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.

Matrix Management: Benefits and Pitfalls

Matrix management brings together managers and employees from different departments to collaborate with each other towards the accomplishment of the organizational goals. As much as it is beneficial, matrix management also has limitations. Hence, companies should understand its benefits and pitfalls before implementing this management technique.

Benefits

The following are some of the advantages of matrix management:

Effective Communication of Information

Because of the hybrid nature of the matrix structure, it enables different departments to closely work together and communicate frequently in order to solve project issues. This leads to a proficient information exchange among leaders and subordinates. Consequently, it results to developed strategies, enhanced performance and quick productivity.

Efficient Use of Resources

Resources can be used efficiently in the organisation since it can be shared among functions and projects. As the communication line is more open, the valuable knowledge and highly skilled resources are easily distributed within the organisation.

Increased Motivation

The matrix structure promotes democracy. And with the employees working on a team, they are motivated to perform their duties better. The opinions and expertise of the employees are brought to the table and considered by the managers before they make decisions. This leads to employee satisfaction, empowerment and improved performance.

Flexibility

Since the employees communicate with each other more frequently, decision making becomes speedy and response is adaptive. They can easily adjust with diverse situations that the company encounters.

Skills Development

Matrix employees are pooled out for work assignments, even to projects that are not necessarily in line with their skill background. With this approach to management, employees have the chance to widen their skills and expertise.

Discipline Retention

One significant advantage of matrix management is that it enables the employees to maintain their skills in functional areas while working with multidisciplinary projects. Once the project is completed and the team wraps up, the members remain sharp in their discipline technically and return to their home functions.

Pitfalls

Here are some disadvantages of matrix management:

Power Struggle

In the matrix structure, there is always tension between the functional and project manager. Although their intent is polite, their conflicting demands and competition for control over the same resources make it more difficult.

Internal Complexity

Having more than one manager, the employees might become confused to who their immediate leader is. The dual authority can lead to internal complexity and possible communication problems. Worst, employee dissatisfaction and high employee turnover.

Heightened Conflict

In any given situation where people and resources are shared across projects, there would always be competition and conflict. When these issues are prolonged, conflicts will heightened and will lead to more internal problems.

Increased Stress

For the employees, being part of a matrix structure can be stressful. Their commitment is divided among the projects and their relationship with multiple managers requires various adjustments. Increased stress can negatively affect their performance in the long run.

Excessive Overhead Expenses

Overhead administrative costs, such as salaries, increase in a matrix structure. More expenses, more burden to the organisation. This is a challenge to matrix management that leaders should consider carefully.

These are just some of the advantages and disadvantages of matrix management. The list could go on, depending on the unique circumstances that organisations have. The key is that when you decide to implement matrix management, you should recognise how to take full advantage of its benefits and understand how to lessen, if not eradicate, the pitfalls of this approach to management.

Job & Staff Scheduling with FieldElite Mobile Service Management Software

Field Service Management (FSM) software systems are designed to enable you to manage your mobile workforce from a central point- and do away with the paperwork involved with the process. They connect your technicians on the ground (via app on their phones), to the staff at the head office- who have an interactive dashboard accessed through their browsers. The office team will have access to all the jobs that are to be handled by the company, simplifying the management process and taking away the risks that come with manual data entry. Here, we will walk you through a quick process of scheduling a job for your personnel with FieldElite.

Say you are a HVAC contractor, licensed, bonded and insured. You’ve made quite a name for yourself in the industry, and have a wide range of clients- in both residential and commercial establishments. Consequently, you also have a large workforce to attend to the different situations- from installing to repair and maintenance. One of your clients- let’s call them ABC Computer Supplies, has an issue with their HVAC unit- perhaps a pipe is leaking. It needs to be fixed, and ABC have booked an appointment.? Your goal here is to get one of your personnel to handle the task as soon as possible, and this field service scheduling software comes in handy.

There are two approaches that you can take:

1. Job Scheduling

From your Dashboard, on the left-hand side you will see the menu option. Clicking on Jobs, will take you to all jobs carried out by your company.

FieldElite

The filters will allow you to view different categories of jobs:

  • Complaint– This means that there was an issue with on ground during the task delivery, and the client lodged a complaint.
  • On hold– Here, different aspects can cause a job to be paused- like when spare parts or equipment required for repair jobs have been ordered, and one needs to wait for them to be shipped in from a different location.
  • Pending– This is basically your in-tray, a list of jobs that are to be carried out.
  • In Progress– The technicians are on the ground, attending to the client’s needs, and you’re getting routine updates from them.
  • Incomplete– Though the job had been assigned to the required technician, it was not completed in the set amount of time, thus requiring an additional visit to the site. Given that the FSM solution increases the first-time fix rate, cases of ?incomplete tasks? are reduced.
  • Complete– The task is successfully done and the customer has appended their e-signature, and now it can be invoiced.
  • Cancelled Invoice– The head office determines that a particular invoice shouldn’t be paid, and thus cancels it.

Our focus here is the pending tasks, so use this filter. ABC’s HVAC job will be among these. Clicking on its Job ID will open up the details of the task, with such an Update Job window:

FieldElite Job

This section contains all the information of the job- both past and present, which you can update in real-time. Any changes will be recorded by the system and can be viewed on the “Audit” tab.

As you can see here, the HVAC repair job is both “pending” and “urgent”. No one really likes sitting in an office that feels like an oven. Being the headquarters, it’s likely handles lots of foot traffic, and the damaged HVAC unit will make the working conditions really difficult. It’s best not to keep the client waiting, right?

So, head on over to the Supervisor and Workers section (on the same “Details” tab), and select the personnel suited for the task.

FieldElite Job Details

Set the time that the task will take for your technician, and once satisfied with the details of the job, click on Update. Voila! You’re done.

FieldElite Job Update

Immediately this happens, the worker received a notification on their app, telling them that they have been assigned the job.

From the app, the technician will be able to view the specifics of the HVAC job, including notes and attachments that you can add directly from your own dashboard, such as schematics of the building and reports from other technicians who installed the air conditioning system for the facility. You also get to add products that will be required for the task- like the pipe and panel mounted socket shown here. As the system also includes an inventory of the products used, their quantity and costs, you will be able to keep an accurate record of the supplies as they as are used.

As such, the field workers will not have to keep coming back to the central office to get documents and reports of new tasks, or walk around with bulky files. When they are carrying out the job, they will also be able to keep the staff at the office updated about its progress, through the chat feature on the mobile app, taking photos and adding notes as required.

2. Staff Scheduling

With this approach, the perspective is basically: ?So I have a couple of jobs- which of my employees has time to handle them?? The FSM allows you to optimise your productivity- by ensuring that you get the most out of the staff work hours, and avoid cases of jobs going into overtime.

Follow these steps:

  1. Select ?Scheduler? from the left-hand side of the window. You will have a view of the workers of your company and how their day is planned out, and a summary of the unassigned jobs.

Here, you can tell whose busy, and who can have a new task assigned to them at the click of a button- which is far more effective than keeping on jotting down points in your diary or going through files of documents.

If the job has yet to be added to the system- like for the cases of new clients, simply click on the ?Add Job? button and key in its details.

2. Scroll down, you will see a list of unassigned jobs.

unassigned jobs

3. Next, click on the edit button under ?Actions?. This will take you to the same ?Update Job? window described in the first approach, in order to assign the preferred worker to the role.

This real-time dispatching avoids cases of your desk getting cluttered with paper sheets, and prevents duplicate entries as each job has its own ID and task details- from the scheduling to the invoicing. In this case, your HVAC technician will have access to the information needed right at the palm of their hand, to ensure that the task at ABC?s head office goes seamlessly. The optimised schedule will enable the task to be carried out faster- restoring normalcy to your client’s facility.? In case the client’s location is on the route that one of your technicians takes while heading home, you can take advantage of this by giving them the task towards the end of their working day- thus clearing more of your backlog, sorting out your client, and easing your technician?s worries about getting home late.

As you can see, the field service scheduling software enables you to easily and efficiently handle your workflow, avoid the mess that is associated with manual documentation and cases of your employees getting conflicting schedules and overlaps- which would strain them and dampen their morale. Streamlining your workflow and standardising operations ultimately results in increased customer satisfaction.

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.
