Glove Waste Recycled through Kimberly-Clark Program

Kimberly-Clark Professional’s, Roswell, Ga., RightCycle Program is the first large-scale recycling initiative for hard-to-recycle and commonly used items including non-hazardous laboratory gloves. The program converts used nitrile gloves, apparel and safety eyewear into new consumer goods. Since its inception in 2011, it’s helped customers divert more than 660 tons of waste from landfills.

The Woods Hole Oceanographic Institution (WHOI; Falmouth, Mass.) is a non-profit organization dedicated to ocean research, exploration and education. Some of his work includes when its researchers teamed up with French scientists in 1985 to discover the Titanic. WHOI sought to reduce waste in its own operations, an obvious target was the high volume of laboratory gloves used by researchers in its facilities.

We recently were contacted by U.K.-based Teysha Technologies, which after more than a decade of research has achieved a landmark breakthrough in creating a viable substitute for existing petroleum-based PC resins, and potentially other plastics

Explains project research scientist Ashlee A. Jahnke, “Our technology uses a plug-and-play system that takes monomers and co-monomers—the natural building blocks that make up plastic—to create a polymer that works and functions in a very similar way to the plastic we’re used to. The difference is that our monomer feedstocks are derived from natural sources such as starches and agricultural waste products, rather than hydrocarbon-based petrochemicals sourced from fossil fuels.”

A mathematical tool that proved to be an effective approach to save time, money and effort in product development for foam extruders, can also be used by various types of plastics processors.This was recently brought to our attention by Abhay Bulsari, owner and president of a Finland-based 22-year-old process and materials development consultancy called Nonlinear Solutions Oy. Here, Bulsari gives us the example applying linear modelling in his work with Finnish PE foam extruder NMC Termonova.

Bulsari’s goal was to help speed up the company’s product development, which included not only improving the quality of its foamed products, but also how to produce better recipes and new products with more demanding combinations of material properties. Explains Bulsari, “We have established how nonlinear models are a powerful tool for materials development as they can contain valuable knowledge in a concise and precise form. A small number of experiments suffices for the development of nonlinear models, if planned suitably. Material properties can be related with the composition variables, process variables and dimension variables effectively using nonlinear modeling.”

While attending the recent Global Plastics Summit (GPS2-18), now in its sixth year and hosted by IHS Markit and the Plastics Industry Association (PLASTICS), I had the opportunity to interview John Thayer, sr. v.p. of PE for Nova Chemicals. Sustainability was a major theme running through this year’s event, and Thayer is among the industry representatives who are fervently seeking solutions to promote a plastics circular economy.

In the short time allotted us during this well-attended and fully-packed event, Thayer gave me a rundown on some of the key areas of focus which include:

How Central Chiller Control Works to Save Energy

No matter how efficient your plastics processing plant is, there are always areas where you could save a little more on energy, and ultimately energy costs. It’s time to take a closer look at your central cooling system.

The function of a process water chiller is to make cold water to cool a mold or other process equipment. As heat transfers from the process to the water, the water warms up. Conventional chillers use a fixed pressure setting based on the warmest summertime temperature experienced. As the ambient air is cooled, the chiller turns fans off of the air-cooled condenser or regulates the flow of cooling tower water to maintain the fixed pressure setting for the condenser.
