Abstract: A conceptual network of chicken meat and egg producing and consuming businesses consisting of a chicken farm, a restaurant, a pet food manufacturing plant, a vegetable garden, an olive garden, a grain field and a manure gasifier was assessed in terms of cumulative degree of performance (CDP) and cumulative carbon dioxide emission (CCO2). Five different cases with different resource utilisation preferences were assessed. Case 1 was the base line, where manure was not gasified and chemical fertilisers were used in agriculture. In case 1, CDP and CCO2 were 0.66 and 7,500 kgCO2/year, respectively. As chemical fertilisers were replaced with microbial fertilisers and manure was gasified sustainability improved. In case 5, only microbial fertilisers were used in agriculture and the manure was gasified. The highest CDP, 1.05, and the lowest CCO2, 2,539 kgCO2/year, were obtained in case 5, therefore, it was regarded as the most sustainable case, among the alternatives assessed.

Keywords: sustainable network; cumulative degree of perfection; cumulative carbon dioxide emission; poultry industry.
