Process technology is used in petroleum refining, mining, milling, power generation, waste and wastewater management, food and beverage production, pharmaceutical and chemical manufacturing, and many other industries. Industries of all types require workers to implement and operate the technology used in the production process. These individuals are called process technicians. A process technician may be responsible for controlling and monitoring process systems, testing products, and troubleshooting equipment. There is an ongoing demand for qualified process technicians who can work with instrumentation and equipment and understand safety measures. In addition, process technicians must have good communication skills, be able to maintain accurate data logs and prepare reports, and work effectively in a team environment. example of process technology is the method by which plastic bottles are recycled into thread. Plastic bottles and other containers made of polyethylene terephthalate (PET) can be converted into new products such as fabrics for clothing. The containers are sorted by colour and inspected and cleaned so that any non-PET materials (such as bottle caps or other foreign materials) are removed. The clean containers are then crushed and chopped into small flakes, which can be melted and formed into thread.
