The recycling rate for municipal solid waste exceeds 50 percent [2] (with an objective of 60 percent in 2020 [1]). However, although the recycling rate of 54 percent is above the European average of 28 percent (2015), Switzerland is among the largest waste producers in Europe (730 kg of waste per capita in 2014).

Vector graphics software can be used for manual graphing or for editing the output of another program. Please see: Category:Vector graphics editors; Comparison of vector graphics editors; A few online editors using vector graphics for specific needs have been created.
American and European patent applications relating to the production of plastic shopping bags can be found dating back to the early 1950s, but these refer to composite constructions with handles fixed to the bag in a secondary manufacturing process. The modern lightweight shopping bag is the invention of Swedish engineer Sten Gustaf Thulin. [7]
Selective non-catalytic reduction (SNCR) is a method to lessen nitrogen oxide emissions in conventional power plants that burn biomass, waste and coal.The process involves injecting either ammonia or urea into the firebox of the boiler at a location where the flue gas is between 1,400 and 2,000 °F (760 and 1,090 °C) to react with the nitrogen oxides formed in the combustion process.
Sodium triphosphate (STP), also sodium tripolyphosphate (STPP), or tripolyphosphate (TPP), [1]) is an inorganic compound with formula Na 5 P 3 O 10.It is the sodium salt of the polyphosphate penta-anion, which is the conjugate base of triphosphoric acid.
A* is often used for the common pathfinding problem in applications such as video games, but was originally designed as a general graph traversal algorithm. [4] It finds applications in diverse problems, including the problem of parsing using stochastic grammars in NLP. [26] Other cases include an Informational search with online learning. [27]
