Abstract

This paper aims to evaluate the reduction on greenhouse gas emissions in rice and wheat and their supply chains by incorporating carbon capture, utilisation, and storage into fertiliser production mainly from ammonia process, which is the section of fertiliser that produces the most carbon dioxide. Greenhouse gas emissions of these grains without carbon capture, utilisation and storage are provided from the results of life cycle assessment in the literatures. After that, a carbon dioxide emission from fertiliser production is quantified. The alternative considered for utilisation is enhanced oil recovery and it is compared with conventional way of oil production. The effect of carbon capture, utilisation, and storage in greenhouse gas reduction are presented in term of rice and wheat’s supply chains to make people conscious about the use and optimisation of food. The reduction of greenhouse gas is around 6-7% in rice supply chain e.g. rice milk, spoons of uncooked rice and 14-16% in wheat supply chain e.g. pasta, one slice of bread. Although the alternative with carbon dioxide storage demonstrates marginally higher greenhouse gas reduction, enhanced oil recovery may offer economic incentive from additional oil production that could reduce the cost of rice and wheat.
