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.

What GDPR Means in Practice for Irish Business

The General Data Protection Regulation (GDPR) is a European directive aimed at ring-fencing consumer data against illegal or unnecessary access. There is nothing to discuss or debate with local politicians, or the Irish Data Protection Commissioner for that matter. As a European directive, it has over-riding power. To obtain an English version, please visit this link, and select ?EN? from the table of languages.

As you reach for your tea, coffee or Guinness after sighting it, you will be glad to know the Irish Data Protection Commissioner has the lead in turning this into business English we understand. The following diagram should assist you to obtain a quick overview of the process we all have to go through. In this article, we briefly describe what is inside Boxes 1 to 12. The regulation comes into force on 25 May 2018 so we have less than a year to get ready.

The 12 Essential Steps to Implementing the General Data Protection Act

1. Create awareness among your people of what is coming their way. The GDPR has given our regulator discretion to dish out fines up to ?20,000,000 (or 4% of total annual global turnover, whichever is greater) so there is determination to make this happen.

2. Become accountable by understanding the consumer data you hold. Why are you retaining it, how did you obtain it, and why did you originally collect it. Now you know it is there, how much longer will you still need it? How secure is it in your hands, have you ever shared it?

3. Open a communication channel with your staff, your customers, and anyone else using the data. Share how you feel about how accountable you have been with the information in the past. Explain how you plan to comply with the GDPR in future, and what needs to change.

4. Understand the personal privacy entitlement of the subjects of the information. They have rights to access it, correct mistakes, remove information, restrict its use, decline direct marketing, and copy it to their own files. What needs to change in your systems to assure these rights?

5. Issue a policy for allowing consumers access to their information you hold. You must process requests within a month, and you may not charge for the service unless your cost is excessive. You may decline unfounded or excessive demands within your policy guidelines.

6. Adapt to the requirement that you must have a legal basis for everything you do with, and to consumer data. You need to be in a position to justify your actions to the Irish Data Protection Commissioner in the event of a complaint. Having a legitimate interest is no longer sufficient.

7. Ensure that consumer consent to collect, use, and distribute their data is ?freely given, specific, informed, and unambiguous.? From 25 May 2018 onward, this consent will be your only ground to do so. You cannot force consent. Your benchmark becomes what the GDPR says.

8. Issue rules for managing data of underage subjects. This is currently under review and we are awaiting results. Put systems in place to verify age. Set triggers for where guardians must give consent. Make sure age is verifiable. Use language young people understand.

9. Introduce a culture of openness and honesty, whereby breaches of the GDPR are detected, reported, investigated, and resolved. You will have a duty to file a GDPR report with the Data Protection Commissioner within 72 hours, thus it is important to fast track the process.

10. Introduce a policy of conducting a privacy assessment before taking new initiatives. The GDPR calls for ?privacy by deign?, and we need to engineer it in. This may be the right time to appoint a data controller in your company, and start implementing the GDPR while you have time.

11. You may also need to appoint a data protection officer depending on the size of your business. Alternatively, you need to add managing data protection compliance to an employee?s duties, or appoint an external data-protection compliance consultant.

12. Finally, and you will be glad to know this is the end of the list, the GDPR has an international flavour in that multinational organisations will report into the EU Lead Supervisory Authority. This will manage the process centrally while consulting national data authorities.

The GDPR is a project we all need to complete. If we are out of line, it is in our interests to get things straightened out. Once everything is in place, the task should not be too onerous. Getting there could be the pain.

ecoVaro to tackle water stress

For many people within the UK, water is not really something to worry about. Surely enough of it falls out the sky throughout the year that it does feel highly unlikely that we?ll ever run out of it. There certainly does seem to be an abundance of Branded Water available in plastic bottles on our supermarket shelves.

Water, water, every where,
And all the boards did shrink;
Water, water, every where,
Nor any drop to drink.

The Rime of the Ancient Mariner ? Samuel Taylor Coleridge

Despite this, Once-unthinkable water crises are becoming commonplace.  If you consider that In England and Wales, we use 16 billion litres of clean drinking water every day ? that’s equivalent to 6,400 Olympic sized swimming pools.

Currently, water companies can provide slightly more than we need ? 2 billion litres are available above and beyond what we’re using.  In some areas, though, such as south east England, there is no surplus and, as such, these regions are more likely to face supply restrictions in a dry year.

If we take little moment to reflect on some of the most notable water related stories over the past few years, we’ll start to get a picture of just how real the potential and the threat of water shortages can be.

Reservoirs in Chennai, India?s sixth-largest city, are nearly dry right now. Last year, residents of Cape Town, South Africa narrowly avoided their own Day Zero water shut-off.

It was only year before that, Rome rationed water to conserve scarce resources.

Climate change is likely to mean higher temperatures which may drive up the demand for water (alongside population growth) and increase evaporation from reservoirs and water courses during spring and summer.

The impact of climate change on total rainfall is uncertain, but the rain that does fall is likely to arrive in heavier bursts in winter and summer. Heavier rain tends to flow off land more quickly into rivers and out to sea, rather than recharging groundwater aquifers.

A greater chance of prolonged dry periods is also conceivable.  This combined with the harsh reality that no human population can sustain itself without sufficient access to fresh water.

If present conditions continue, 2 out of 3 people on Earth will live within a water-stressed zone by 2025

What is water stress?

Water stress is a term used to describe situation when demand for water is greater than the amount of water available at a certain period in time, and also when water is of poor quality and this restricts its usage. Water stress means deterioration in both the quantity of available water and the quality of available water due to factors affecting available water.

Water stress refers to the ability, or lack thereof, to meet human and ecological demand for water. Compared to scarcity, water stress is a more inclusive and broader concept.

Water Stress considers several physical aspects related to water resources, including water scarcity, but also water quality, environmental flows, and the accessibility of water.

Supply and Demand

Major factors involved when water scarcity strikes is when a growing populations demand for water exceeds the areas ability to service that need.

Increased food production and development programs also lead to increased demand for water, which ultimately leads to water stress.

Increased need for agricultural irrigation in order to produce more crops or sustain livestock are major contributors to localised water stress.

Overconsumption

The demand for water in a given population is fairly unpredictable.  Primarily, based on the fact that you can never accurately predict human behaviour and changes in climate.

If too many people are consuming more water than they need because they mistakenly believe that water is freely available and plentiful, then water stress could eventually occur.

This is also linked to perceived economic prosperity of a give region.  Manufacturing demand for water can have huge impact regardless whether water is actively used within the manufacturing process or not.

Water Quality

Water quality in any given area is never static.  Water stress could happen as a result of rising pollution levels having a direct impact on water quality.

Water contamination happens when new industries either knowingly or unknowingly contaminate water with their industrial practices.

Largely, this can happen and frequently does so because these industries do not take effective control of monitoring and managing their impact on communal water supplies.  Incorrectly assuming this is the responsibility of an additional third party like the regional water company.

The truth is, water quality and careful monitoring of it is all of our responsibility.

Water Scarcity

Simple increases in demand for water can in itself contribute to water scarcity. However,  these are often preceded by other factors like poverty or just the natural scarcity of water in the area.

In many instances, the initial locations of towns or cities were not influenced by the close proximity of natural resources like water, but rather in pursuit of the extraction of other resources like Gold, Coal or Diamonds.

For Instance, Johannesburg,  South Africa is the largest City in South Africa and is one of the 50 largest urban areas in the world. It is also located in the mineral rich Witwatersrand range of hills and is the centre of large-scale gold and diamond trade.

Johannesburg is also one of the only major cities of the world that was not built on a river or harbour.   However, it does have streams that contribute to two of Southern Africas mightiest rivers – Limpopo and the Orange rivers.  However, most of the springs from which many of these streams emanate are now covered in concrete!

Water Stress and Agriculture

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 real-time data and utilize cloud-based storage and processing power to curate it.

Sentek?s technology can be found in remote places like 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 repositioned to other locations as crops rotate.

Peter Buss is convinced that measurement is a means to an end and only the beginning. ?Too often, growers start watering when plants don’t really need it, wasting water, energy, and labour. By accurately monitoring water can be saved until when the plant really needs it.

Peter also emphasises that 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.

A Quarter of the World?s Population, Face High Water Stress

Data from WRI?s Aqueduct tools reveal that 17 countries ? home to one-quarter of the world?s population?face ?extremely high? levels of baseline water stress, where irrigated agriculture, industries and municipalities withdraw more than 80% of their available supply on average every year. 

Water stress poses serious threats to human lives, livelihoods and business stability. It’s poised to worsen unless countries act: Population growth, socioeconomic development and urbanization are increasing water demands, while climate change can make precipitation and demand more variable.  

How to manage water stress

Water stress is just one dimension of water security. However, like any challenge, its outlook depends on adequate monitoring and management of environmental data.

Even countries with relatively high water stress have effectively secured their water supplies through proper management by leveraging the knowledge they have garnered by learning from the data they gathered.

3 ways to help reduce water stress

In any geography, water stress can be reduced by measures ranging from common sense to innovative technology solutions.

There are countless solutions, but here are three of the most straightforward:

1. Increase agricultural efficiency: The world needs to make every drop of water go further in its food systems. Farmers can use seeds that require less water and improve their irrigation techniques by using precision watering rather than flooding their fields.

Businesses need to increase investments to improve water productivity, while engineers develop technologies that improve efficiency in agriculture.

Consumers can reduce food loss and waste, which uses one-quarter of all agricultural water.

2. Invest in grey and green infrastructure:  D Data produced by Aqueduct Alliance  –  shows that water stress can vary tremendously over the year.  WRI and the World Bank?s research shows that built infrastructure (like pipes and treatment plants) and green infrastructure (like wetlands and healthy watersheds) can work in tandem to tackle issues of both water supply and water quality.

3. Treat, reuse and recycle:  We need to stop thinking of wastewater as waste.

Treating and reusing it creates a ?new? water source.

There are also useful resources in wastewater that can be harvested to help lower water treatment costs. For example, plants in Xiangyang, China and Washington, D.C. reuse or sell the energy- and nutrient-rich byproducts captured during wastewater treatment.

Summary

The data is undeniably clear, there are very worrying trends in water.

Businesses and other other organisations need to start taking action now and investing in better monitoring and management, we can solve water issues for the good of people, economies and the planet. We collectively cannot kick this can down the road any further, or assume that this problem will be solved by others.

It is time, for a collective sense of responsibility and for everyone to invest in future prosperity of our Planet as a collective whole.  Ecological preservation should be at the forefront of all business plans because at the end of the day profit is meaningless without an environment to enjoy it in!

EU Energy Efficiency Directive & UK?s ESOS

In 2012 the European Union passed its EU Energy Efficiency Directive (EED) into law. This aims to reduce overall energy consumption by 20% by 2020. It placed an obligation on member states to pass back-to-back local legislation by June 2014.

EED Guidelines

The EED provides specific guidelines it expects member nations to address. The list is long and here are a few excerpts from it:

  • Large companies must use energy audits to identify ways to cut their energy consumption
  • Small and medium companies must be incentivised to voluntarily take similar steps
  • Public sector bodies must purchase energy-efficient buildings, products and services
  • Private energy-consumers must be empowered with information to help manage demand
  • Energy distributors / resellers must cut their own consumption by 1.5% annually
  • Legislators are free to substitute green building technology e.g. through better insulation
  • Every year, European governments must audit 3% of the buildings they own

Definition of Energy Audit

An energy-consumption audit is a question of measuring demand throughout a supply grid, with particular attention to individual modules and high demand equipment. While this could be an exercise repeated every four years to satisfy ESOS, it makes more sense to incorporate it into the monthly energy billing cycle.

Because energy use is not consistent but varies according to production cycle, this can produce reams of printouts designed to frustrate busy managers. ecoVaro offers an inexpensive, cloud-based analytic service that effortlessly accepts client data and returns it in the form of high-level graphic summaries.

Potential ESOS Beneficiaries

As many as 9,000 UK companies are obligated to do energy audits because they employ more than 250 employees, have a balance sheet total over ?36.5m or an annual turnover in excess of ?42m. Any smaller enterprise that finds energy a significant input cost, should also consider enlisting Ecovaro to help it to:

  • Obtain a better understanding of the energy side of their business
  • Achieve energy savings and share in a estimated ?3bn bonanza to 2030
  • Reduce carbon emissions to help meet their CRC commitments

More About ecoVaro

We offer web-based energy management software that helps you measure and manage energy costs. This strips data from your meters and generates personalised reports on a dashboard you control. This information helps you accurately zoom in on worthwhile opportunities. With Ecovaro on your side, ESOS truly becomes an Energy Saving OPPORTUNITY Scheme.
