Alelyckan Recycling Park was developed as a pioneering facility, where objects regarded as waste are received, repaired, processed and sold on site, creating a circular loop. Alelyckan Recycling Park has a covered sorting hall where trained staff help people sort their waste materials correctly. Items that can be reused are set aside and taken to one of the shops in the Recycling Park. Once this is complete, visitors continue to the recycling centre and dispose of their material in the designated places.

The need to reduce the impacts of deteriorating quality of public waters (particularly enclosed water bodies, etc.) as a result of climate change, in areas that may face declining sanitation conditions. Particularly applicable in response to the need to mitigate impacts in regions where water pollution is occurring due to urban population growth associated with economic growth, or due to rapid industrial development.

Riparian buffers are vegetated, often forested, areas (“strips”) adjacent to streams, rivers, lakes and other waterways protecting aquatic environments from the impacts of surrounding land use. To the extent possible riparian buffers should compose of native species and typically are divided in three zones with a total width of 15 to 200 meters. The first zone should consist of different grasses, a middle zone planted with bushes and a last part with large trees.

The EcoSan waterless toilet is a sanitation system that converts human waste into dehydrated compostable material. The waste can then be used as compost or disposed of at a traditional waste management facility. The EcoSan requires neither water nor sewer access to function. It eliminates the cost and infrastructural barriers associated with the installation of sewer and water systems while removing the negative health and environmental effects of open defecation. It is particularly relevant to improving sanitation in rural communities

1. Outline Cupric chloride etchant waste is discharged from the print circuit board manufacturers. The etchant waste is characterized by a very low pH and high cupric ion and chloride ion concentrations. The EOCOR Process is an on-site recycling technology of the cupric etchant waste. And the product of EOCOR Process is cupric oxide which can be used as a raw material of plating process. For on-site recycling technologies one of the biggest challenges is to avoid chloride contamination.

Landfills to treat solid waste are divided into two primary categories the \"dry tomb\"" and the bioreactor landfill. The key difference between these two types resides is the fact that bioreactor landfills require controlled addition of leachate or moisture to the solid waste in the landfill. These types of landfills are considered to be more environmentally friendly. The effective recirculation of a leachate and other liquids or fluids (such as steam or air) to the solid waste in the landfill is a major component in a bioreactor landfill.

In the district of Hagalund in Solna, trucks with a mobile vacuum technology, collect waste and newspapers. The system is not only easy for the residents, it also improves the waste collector's work environment and reduces the operating costs.

At Alsterbro sewage treatment plant, wastewater is purified in three steps.

Two sewage treatment works in Stockholm are producing biogas from sewage sludge. After having purified the gas, it can be used for both heating and vehicle fuel and in addition creates no net emissions of carbon dioxide. Consequently, the treatment works have reduced their amount of emissions and become energy suppliers. Therefore, sewage sludge is no longer an environmental problem, but an important energy resource.
