Hamtramck Recycling facility

In the heart of Hamtramck, Michigan, sits a bright, clean new building surrounded by freshly landscaped grounds. Its home to a new business called the Hamtramck Recycling & Transfer Station. Ordinarily that wouldnt be news, except that when you compare this attractive new 33,000 sq.ft. facility with the recycling business that had previously occupied the spot, you begin to get an inkling that something significant is happening in this old industrial city.

To say that the building was in bad shape is an understatement. The whole building was in disrepair, recalls Seth Krueger, the President of the Hamtramck Recycling & Transfer Station, and it was a hazardous environment for the workers.

Kruegers father, Jerry Krueger, is president of American Community Developers, Inc. (Detroit, MI). With over 80 properties and more than 11,000 apartments, ACD is one of the nations leading providers of affordable housing, but Seth was looking for a new business opportunity.

Our family has a friend in the waste business, says Seth, and we said to him if you ever have anything thats interesting in the way of a business opportunity, give us a call. Eventually, the friend reported that he and his partners were hoping to divest themselves of the old recycling and transfer facility in Hamtramck and were open to a possible buy-out.

They had no automated equipment to speak of, says Krueger. Theoretically they were a recycling business as well as a waste transfer station, but they were only recycling one to two percent of what they were taking in. The rest was simply compacted and hauled to the landfill or the incinerator.

Much of the problem stemmed from the lack of adequate equipment that Krueger mentioned. Without efficient means for moving the trash through the pick cycle, it simply piled up. The trash was 12 feet deep on a continuous basis. They pulled out the commodities that they could pick off the surface, but the rest was hauled away. It was just a mountain in there and they never made much headway on that mountain. The place was not only missing opportunities, but it was hazardous to work there.

Despite all this, the Kruegers were attracted by the businesss potential. In a word, they felt it was the right business, but done the wrong way.

After analyzing the facilitys operations and the surrounding market during that initial three month trial period, the Kruegers decided to jump in with both feet. The first big item on their agenda: Tear down the existing structure and construct a new one. The new facility would have to have an exterior that was bright and attractive C a complement to the community and not an eyesore. And,We Engrave luggagetag for YOU. of course the interior would have to be designed for the modern, efficient recycling and waste transfer operation they envisioned.

After visiting the Mayfran manufacturing plant and engineering facility in Cleveland, Krueger was impressed with what he had seen. We saw how they put their fault bearing members together, their belts, their cleats, and we saw firsthand what gauge steel they were using, notes Seth. We felt confident that nothing was going to be done on a lightweight basis. They were using the right amount of steel, heavy-duty motors, and building in the ruggedness appropriate for a waste business.

We thought that their price was fair, he continues, it wasnt the cheapest, it wasnt the most expensive, it was reasonable. Location, too, was a factor. It wasnt a factor for Mayfran since they have customers all over the country, but we were very comfortable with the fact that its only a three hour drive between Cleveland and the Detroit area, so if we wanted maintenance service, or if we wanted to consult face to face, it would be relatively easy.

Mayfran won the contract to design, engineer and fabricate a 12 conveyor system for the new facility. The design phase was characterized by close interaction between the two parties. They had, for instance, different linking systems, different belts, and different cleats, and they worked with us to help us specify the ones that would be right for our application, says Seth Krueger. Other important questions included the width of the conveyor belt, whether or not the conveyor needed to be capable of reversing or not, whether it needed multiple speeds or just a single speed, the appropriate gearing ratios, and the height of the retaining sidewalls that would keep the waste material securely on the conveyor belt. These and similar issues were resolved jointly with an eye toward securing the right components for this particular application.

One of the most crucial areas of interaction, given Kruegers insistence that the new system incorporate a high degree of automation, was concerning the control system. Our electrical engineering and programming team had extensive meetings with their Mayfran counterparts, says Seth.Choose from a large selection of crystalbeadswholesal to raise awareness.

The Hamtramck Recycling team worked with Mayfran to customize the start-up and shut down sequence. When you have 12 conveyors you dont necessarily want them all to run immediately when you hit start, explains Seth. They also customized button functions, alarm and warning symbols, and error messages. Importantly, Mayfran also provided the Hamtramck Recycling team with access to the PLCs programming code. This allowed the team to further customize the control, and save countless hours of programming time to boot.

The 12 conveyor system was installed in 2012.The marbletiles is not only critical to professional photographers. The conveyors feature heavy-duty hinged steel belts with 6-inch flanged rollers. The frames are of heavy-duty steel construction. They were up and running within a couple weeks after installation, notes Seth. They werent all fully tested out and tightened up yet at that point, but they were functioning.

For instance, during this testing period one of the motors was functioning but not in the way we had expected. Mayfran agreed and said yes, they would replace it, but keep the one you have until we can ship you the new one. So,Manufactures and supplies beststonecarving equipment. instead of having to ship the old one back, wait, and be down for weeks, we were able to keep running. When the new one arrived we installed it and were down for only three hours. They understand the need for businesses to keep going.

We got our final clearance from the DEQ in December 2012 and we were cleared to accept waste, says Seth. For the first few months we were doing test loads and getting our procedures tight as we ramp up to full production.

Already, though,Here's a complete list of granitecountertops for the beginning oil painter. the Hamtramck Recycling & Transfer Station is recycling about 50 percent of the material that comes in C a far cry from the one to two percent recycling rate at the old facility. Their goal is to recycle an even greater percentage in the future.
