KSC Integrated Cane Model Approach for Green Production

-

By: Hassan Mofadel (PhD), R&D Manager, Strategic Planning Department, Kenana Sugar Company, Khartoum, Sudan

 

Background

Kenana areas as a part of Nile Basin are very reach in natural resources, as characterize by completely flat clay soils and virgin lands additionally the rainy season extends to more than three months. Thus the steepness cross the Nile flow is helping in water harvesting. Before and during establishment of Kenana project, people surrounding are staying in traditional and simple houses without any electricity and treated water with a view schools, hospitals and most of the population nomads and lives below the poverty line. The establishment of Kenana project using a unique integrated approach in sugar schemes   creates many occasions in one process by using water for irrigation and factory demand to get sugar and generate steam from bagasse where the steam will be used for factory machines, evaporation processes and electric generation to cover factory demand and domestic uses and also production of ethanol from molasses to be used as a fuel. However, filter mud, vinasse and trashes as by-products of different processes were also being recycled for bio-fertilizer and when it used in the field significantly water and chemical fertilizer use efficiency were increased. The objective of this part therefore, is to highlight KSC experience as integrated cane model approach for maximizing food and energy consumption with a positive contribution to the rural areas in the Nile Basin and global climate change.

 

Methodology Approach Used

The establishing of integrated cane model approach for sugar schemes elsewhere in rural areas started using a complete and details studies and design to cover the requirements of using the recycling water and generation processes for the factories and domestic demand and to insure the maximum water use in irrigation, power generation purposes of energy and ethanol fuel by maximizing complete use of by-product being generated from different processes stages. This integrated cane model approach was adopted from day one in KSC being considered in the first design and implementation phases as well as the expansion, improvement and developmental plans. Due to accumulation of such experience a complete data base with respect to this approach is being build and reflected in all technical services that provided by KSC in the field of sugar industry nationally, regionally and internationally. This cane model approach definitely and will continually position Kenana as global and unique firm in sugar industry.

 

Analysis and Results

The analysis shows that the land by this kind of cane model approach being adopted by KSC was made a big change in the rural area to urban area and provided population with different specialty and wide range of experiences.  Additional to the significant improvement of quality lifestyle to the rural people living in these areas and creation of job opportunities were observed.  Sugarcane is the major and core business in KSC corporate farm other crops and plantations such as forestry, animal farms, and fishing were also being part of the scheme and had a positive change in climate. Figure 7 illustrated clearly the integrated cane model approach that adopted by KSC.  The ultimate results of using such integrated cane model approach for sugar scheme project were:

 

•  Water use efficiency for irrigation and factory processing.

•  Power generation from by-products from cane such as bagasse

•  Production of ethanol fuel from molasses and second ethanol generation from trashes as a cellulosic source

•  Water recycled from the factory to the irrigation processes

•  Water harvesting for supplementary irrigation

•  Animal feed from sugar tops, molasses and bagasse

•  Bio-fertilizers from vinasse, filter mud, trashes and animal manures

•  Using of solar energy for the small and far villages

 

A range of products such as wood, horticultural, animal feed and products (milk, meat, fisheries and poultry) were being produced and distributed in local and international markets. Those also contributed positively in business units revenues. This integrated cane model approach is fulfilling the vision of KSC to be a source of food and clean energy.

 

The most important dimension is the corporate social responsibility (CSR) and positive environmental impact and carbon credit contribution. These will absolutely positioning KSC as green economy Business Company worldwide. As KSC exporting a raw sugar and ethanol to EU markets always subjected to CSR and Ethanol Sustainability auditing performance. Table 6 shows the contribution of KSC in different social dimensions and environmental impact mitigation and compaction as part from climate change phenomena.

Initiatives and Way forwards: KSC to achieve its objective in green economy and to contribute to the clean business production based on the cane model mentioned above the following initiatives were undertaken:
