    Abstract : After the sewage wastewater is collected from different households and directed to the treatment plants, it goes through several processes, which are physical, chemical and biological. The different processes remove the contaminant, and produce a semi-solid material named sludge. Sludge has a huge amount of liquid. READ MORE

  2. 2. The weight-based tariff and recycling of cans and PET-bottles : a study of behavioral spillovers in the context of waste sorting and recycling

    University essay from SLU/Dept. of Economics

    Author : Linda Skogström; [2019]
    Keywords : behavioral spillovers; cans; deposit; economics; panel data; PET-bottles; recycling; waste; waste sorting; weight-based tariff;

    Abstract : The aim of this paper is to investigate whether the weight-based tariff, which was introduced in nine municipalities between 2007-2017 to increase waste sorting and collection of household waste for recycling, had a behavioral spillover effect. To estimate the spillover effect, I examine whether the weight-based tariff had an effect on the recycling of cans and PET-bottles in the Swedish deposit recycling system. READ MORE
