- Description: Abstract: This study was designed to explain current food waste practices, specifically from the perspective of the staff in hotel kitchens. A case study of the perceptions of the staff involved in the food waste chain in a hotel group in Gauteng was undertaken, using a quantitative approach. The study objective was achieved using structured questionnaires that were administered to the relevant stakeholders involved in food waste generation. The findings revealed that the staff concerned generally had a positive perception of the environmental issues pertaining to food waste generation. With this positive foundation, the study recommends that general hotel initiatives should focus on the food waste policies and procedures that capitalise on the positive perceptions involved, by means of assisting staff to create greater balance between their beliefs and work practices. Initiatives such as specific training could assist the staff to better understand ‘best food waste practice’ in relation to such negotiated sustainability issues as “social, environmental and financial policies and procedures”. The study proposes a conceptual framework that could be useful and applicable in the managing of food waste within hotels in the South African context. The study, further, offers insights into the current food waste strategies that are in place to reduce the amount of food waste within hotels and to further unpack the nature and patterns of food waste within specific hotels.

- Description: Abstract: Producing energy from fossil fuels has created unliveable conditions. Climate change for instance, is one of the most environmental issue of our time. Renewable energy, clean source of energy, is considered as an essential part of the remedy. In this study, we investigated the production of biomethane via anaerobic monodigestion of food waste (FW) and co-digestion of FW with cow dung. The digestion took place under thermophilic conditions at 45˚C. A comparative analysis was done on the biogas yield of both mono and co-digestion. FW, FW and cow dung of the ratios, 2:1 and 1:2 were used as the substrates in the digestion. The anaerobic monodigestion of FW displayed the highest biomethane yield produced, of 405.1 Nml. Two main parameters helped in achieving that, volatile solids content (VS) and total solids content (TS). In addition to the two parameters, the pH and the C/N ratio helped in enhancing the biomethane production of both mono and co-digestion. As the objective is the optimization of the biomethane yield by co-digestion, co-digesting FW with cow dung resulted in decreasing considerably the biomethane yield by 32.16 to 33.99%.
