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.

Competencies, Roles and Responsibilities of Lead Assessors

Any organisation that opts for energy audits, Display of Energy Certificates and Green Deal Assessments needs a lead assessor to review the chosen ESOS compliance routes. The Derivative provides that energy audits should be carried out independently by qualified and accredited experts. Additionally, these audits should be implemented as well as supervised by independent authorities under the national legislation.

Lead assessors undertake several roles in ESOS assessments. He or she is the one responsible to take the lead of the entire assessment team, prepare the plan, conduct the meetings and submit the formal report to governing authorities. Nevertheless, selecting an appropriate lead assessor is an important element that every organisation should carefully consider.

Competencies Requirements of Lead Assessors

Lead assessors should be knowledgeable enough with in-depth expertise in carrying out energy efficiency assessment. They should also possess foundational, functional and technical competencies to deliver the task effectively. Likewise, consider the assessors? sector experiences, familiarity with your business? technologies and properties, and accreditation with prescribed standards.

As you choose your lead assessor, contemplate on the skills and qualifications that would give your organisation benefits.

Roles and Responsibilities of Lead Assessors

The business organisation is responsible for the overall legal ESOS compliance. Moreover, here are some of the roles and responsibilities that lead assessors should assume in ESOS assessments.

The lead assessor agrees on the audit methodologies that the organisation would undergo in new audits. He or she agrees with the ESOS participant regarding the audit timetable, sampling approach and visits required. It is also the lead assessor?s role to identify the opportunities on energy saving and assist in calculating the cost savings from the measures taken. During the ESOS audits, the lead assessor determines the energy use profiles, presents the recommendations and reviews the entire assessment as a whole. Furthermore, he or she should maintain the evidence pack of the ESOS to uphold the audit’s credibility, its findings and recommendations.

Finding Lead Assessors

Energy and environment professionals would only be able to demonstrate their expertise as lead assessors upon registering in a professional body accredited by the Environment Agency. Any business that needs a lead assessor is advised to check on the EA?s website to see the details of approved registers.

Lead assessors can either be in-house experts or external professionals. However, they should be able to provide proof of membership as an approved register to take the role of a lead assessor. If the organisation has an internal lead assessor, the company should then take the final ESOS assessment to two board-level directors that would sign the formal report.

Indeed, the lead assessor is an organisation’s partner when it comes to delivering great results. With good professional conduct and excellent management of an assessment team, the lead assessor can help achieve breakthrough energy efficiency strategies. More than anything else, the organisation will benefit from maximum energy savings opportunities ahead. Thus, every qualified business enterprise should invest in finding the best lead assessor to guide them towards success.

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.

What ISO 14001 Status did for Cummins Inc.

Cummins manufactures engines and power generation products, and has been a household name almost since inception in 1919. It sells its products in over 300 countries, through approximately 6,000 dealerships employing 40,000 people. Because its product line runs off fossil fuel it is under steady pressure to display a cleaner carbon footprint.

Cummins decided to go for the big one by qualifying for ISO 14001 certification. This is a subset of a family of standards relating to managing environmental impact while complying with all applicable legislation. In this sense, it is similar to the ISO 9000 quality management system, because it focuses on how products are produced (as opposed to how those products perform). Compliance with ISO 14001 was a doubly important goal, because it is part of the European Union?s Eco Management and Audit Scheme and fast becoming mandatory on suppliers to governments.

The qualification process follows the well-established principle of plan, do, check, act. It begins with gap analysis to detect materials and processes that affect the environment. This is followed by implementation of necessary changes affecting operations, documentation, emergency strategies and employee education. The third step involves measuring and monitoring performance. Finally, the project moves into a phase of ongoing maintenance, and continuous improvement as circumstances change.

In Cummins case, the project was almost worldwide and called for environmental, health and safety reporting throughout the organisation. The information was shared via a globally accessible document repository, and then processed centrally at the head office in Columbia, Indiana USA.

Measuring environmental performance almost inevitably has other benefits that make it doubly worthwhile. Speaking at the 2014 National Safety Council Congress after receiving the top award for excellence, Cummins chairman and ceo Tom Linebarger commented on a journey that was ?nothing short of amazing? yet wasn’t even a ?pathway to the finish line?.

?All of us feel like we have way more to do to make sure that our environment is as safe as it could be,? he added, ?so that our sustainability footprint is as good as it can be and that we continue to set more aggressive goals every year. That’s just how we think about it.? Linebarger concluded.

If you are taking your company on a journey to new heights of environmental excellence, then you should consider choosing ecoVaro as your travelling companion. We are environmental management specialists and have proprietary software geared to process your data. We also have a wealth of experience, and a treasure chest of roadmaps to help you achieve your goal.
