LeAF is an independent knowledge centre on the development and implementation of sustainable environmental protection technologies that can be applied on a local scale, with the objective of recovering valuable resources from waste and wastewater. These technologies contribute to the realization of Millennium Development Goal no. 7, reducing the number of people without access to safe drinking water and suitable sanitation.
If you tick two options within one filter parameter, then this is treated as an "or" search, meaning either of them could be true. But if you tick two filters for two different parameters then this is treated as an "and" search, i.e. both parameters must be true to return a result. If anything is unclear about how the filter and search combinations work, just contact us: email@example.com
You can run the country filter for the projects by clicking on “Select countries”. However, if you want to combine the country filter with another filter parameter, then you need to operate the “apply filter” button twice: You need to firstly filter by country, then secondly filter by the other filter parameter(s) (or vice versa). To run the filter you need to click on the “apply filter” button.
