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.

Total Quality Management

Total Quality Management (TQM) is another business management approach that focuses on the involvement of all members of the organisation to participate in improving processes, products, services, and the culture in which they work in. It is important that every team member realises how each individual and each activity affects, and in turn is affected by, others.

With the use of combined quality and management tools, TQM also aims to reduce losses brought about by wasteful practices, a common concern in most companies. Using the TQM strategy, business would also be able to identify the cause of a defect, thereby preventing it from entering the final product.

Deming’s 14 Points

At the core of the Total Quality Management concept and implementation is Deming’s 14 points, a set of guidelines on quality as conceptualised by W Edwards Deming, one of the pioneers of quality. Deming’s 14 points are as follows:

  1. Create constancy of purpose for improving products and services.
  2. Adopt the new philosophy.
  3. Cease dependence on inspection to achieve quality.
  4. End the practice of awarding business on price alone; instead, minimise total cost by working with a single supplier.
  5. Improve constantly and forever every process for planning, production and service.
  6. Institute training on the job.
  7. Adopt and institute leadership.
  8. Drive out fear.
  9. Break down barriers between staff areas.
  10. Eliminate slogans, exhortations and targets for the workforce.
  11. Eliminate numerical quotas for the workforce and numerical goals for management.
  12. Remove barriers that rob people of pride of workmanship, and eliminate the annual rating or merit system.
  13. Institute a vigorous program of education and self-improvement for everyone.
  14. Put everybody in the company to work accomplishing the transformation.

But if you were to reduce to bare bones the TQM philosophy from Deming’s 14 points, it would all come down to two simple goals:

  1. To make things right the first time; and
  2. To work for continuous improvement.

As with all other quality management process, the end goal is to be able to offer products and services that meet and even exceed customer’s expectations.

How Mid-South Metallurgical cut Energy Use by 22%

Mid-South in Murfreesboro, Tennessee operates a high-energy plant providing precision heat treatments for high-speed tools – and also metal annealing and straightening services. This was a great business to be in before the energy crisis struck. That was about the same time the 2009 recession arrived. In no time at all the market was down 30%.

Investors had a pile of capital sunk into Mid-South?s three facilities spread across 21,000 square feet (2,000 square meters) of enclosed space. Within them, a number of twenty-five horsepower compressors plus a variety of electric, vacuum and atmospheric furnaces pumped out heat 27/7, 52 weeks a year. After the company called in the U.S. Department of Energy for assistance, several possibilities presented.

Insulate the Barium Chloride Salt Baths

The barium chloride salt baths used in the heat treatment process and operating at 1600?F (870?C) were a natural choice, since they could not be cooled below 1200?F (650?C) when out of use without hardening the barium chloride and clogging up the system. The amount of energy taken to prevent this came down considerably after they covered and insulated them. The recurring annual electricity saving was $53,000.

Manage Electrical Demand & Power

The utility delivers 480 volts of power to the three plants that between them consume between 825- and 875-kilowatt hours depending on the season. Prior to the energy crisis Mid-South Metallurgical regarded this level of consumption as a given. Following on the Department of Energy survey the company replaced the laminar flow burner tips with cyclonic burner ones, and implemented a number of other modifications to enhance thermal efficiency further. The overall natural gas reduction was 20%.

Implement Large Scale Site Lighting Upgrade

The 24/7 nature of the business makes lighting costs a significant factor. Prior to the energy upgrade this came from 44 older-type 400-watt metal halide fixtures. By replacing these with 88 x 8-foot (2.5 meter) fluorescent fittings Mid-South lowered maintenance and operating costs by 52%

The Mid-South Metallurgical Trophy Cabinet

These three improvements cut energy use by 22%, reduced peak electrical demand by 21% and brought total energy costs down 18%. Mid-South continues to monitor energy consumption at each strategic point, as it continues to seek out even greater energy efficiency in conjunction with its people.

Fine-tuning your Operations and keeping our staff Happy with FieldElite

They are the engine that drives your operations, but are you really giving you value for your money? How much time is spent by your personnel on lengthy paperwork and record-keeping, as opposed to actually providing the service to your customers? Manual tasks create bottlenecks and slow your operations, which in turn affects service delivery and customer satisfaction. You want to reach more clients and boost your brand image, growing your market share and generating more revenue. Field Service Management (FSM) software comes in optimise the operations of your mobile workforce, cut down resource wastage, and enhance your productivity as a firm, by actually enabling your field staff to get more done, thus achieving their individual goals. In fact, according to a report published by Fortune Business Insights?, the global FSM market- which stood at $2.29 billion as recently as 2018, will have expanded to $7.27 billion by 2026. What does this mean for your employees, and how do they benefit from FieldElite?

  • Skipping the paperwork with end-to-end automation

Filing reports, keeping track of equipment used, working on the Excel sheets for multiple jobs on a daily basis, all through to the routing and billing- it can be a logistical nightmare. It’s not just about the hours spent poring through documents and typing away at calculators. Manual work exposes you to the risks of human error. Missing records, inaccurate assessments of the situation on the ground due to the overwhelming data streaming in, putting the head office staff under strain- it all hampers the productivity of the company. 

Take scheduling for instance. You have different employees, and various jobs that need their attention, at different locations. It can be a plumbing company whose clients have water filters that need to be repaired, gas boilers inspected, leaking pipes fixed, and others who need new installations to be set up. Assigning your personnel to the different situations will need to take into account the type of job, and the amount of time that it will require, aspects such as the location and the crew that is closest to it. At the head office you will want to keep tabs on the jobs that are in progress, pending, complete, those on hold, and even those that have been cancelled. Running all these through traditional manual processes is enough to drive you to the edge. What’s more, tasks that slip through your fingers amidst the confusion will result in negative feedback from your customers- which you don’t want hitting your brand.

With a field service job management software like FieldELite, you get to handle it all from one dashboard. Optimise your service delivery using the accurate scheduler, that allows you to account for the location of your employees, the status of the job- from the urgent ones like emergency tasks, to the normal duties such as routine maintenance, and low-priority tasks. The field service scheduling software comes with a real-time location feature that allows you to determine the employees closest to the client’s premises who will be appropriate for the job, map out the service areas and give you a birds-eye view of all the operations on the ground, while being updated with the progress of each specific task. Less time is spent travelling to- and from the central office, and more on actually tending to your client’s needs. You can even have situations where you can assign end-of-day tasks to employees who will be passing on that route on their way home.

  • Enhanced resource utilisation that promotes personal and professional development

Skill is key across the industries- from electrical services, solar panel installation, landscaping, home remodelling, pest control, plumbing, HVAC system maintenance, to construction and property management. For the job to be done appropriately and make your clients happy, you want to assign the task to an employee who is particularly proficient at it. This tends to be glimpsed over during manual scheduling since the personnel at the head office will be swamped with so many files, and will pick the first one that comes close to fitting the job description, leading to overlapping of roles. Sure, they may get it done, having seen their colleagues do it and even helping them out when they worked together before on similar projects- but will it be up to the required standard? On the other hand, the FSM allows you to ensure that you get the right technician for the task- who will be more motivated, boosting their performance.

What about accidents? Your employees want to feel safe as they go about their mandate. Many of the field service jobs are hazardous- such as electrical repair jobs, window cleaning tasks at high rise buildings, to elevator repair jobs where a slight glitch can lead to severe ramifications. Field service management software also comes in handy here, where the head office can be notified of any emergency the moment it occurs, and arrange for the necessary action to be taken immediately. That way, your employees will not feel neglected while they are out in the field, showing them that their safety is a priority to your business- which in turn increases their morale. 

  • Readily available knowledgebase and feedback system

When the employees have been assigned a specific job, they will require certain information about it. This includes the scope of the task, history of previous repairs or maintenance that was carried out, accompanying images if needed, risk assessment, any hazards or contaminants that they will need to prepare for, to notes left by technicians who had handled it. Having to keep checking their email, or picking up documents at the office for the day’s job and walking around with them all day as they tend to one customer after another, will slow things down, and not to mention frustrate them. However, the FSM system is directly accessible by the employees via app on their phones. The information needed for each specific task will thus be at their fingertips, speeding up the process and ensuring that they will be ready for each project being handled. 

While carrying out the job itself, the employees will use the very same app to update the system on how it is progressing, chat with the staff at the head office, update the inventory and even place orders for extra parts if necessary. Since mobile service management software apps like FieldElite also work in offline mode, the photos, reports and other entries that are made are collected by the app and saved on the device. Once a network connection is established, they are then updated to the central database- thus ensuring that the job can proceed regardless of the location. 

Once the job is completed, the customer input is also taken, registered in the system through their e-signature. A signoff comment included gives the customer the opportunity to indicate their experience with the job, and the feedback that they would like to provide. In case the job has not been completed, then the scheduling software kicks in, putting it in queue for another appointment to take care of the task, or resolve the issue that had caused it not to be completed the first time. The completed tasks head right to invoicing, which is also handled within the field service management platform, making it a seamless task for the head office staff.
