Kompostárna Jarošovice

Kompostárna Jarošovice, s.r.o. is a Czech waste-management and composting company based in Jarošovice, about four kilometres north-east of Týn nad Vltavou in the South Bohemian Region. It operates a roughly 14-hectare site that was formerly used for agricultural purposes and specialises in the treatment of organic waste — branches, grass, leaves, soil, sewage-treatment sludge and mud — as well as animal by-products. The company collects and processes this material on behalf of municipalities and commercial kitchens, and it manufactures and sells compost from the resulting output. The business began on 15 October 2009, according to the trade register, when it opened what was then the only facility in the region for processing Category II and III animal by-products under European Regulation 1774/2002, with a specialisation in kitchen leftovers. In 2014 the company added a composting area that doubled its capacity to 20,000 tonnes per year, at a time when it was processing around 7,000 tonnes of biowaste annually. In the same year it started up a biogas plant using wet fermentation, producing roughly 6,500 cubic metres of biogas per day. Compost production relies on aerobic controlled digestion in windrow piles, monitored through temperature measurement, chemical analysis and cress testing. The incoming material is manually inspected, with undesirable components removed especially from food waste. Beyond its core operations, Kompostárna Jarošovice cooperates with municipalities and organisations across the South Bohemian Region. Together with the Biological Centre of the Czech Academy of Sciences it appears at exhibitions such as Země Živitelka and Hobby in České Budějovice, and it runs its own events, including the Autumn Compost Harvest in Týn nad Vltavou. It also offers guided excursions for schools and organises educational activities. The company maintains a public-facing brand presence through its website and regular participation in the Hobby fair, where it has exhibited every year since 2018. At the 2026 edition it distributed 8,200 tulip bags with substrate and provided advice on home composting, while children's activities introduced soil organisms and drawing. The firm presents itself as a regional specialist in biowaste handling and a promoter of domestic composting.

Kompostárna Jarošovice, s.r.o. traces its beginning to 15 October 2009, when, according to the trade register, it opened what was then the only facility in the South Bohemian Region for processing Category II and III animal by-products under European Parliament Regulation 1774/2002, specialising in kitchen leftovers. This established the company as a regional pioneer in handling food waste and other organic materials that required controlled treatment. In 2014 the company expanded its site by adding a composting area, which doubled the plant's capacity to 20,000 tonnes per year. At that time it was processing approximately 7,000 tonnes of biowaste annually. In the same year, it commissioned a biogas plant based on wet fermentation, which produces around 6,500 cubic metres of biogas per day. These investments broadened the company's output from compost alone to include renewable energy. The company operates from a roughly 14-hectare site in Jarošovice, about four kilometres north-east of Týn nad Vltavou, on land previously used for agriculture. Its core activity is the processing of organic waste — predominantly branches, grass, leaves, soil, sewage-treatment sludge and mud — as well as animal by-products. It offers collection and processing as a service to municipalities and commercial kitchens, and it manufactures and sells compost from the treated material. Compost production uses aerobic controlled digestion in windrow piles, with monitoring through temperature measurement, chemical analysis and cress testing. The material is manually inspected to remove undesirable components, especially from food waste. Over the years, Kompostárna Jarošovice has built long-term cooperation with municipalities and organisations across the South Bohemian Region. Together with the Biological Centre of the Czech Academy of Sciences, it appears at exhibitions such as Země Živitelka and Hobby in České Budějovice, and it organises its own events, including the Autumn Compost Harvest (Podzimní kompostobraní) in Týn nad Vltavou. It also allows schools to visit for guided excursions and runs educational events. The company has been a regular participant at the Hobby fair since 2018, missing no edition. At the 2026 fair, held from 14 to 17 May, it distributed 8,200 tulip bags with substrate and provided advice on home composting, while children's activities introduced soil organisms and drawing. The company views its presence at the fair as a way to reach both existing customers and newcomers, including residents of nearby Týn nad Vltavou who may not yet know the firm.
