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.

Which Services to Share?

It often makes sense to pool resources. Farmers have been doing so for decades by collectively owning expensive combine harvesters. France, Germany, the United Kingdom and Spain have successfully pooled their manufacturing power to take on Boeing with their Airbus. But does this mean that shared services are right in every situation?

The Main Reasons for Sharing

The primary argument is economies of scale. If the Airbus partners each made 25% of the engines their production lines would be shorter and they would collectively need more technicians and tools. The second line of reasoning is that shared processes are more efficient, because there are greater opportunities for standardisation.

Is This the Same as Outsourcing?

Definitely not! If France, Germany, the United Kingdom and Spain has decided to form a collective airline and asked Boeing to build their fleet of aircraft, then they would have outsourced airplane manufacture and lost a strategic industry. This is where the bigger picture comes into play.

The Downside of Sharing

Centralising activities can cause havoc with workflow, and implode decentralised structures that have evolved over time. The Airbus technology called for creative ways to move aircraft fuselages around. In the case of farmers, they had to learn to be patient and accept that they would not always harvest at the optimum time.

Things Best Not Shared

Core business is what brings in the money, and this should be tailor-made to its market. It is also what keeps the company afloat and therefore best kept on board. The core business of the French, German, United Kingdom and Spanish civilian aircraft industry is transporting passengers. This is why they are able to share an aircraft supply chain that spun off into a commercial success story.

Things Best Shared

It follows that activities that are neither core nor place bound – and can therefore happen anywhere ? are the best targets for sharing. Anything processed on a computer can be processed on a remote computer. This is why automated accounting, stock control and human resources are the perfect services to share.

So Case Closed Then?

No, not quite. ?Technology has yet to overtake our humanity, our desire to feel part of the process and our need to feel valued. When an employee, supplier or customer has a problem with our administration it’s just not good enough to abdicate and say ?Oh, you have to speak to Dublin, they do it there?.

Call centres are a good example of abdication from stakeholder care. To an extent, these have ?confiscated? the right of customers to speak to speak directly to their providers. This has cost businesses more customers that they may wish to measure. Sharing services is not about relinquishing the duty to remain in touch. It is simply a more efficient way of managing routine matters.

Spend more to reduce costs?

It is becoming increasingly important to not to analyse energy consumption for all utility types, be it electricity, gas, water, heat, renewables, oil etc. The bottom line is both operational efficiency and utility costs monitoring. In the long run, these are management strategies designed to drive energy costs downwards as a continuous improvement cycle and as a measure of reducing carbon emissions.

It is also getting increasingly easier for organisations reduce energy use and achieve this goal using technology without having to “remember” to do it yourself. Organisations can never go wrong by investing in energy management software. There are varied software options to choose from depending on the organisational objective.
Some of the energy management objectives that organisations may need to meet are:

? Establishing baseline energy use

? Carrying out Energy audits

? Monitoring and measuring energy performance against the energy policies of an organisation and objectives

? Achieving energy certification
Energy management software?s come in handy when an organization wishes to achieve either of the above objectives.

Use of energy management software?s also assists organisations in measurement and verification of energy consumption as well as Monitoring and Targeting. Measurement and verification is where a company quantifies energy consumption beforehand (baseline energy use) and after energy consumption measurements are implemented in order to verify and report on the level of savings actually achieved.

Organisations that wish to verify the energy savings achieved by building retrofits can use energy management software?s. This is an important objective for companies that wish to either satisfy internal financial accounting and reporting requirements, or to meet the terms of third-party contracts for project implementation and management. Monitoring and targeting is also made easier by use of software. This is critical as a management technique, regardless of whether an organisation has specific facility retrofits in order to keep operations efficient and to monitor utility costs.
Overall, an investment in energy management software, is worthwhile in the achievement of management strategies designed to drive energy costs downwards as a continuous improvement cycle.

Recognizing Your Carbon Footprint

Countless times we have heard of the term ?carbon footprint?. Perhaps we have seen and heard it on TV or read it in newspapers, magazines and published articles. Indeed, it has been an expression familiar to everyone as it is always associated with climate change, carbon emissions, global warming, pollution and other environmental issues. Carbon footprint is real. It exists and, in fact, continues to affect the world we live in.

Defining Carbon Footprint

Two essential words comprise the term carbon footprint. Fundamentally, ?carbon? means the carbon dioxide circulating in the atmosphere. It is also the general word used for other greenhouse gasses emitted into the air. On the other note, ?footprint? refers to impact or effect.

Think about the footprints people leave on the beach sand upon walking on the shore. That is exactly what carbon footprint is like. It’s about the impact humans leave on the earth in the form of carbon dioxide and other greenhouse gases.

Calculating Your Personal Carbon Footprint

The food we eat, products we use, vehicles we ride on and electricity we consume emit carbon dioxide. In fact, our activities, lifestyle, homes, and countries contribute to climate change. And carbon footprint is the best estimate we can get of the full impact our doings affect the earth. It quantifies the amount of our carbon emission. With this, knowing how to calculate your personal carbon footprint is important.

There are various standards in calculating one?s carbon footprint. There is the so-called ?lifestyle assessment? and the input-output analysis. Lifestyle assessment works by adding up all the feasible emission pathways while the input-output analysis involves determining the total emissions of a particular country, dividing it by the carbon-emitting sectors and estimating the overall emissions of each sector. The input-output analysis makes sure that no emission pathway is missed out.

Calculating your carbon footprint manually is an effective way for you to understand your emissions better. You just need a lot of patience to learn how each footprint is generated. Moreover, there are also several resources online that can help you calculate your carbon footprint. Online carbon calculators are abundant across the web. To make your life simpler, you can opt to try those online calculators and easily determine your carbon emissions. However, such calculators vary in scope. So make sure that the online carbon calculator, you choose, is one that?includes emissions both direct and indirect.

Avoiding Toe Prints

A toe print is a portion of a footprint. Sometimes, people are misled in their calculations because they only get a carbon toe print instead of a footprint. The idea is that, you should cover a smart scope of your carbon emissions. Not only measuring a portion, but the whole.

Say for example, running a conventional car. The carbon emitted from the car is not only the fuel combustion from the diesel or petrol.? Likewise, the carbon released as the gas was processed and transported to your nearby gasoline station is also an addition to your carbon footprint. If you do not understand this, you will end up calculating your direct emissions while neglecting the indirect ones.

Be wise in calculating your carbon footprint. And when in doubt, whether you are an individual or a business entity, you should seek help from experts who can do it right.
