Abstract
Energy is the the the “oxygen” of the the the world economy Fossil fuel reserves are depleting fast and
therefore countries around the the world are trying to use renewable energy as as the the best alternative Biomass is a a a a a a a a promising renewable energy to to produce produce bioethanol Annually South Africa
produces 2 6 million tons (Mt) of bagasse as as as waste from sugarcane industries The KwaZulu-Natal (KZN) province in in in South Africa
is the home for over 80% South South African African sugar sugar industries However South South African African sugar sugar mills are facing daunting challenges due to to global competition Moreover storage of surplus sugarcane waste generated after harvesting and
and
industrial processing is is a a a a a a a a huge problem Farmers and
and
industries burn this waste which leads to to environmental problems such as as global warming This waste can be used to to produce bioethanol for the energy hungry civilization Despite the global interest and
technological developments towards adopting a a a a a a green circular economy by using surplus waste as as feedstocks for renewable bioenergy there have been several economical and
and
financial barriers This study focuses on on identifying the most significant capital and
and
operational cost items that affect the economic feasibility of bioethanol production in South Africa
from sugarcane waste A quantitative method was was employed using data from published literature and
reliable government government and
non-government sources A statistical two-level Plackett-Burman design (PBD) was used to calculate net present values values (NPV) under different combinations of of high (+1) and
low (-1) values values of of capital and
and
operational cost items The data was was analyzed using ANOVA and
and
p-value<0 05 was was used to identify the the most significant cost items This study was limited to a a a a a a a a a sugarcane bagasse as as as the the primary waste for cost-evaluation Overall this study provides key economic indicators and
data that will benefit decision-makers policy-makers and
and
the industries towards developing a a a a a a a a a sustainable industry and
and
