Bacteria are a problem that occurs naturally in dishwashers when the dish stands there dirty for an extended period of time. To get rid of the unpleasant smell that the bacteria is causing, the most common solution is to run a regular washingcycle which can cause problems for the environmentally-conscious consumers since this causes unnecessary energy waste and emissions of chemicals in the washwater. To solve the problem in a more environmentally-friendly way by directly attacking the bacteria with an appropriate bacterialreductionmethod can therefore be an attractive feature in a dishwasher. There are many different ways to treat surfaces that have been exposed to the bacteria. Some high-profile methods are UV-radiation, microwaves and oxidant (ozone) that all three have had success in reducing bacteria in different contexts.

Increased demand for fresh round timber and the need to decrease the amount of tied-up capital has made the forest industry reduce its inventory levels. This has brought on a higher demand on the timber supply from the forest management districts concerning both delivery in time and assortment output.
