In the recent past, NEMA has shut down a number of abattoirs around the country. This is mainly as a result of non-compliance with Environment Management and Co-ordination act (1999). The most recent case was in 30 January 2022 when NEMA ordered for the permanent closure of all 15 slaughterhouses in Kiamaiko. The authority wanted them to relocate to the newly built multimillion shilling slaughterhouse in Lucky Summer, Njiru. This was mainly because the slaughterhouses at Kiamaiko were polluting the Nairobi River and the authority wanted to put this to a halt. (S.Wanjiku., 2022) In 2008, NEMA was forced to shut down the Dagoretti abattoirs for a period of around 2 months for non-compliance of their environmental policies as River Kabuthi was being heavily polluted. This forced them to set up a biogas digester as well as anaerobic treatment ponds so as to avoid disposing waste into the river. The slaughterhouse was then reopened after presumably complying with the NEMA standards. Wastewater from the lagoons was then discharged into the public sewer after treatment. The biogas produced electricity to be used by the abattoir as well as the surrounding community. Biogas for cooking eased the financial and social burden of these families and reduce deforestation and land degradation. (Thaiya, 2008) However, the setting up of the biogas plant was done over 10 years ago. There has not been an upgrade of the structure to deal with the ever rising demand for meat in the city. The biogas plant set up at that time was however not efficient as the abattoirs produce more waste than the plant can handle. It is thus not able to deal with the capacity of the slaughterhouse. This simply implies that the standards set out by the National Environmental Management Authority (NEMA) have not been met. After a treatment plant has been set up, routine maintenance should be carried out in order to ensure waste has been efficiently treated.
