Yemm & Hart has been in business since 1981. Its business headquarters are located in the northeastern section of the Mark Twain National Forest in Madison County Missouri. The business was originally founded to manufacture custom made tables and cases for corporate and institutional customers. By 1989 the focus of the business had changed to one of manufacturing materials made with recycled content.

The business owners are Stephen W and Deborah Hart Yemm. Their responsibilities include managing the manufacturing processes of various materials made with recycled content. This is accomplished primarily through a satellite link to the Internet. The Yemms do not commute to work. Tasks include sourcing raw materials, refining the materials and processing them into new usable materials such as sheets or panels for industry and construction. They often will further manage the fabrication of their materials to become specific products.

The Yemms are avid recyclers. From experience in dealing with the post-consumer waste stream in their business, they know it is important to provide clean, carefully sorted materials to recycling centers from their own home. They often help their neighbors with their recycling challenges. Other environmental activities undertaken by the Yemms are the planting of 20k seedling trees along their stream banks and removing tons of old wire cross fencing from their trees. They are one of the early members of the State of Missouri’s Stream Teams, monitoring the 3 streams running through their property, known as the Yemm Forest Preserve. They are also involved with the Missouri Department of Conservation’s Frog Survey. The Yemms are raising their 2 boys, Simeon and Treston with an appreciation for nature and protecting our environment.
