering formulas, and so on.

Furthermore, some of the data might be located in different spreadsheets, which can likewise by found in different departments and have to be emailed for consolidation. The departments who own this data will have to extract the needed data from their own spreadsheets, transfer them to another spreadsheet, and send them to the person in-charge of consolidation.

These activities can introduce errors as well. That’s why we think that, while Benford’s Law can be an effective tool for detecting fraud, spreadsheet-based working environments can taint the entire fraud detection process.

There?s actually a better IT solution where you can use Benford’s Law.

Why a server-based solution works better

In order to apply Benford’s Law more effectively, you need to use it in an environment that implements better controls than what spreadsheets can offer. What we propose is a server-based system.

In a server-based system, your data is placed in a secure database. People who want to input data or access existing data will have to go through access controls such as login procedures. These systems also have features that log access history so that you can trace who accessed which and when.

If Benford’s Law is integrated into such a system, there would be no need for any error-prone copy-pasting activities because all the data is stored in one place. Thus, fraud detection initiatives can be much faster and more reliable.

You can get more information on this site regarding the disadvantages of spreadsheets. We can also tell you more about the advantages of server application solutions.
