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.

Total Quality Management

Total Quality Management (TQM) is another business management approach that focuses on the involvement of all members of the organisation to participate in improving processes, products, services, and the culture in which they work in. It is important that every team member realises how each individual and each activity affects, and in turn is affected by, others.

With the use of combined quality and management tools, TQM also aims to reduce losses brought about by wasteful practices, a common concern in most companies. Using the TQM strategy, business would also be able to identify the cause of a defect, thereby preventing it from entering the final product.

Deming’s 14 Points

At the core of the Total Quality Management concept and implementation is Deming’s 14 points, a set of guidelines on quality as conceptualised by W Edwards Deming, one of the pioneers of quality. Deming’s 14 points are as follows:

  1. Create constancy of purpose for improving products and services.
  2. Adopt the new philosophy.
  3. Cease dependence on inspection to achieve quality.
  4. End the practice of awarding business on price alone; instead, minimise total cost by working with a single supplier.
  5. Improve constantly and forever every process for planning, production and service.
  6. Institute training on the job.
  7. Adopt and institute leadership.
  8. Drive out fear.
  9. Break down barriers between staff areas.
  10. Eliminate slogans, exhortations and targets for the workforce.
  11. Eliminate numerical quotas for the workforce and numerical goals for management.
  12. Remove barriers that rob people of pride of workmanship, and eliminate the annual rating or merit system.
  13. Institute a vigorous program of education and self-improvement for everyone.
  14. Put everybody in the company to work accomplishing the transformation.

But if you were to reduce to bare bones the TQM philosophy from Deming’s 14 points, it would all come down to two simple goals:

  1. To make things right the first time; and
  2. To work for continuous improvement.

As with all other quality management process, the end goal is to be able to offer products and services that meet and even exceed customer’s expectations.

Energy Audit – clearly clear?

An energy audit is an examination of an energy system to ensure that energy is being used efficiently. It is the inspection, survey and analysis of energy flows for energy conservation in a building. Energy audits can be conducted by building managers who examine the energy account of an energy system, checks the way energy is used in its various components, checks for areas of inefficiency or where less energy can be used, and identifies the means for improvement.

An energy audit is often used to identify cost effective ways to improve the comfort and efficiency of buildings. In addition, homes/ enterprises may qualify for energy efficiency grants from central government. Energy audits seek to prioritise the energy uses from the greatest to least cost effective opportunities for energy savings.

An energy audit is an effective energy management tool. By identifying and implementing improvements as identified, savings can be achieved not only on energy bills, but also equipment will be able to attain a longer life under efficient operation. All these mean actual dollar savings.

An energy audit has to be conducted by a competent person with adequate technical knowledge on building services installations, after which he/she comes up with a report recommending plans on the Energy Management Opportunities (EMO) for energy saving.

An energy audit culminates to a written report. This could show energy use for a given time period (for example a year) and the impact of any suggested improvements per year. Energy audit reports are then used to identify cost effective ways to improve the comfort and efficiency of buildings. The energy audit report therefore gives management an understanding of the energy consumption scenario and energy saving plans formulation.
Energy audit reports should always translate into action. No matter how well articulated, the energy management objectives are afterall, an energy audit (EMOs), all the effort will be futile if no action is taken. The link between the audit and action is the audit report. It is therefore important for the audit reports to be understandable for all the target audiences/ readers, all of whom may have diverse needs, hence the reason why they should be clear, concise and comprehensible.

What are the do?s and don’ts when writing energy audit reports?

Avoid technical jargon as much as possible; present information graphically; use different graphics such as pie charts, data tables. Schematics of equipment layouts and digital photos tend to make EMO reports less dry. Some of the energy audit software?s come in handy in the generation of such graphs and charts.
The climax of it all is the recommendations, which should be made very fascinating.

When Carrefour Pushed the Right Buttons

Retail giant Carrefour based in Boulogne Billancourt, France is big business in anybody?s numbers. Europe?s #1 retailer opened its first store in 1958 near a crossroads (Carrefour means ?crossroad? in French) and has largely not looked back since then. The slogan for the hypermarket chain with more than 1,500 outlets and close to a half million employees is ?choice and quality for everyone?. Our story begins when Carrefour decided these things belong at home too.

The company implemented a worldwide universal responsibility program firmly anchored on a tripod of goals for environmental, economic and social progress. Its first step was to appoint a five-person project team tasked with liaising with program delegates in all thirty countries in which it operates, and who had responsibility for driving these goals.

The team?s job was to make sure that policies, standards, procedures and key performance areas were common visions throughout Carrefour. By contrast, the local managers? were tasked with aligning these specifics to local conditions in terms of environmental, political and social issues. The project team checked the fit quarterly via video conferences.

The Triple Bottom Line Goals were woven through with Carrefour?s Seven Core Values, namely Freedom, Responsibility, Sharing, Respect, Integrity, Solidarity and Progress. Constant contact was maintained with staff and other stakeholders through ?awareness training? seminars and other dialogues. As the program took hold and flourished, it became evident that the retail giant needed help with managing the constant stream of metrics flowing in.

After reviewing options, Carrefour appointed a software provider to monitor progress against its primary focuses on energy, water, waste, refrigeration, paper, disposable checkout bags, hygiene & quality, management gender parity, disabled people and logistics. This enabled it to track progress online against past performance, and produce meaningful reports.

The Environmental Manager in the Corporate Sustainability Department waxed lyrical when he said, ?We believe that our sustainability strategy and software solution have powerfully improved collaboration, innovation, and overall performance?. He went on to describe how it was helping drive cost down and profitability up, while simultaneously growing brand.

Non-conformance costs can be high and run counter to the imperative to make a profit – while simultaneously ensuring a better world for our children?s children. In Carrefour?s case, having a consultant to measure progress was the key that unblocked the administrative bottleneck. Irish company Ecovaro does this for companies around the world. Click here.
