Waste management in Kenya’s urban centers is becoming a momentous task considering the country’s desire for a middle income industrial economy. The National Environment Management Authority (NEMA) is concerned with the growing rate of waste generation that does not match the rate of collection. Among the industrial sectors that are poised to play a significant role in realization of the middle income industrial status is the textile sector. However, this is a sector that contributes to high volumes of waste generation in Kenya. Yet, it is envisaged that adoption of waste-sensitive procurement could be the panacea to waste management in the sector. The purpose of this study was therefore to investigate the effect of procurement performance practices on waste management in textile firms in Nairobi City County. This study was grounded on the positivist research paradigm in adopting the ex-post facto research design, to interrogate the direct effects of the three procurement practices on waste management. Cochran’s ample size formula was used to decide on a sample size of 142 employees. Stratified and simple random sampling techniques were used to draw the required sample of employees from the respective textile firms. Data were collected using a structured questionnaire comprising of four sections in line with the four constructs under study. Multiple regressions analyses were run to test the postulations made. The study confirmed that textile firms under investigation were not emphasizing more on waste prevention and minimization when procuring materials. This was deemed to be serious considering that supplierprequalification, invitation to tender, and contract structure were all found to be significant and positive predictors of waste management in the textile firm’s context. The conclusions made from the study findings were that; textile firms in Nairobi City County were facing the challenge of waste management due to their laxity in emphasizing waste-sensitive procurement practices. The firms however stand to gain by leveraging upon supplier pre-qualification, invitation of bids, and contract structure that are centric to waste generation. The findings of this study contribute to the theory and practice of waste management by showing that, waste is best managed at the procurement stage. This therefore implies that textile and waste management stakeholders have the onus of coming up with waste management parameters which, supplier pre-qualification, invitation to tender, and contract structure processes should aim at. Future studies should take into account other procurement practices that can be engaged to prevent and minimize waste. Moreover, there may be need to expand the geographical scope of the firms in order to boost external validity
