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.

Choosing Routes for ESOS Compliance

Along the introduction of Energy Savings Opportunity Scheme in UK is the quick emergence of various companies that offer ESOS compliant services. While some energy audit providers can help, qualified businesses should understand what their compliance options are, how these routes work and learn both the pros and cons in order to carefully take their pick.

Independent ISO 50001 Certification

ISO 50001 comprises the integration and application of processes geared to motivate energy saving and overall improvement. Simply stated, it is a framework that drives the organisation’s governance to realise energy saving strategies by allocating resources and participating in energy management. The good thing about ISO 50001 is that it includes an energy review that documents ideas and opportunities to save more energy.

However, ISO 50001 does not obligate organisations to cover 90% of their overall energy consumption. In case of partial coverage, the company needs to undergo additional energy assessments to evaluate all the significant energy consumption areas.

In order for an ISO 50001 certification to be valid, it must be certified by the United Kingdom Accreditation Service (UKAS), by an accreditation body which is a member of the International Accreditation Forum, or by a body accredited by another EU member state?s national accreditation body.

Display Energy Certificates and Green Deal Assessments

These two kinds of energy assessment reports can also contribute to ESOS compliance. Both of them are carried out by qualified lead assessors and valid for 10 years. However, they are only based on the building structures and services. They do not cover the overall significant areas in energy consumption. Since these reports are valid for 10 years, they would be used for two ESOS reporting periods. Thus, they would not be as current as the ISO 50001 certification. Aside from that, the assessments are purely based on energy efficiency and anyone can qualify to use the software that produce the certifications after taking the accreditation course.

Energy Audits

A successful energy audit leads to better understanding of the company?s energy consumption, identify alternatives, determine cost-effective energy saving opportunities and stimulate energy efficiency. Energy audits are beneficial to the organisation. What makes it complex is that the organisation applying it, needs to clearly define the scope and type of energy audit to use in order to comply with ESOS. Furthermore, the organisation also has to identify the teams that would be competent enough to do the audit work for the building, transport and industrial area, respectively.

Each route is not formed equal. Thus, organisations have the option to either choose one or combine the routes and meet their company needs. The options mentioned are different approaches to ESOS and the core value is to grab the opportunity towards acquiring more savings through efficient energy system.

Risk Assessment

Risk assessment is a vital component in BC (Business Continuity) planning. Through risk assessment, your company may determine what vulnerabilities your assets possess. Not only that, you’ll also be able to quantify the loss of value of each asset against a specific threat. That way, you can rank them so that assets that are most likely to cripple your business when say a specific disaster strikes can be given top priority.

However, a poorly implemented risk assessment may also cost you unnecessary expenditures. Many risk assessors are too enthusiastic in pointing out risks that, at the end of the assessment, they tend to over-appraise even those having practically zero probability of ever occurring.

We can assure you of a realistic assessment of your assets’ risks and propose cost-effective countermeasures. These are the things we can do:

  • Identify your unsafe practices and propose the best alternatives.
  • Perform qualitative risk assessment if you want fast results and lesser interruptions on your operations.
  • Perform quantitative risk assessment if you want the most accurate depiction of your risks and the corresponding justifiable costs of each.
  • Conduct frequency and consequence analysis to identify unforeseen harmful events and determine their effects to various components of your organisation and its surroundings.

Telemetry and the Survival of the Human Species

Without moisture, plants die. Without fodder, the animal food chain collapses. This is why climate change is the greatest threat humankind faces. Crop management needs timely information regarding ambient conditions, and also in the soil itself. In dry areas, online knowledge of trends in rainfall, sunlight, wind speed, leaf moisture, air temperature, relative humidity and solar radiation are indicators of soil stress that can be deadly for plants, and everything that relies on them.

As climate change bites, the need to find solutions accelerates. Drones swoop across to monitor ambient conditions, while probes sunk into plants and the earth in which they grow transmit information to big data repositories for feedback to administrators. In Australia, a remarkable cattle farmer is applying the same approach to his herds.

Nuffield scholar Rob Cook has always been on the edgy side of things. He lost his mobility in a helicopter crash in 2008 patrolling farmland but that has not deterred him. If anything, it has freed his mind to explore the potential that telemetry offers farmers in Australia. He shared this potential with the young beef producers in Roma Australia recently, and here is a summary what he said.

Being wheelchair bound he had to shift from herding with cattle dogs to a more scientific approach. He bought a farm 230 miles / 370 kilometres inland from Brisbane in a warm, temperate climate with significant rainfall even in the driest months. He uses observant software that reports on critical issues like water levels indicating animal consumption, and supplementary water flows from a central irrigation channel.

He also monitors fodder sources for dryer months, and moisture levels in food stocks. Rob is committed to making every blade of grass count. ?We even have the ability to take a photo of the cattle when they are taking a drink of water,? he explains, and that provides valuable information regarding tick and fly infestation and overall condition.

None of this would be possible for Rob Cook without telemetry, which is the process of collecting data at remote points and transmitting it to receiving equipment for analysis. Independent farmers do not have equipment to fund these analytic resources on their own, and use big data resources in a cloud to obtain reports. ecoVaro is on top of current trends.
