a) Environmental Dimension The causal loop diagram (CLD) for the sustainable environmental practices are shown in figure 2 on the following page. The model demonstrated the challenges faced by organisations in order to achieve a sustainable environmental performance. The production of food products is intensified due to increase in product demand, which consequently, increase the inputs of raw materials, chemicals, water and energy denoted by plus (+) sign. Moreover, there is increase of outputs such as solid waste, wastewater, GHG emissions, finished products and transportation denoted by plus (+) sign. However, more solid waste would increase dumping to landfill as well as wastewater to sewage. Wastewater treatment could reduce the amount of wastewater discharged as sewage. Thus, reduction in utility bills of organisations. However, production intensity would causes production cost to increase and consequently, decreasing the environmental performance. Transportation also causes increase in GHG emissions. Production cost can be reduced by increasing machine efficiency, through good operations practices and human resources productivity. Moreover, the practice of eco-design during product development enable to reduce consumption of raw materials, chemicals, water and energy. Sensitisation campaigns on sustainable consumption and production could increase development of green products. The use of renewable energy can also reduce dependence on fossils energy. Additionally, maintenance practices increase the machinery efficiency in order to decrease the production cost. Revenues and profits of organisations are increased because of more customers and finished products. The decrease of production cost would increase the competitiveness of prices.
