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.

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

Making Click-and-Collect click

In my previous post, I introduced you to integrated e-commerce and explained why it is the right way to extend your business online. If you already have a brick-and-mortar retailing business and you’re looking to improve your online presence, you could start offering a click-and-collect service.

With click-and-collect, customers order online and then collect their merchandise from one of the retailer?s local branches. Why would they want to do that?

Apparently, there are buyers who now prefer a click-and-collect service over the delivery service of a purely online retailer. With the latter, they sometimes have to wait forever for the delivery van to arrive or contend with a missed-delivery card.

Basically, customers who want both the convenience of placing orders online and better control of their time find click-and-collect a better option.

Last December 2011, IMRG (Interactive Media in Retail Group) reported a ?significant rise in the percentage of click-and-collect e-retail sales in the 3rd quarter of 2011?. This accounted for 10.4% of all e-retail sales in that quarter. More specifically, the gain was 7.4%, which was also the strongest quarterly gain since IMRG started collecting this data.

Clearly, this particular service is gaining popularity. But how do you meet the rising demand in this area?

A click-and-collect service requires a highly synchronised ecosystem. You don’t want to have a customer order items from your online store, drive a couple of minutes from his house to your nearest outlet, only to find out that one of the items is no longer available.

This can only work if all systems involved are interconnected. Changes in the inventory in your individual outlets should reflect on your database in real time. In turn, these changes have to be reflected instantly on your online store. Conversely, once a buyer has picked items online and is already directed to a local outlet, those items have to be reserved there.

But that’s not all. Your system has to be seamless enough to support fast and reliable service. You don’t want your buyer to have to wait a long time before the items are ready for pick-up. It also has to be capable of tracking the status of ordered products, handling uncollected orders, and monitoring inventory.

By implementing an integrated e-commerce system, these won’t be the only things you?d be able to do. You can even add more value to your service. For example, you can connect to your CRM and learn more about your customers? purchase history, buying habits, and preferences.

That way, it would be easier for you to provide a faster and more convenient buying experience for them in the future.

Click-and-collect is a very promising way to increase your sales and improve customer loyalty.

How Volvo Dublin achieved Zero Landfill Status

The sprawling New River Valley Volvo plant in Dublin, Virginia slashed its electricity bill by 25% in a single year when it set its mind to this in 2009. It went on to become the first carbon-neutral factory in 2012 after replacing fossil energy with renewable power. Further efforts rewarded it with zero-landfill status in 2013. ecoVaro decided to investigate how it achieved this latest success.

Volvo Dublin?s anti-landfill project began when it identified, measured and evaluated all liquid and solid waste sources within the plant (i.e. before these left the works). This quantified data provided its environmental project team with a base from which to explore options for reusing, recycling and composting the discards.

Several decisions followed immediately. Volvo instructed its component suppliers to stop using cardboard boxes and foam rubber / Styrofoam as packaging, in favour of reusable shipping containers. This represented a collaborative saving that benefited both parties although this was just a forerunner of what followed.

Next, Volvo?s New River Valley truck assembly plant turned its attention to the paint shop. It developed methods to trap, reconstitute and reuse solvents that flushed paint lines, and recycle paint sludge to fire a cement kiln. The plant cafeteria did not escape attention either. The environment team made sure that all utensils, cups, containers and food waste generated were compostable at a facility on site.

The results of these simple, and in hindsight obvious decisions were remarkable. Every year since then Volvo has generated energy savings equivalent to 9,348 oil barrels or if you prefer 14,509 megawatts of electricity. Just imagine the benefits if every manufacturing facility did something similar everywhere around the world.

By 2012, the New River Valley Volvo Plant became the first U.S. facility to receive ISO 50001 energy-management status under a government-administered process. Further technology enhancements followed. These included solar hot water boilers and infrared heating throughout the 1.6 million square foot (148,644 square meter) plant, building automation systems that kept energy costs down, and listening to employees who were brim-full with good ideas.

The Volvo experience is by no means unique although it may have been ahead of the curve. General Motors has more than 106 landfill-free installations and Ford plans to reduce waste per vehicle by 40% between 2010 and 2016. These projects all began by measuring energy footprints throughout the process. ecoVaro provides a facility for you to do this too.
