Natural Capital considers all the natural resources used to deliver our products and services, such as raw materials, water, energy and environmental management components.

Materials Management

Omnicane highly believes in the principles of circular economy, i.e., the rational management and value addition of raw materials entering our different business operations. Our renewable direct materials include sugarcane used in our sugar factory, raw sugar used in our refinery, bagasse used in our power plants, molasses used in our bioethanol distillery, and water used in our different process operations. Non-renewable input materials refer mainly to imported coal, which is used within our power plants as well as transportation fuel used in our logistics operations. The Integration Chart describes the flow of materials at the La Baraque cluster.

Co-ProductsSome 821 tonnes of scum (2017: 1,267 tonnes) were produced by our sugar factory and distributed to small planters in the region for application as bio-fertiliser. On the energy side, some 100,717 tonnes of coal and bagasse ash (2017: 95,159 tonnes) were produced by our power plants.

Energy Management

Omnicane recognises that developing a sound energy management strategy involves the smart use of renewable and non-renewable energy resources in our business operations. Our sugar factory was successfully certified to the ISO 50001 Energy Management System in 2019 while our sugar refinery continued to achieve energy savings through improved process re-engineering. Furthermore, with the coming into operation of our Carbon Burn-Out unit in 2018, we produced 1,561 MWh of electricity from the combustion of coal ashes recovered from our power plants for internal consumption. An analysis of our direct energy consumed from renewable and non-renewable sources demonstrates the following results:

103-1 103-2 103-3 302-1

Energy Efficiency

We put much emphasis on demand-side management and energy efficiency in our operations. For instance, our investments in energy-efficient equipment in the last few years have continued to bear fruit and we have achieved energy savings mainly in our sugar factory. However, the specific energy consumption for the refinery has increased due to reduced operations in 2018.

Non-renewable indirect materials include pesticides, herbicides, chemical fertilisers and industrial chemicals used in our operations and these totalled 2,692 tonnes and 31,005 litres in 2018 (2017: 2,588 tonnes and 32,330 litres). It should be noted that following the implementation of the Bonsucro Production Standard, less herbicides were used in the fields.

301-1

Renewable indirect materials consist of Concentrated Molasses Solids (CMS) and carbon dioxide. In 2018, 90,351 tonnes of renewable indirect materials (2017: 57,364 tonnes) were supplied.

Water Management

Water is an essential strategic resource for Omnicane’s operations. In 2018, the total surface water used was 4,666,768 m3 (2017: 5,587,198 m3) whereas the total amount of groundwater abstracted was 2,920,189 m3 (2017: 3,469,429 m3). As far as tap water consumption is concerned, this amounted to a total of 57,564 m3 in 2018 (2017: 55,532 m3). Overall, the Group’s water consumption has decreased by about 16.1% due to the following: strict monitoring in our sugar factory leading to reduced wastage, lower production levels in the refinery and La Baraque power plant. It should be noted that excess process water from milling operations and the distillery during harvest time is available for reuse in the irrigation of sugarcane fields. Moreover, we do not operate in water-stressed regions and our water usage does not compete with sources of domestic water supply. It should be noted that abstracted ground water is used in our agricultural operations for irrigation purposes.

Biodiversity Management

We are committed to the preservation and enhancement of biodiversity. Environmental impact assessments have concluded that our industrial operations at La Baraque and St Aubin are neither in nor adjacent to protected areas or areas of high biodiversity value. As far as the Mon Trésor Smart City project is concerned, ecologically sensitive or high biodiversity areas have been identified and appropriate measures will be taken to protect and enhance their value.

Emissions Management

Our power plants are equipped with Electrostatic Precipitators (ESPs) for flue gas treatment. Furthermore, ambient air quality monitoring and stack monitoring exercises at our power plants are carried out independently on a quarterly basis by the Air Pollution Monitoring Unit of the Mauritius Cane Industry Authority. Reports demonstrate that all parameters measured are compliant with the EPA 1998 Standards.

Effluent and Waste Management

The commitment for our waste management programme emerges from the Group Environmental Policy and the ‘zero waste’ approach, which places strong emphasis on the 3Rs (Reduce, Reuse and Recycle) principle. The table below shows the effluent generation and disposal in terms of volumes and destinations. It should be highlighted that the volume of water discharged from refinery operations decreased considerably by 92% due to process re-engineering. The volume of clean water discharged by La Baraque sugar factory increased by 23% due to a rise in storm water run-off as a result of heavy rainfall.

GHG Emissions

In 2018, our 90 MW and 35 MW power plants emitted on average 1.25 tonnes of CO2/ MWh of electricity produced from coal, which represents a total of 782,471 tonnes of CO2 (2017: 900,431 tonnes) released. Also, our bioethanol distillery captured and delivered 3,082 tonnes of carbon dioxide to Gaz Carbonique Ltd for use in the beverages industry. However, with the implementation of our Carbon Burn-Out unit, we will avoid the emission of around 29,000 tonnes of carbon dioxide (through the avoided production and import of Portland cement). In addition, the use of bagasse as fuel, contributed to avoiding the emission of around 100,229 tonnes of CO2e in 2018, which helped us mitigate GHG emissions and reduce our impact on climate change.

Solid Waste

The implementation of solid waste management practices within all Omnicane entities is under way. Recycling opportunities for paper waste, old batteries and green waste are also being provided across the Group. The Sustainability Department, in collaboration with Mission Verte, is conducting awareness sessions on reducing waste across Omnicane entities.

Environmental Impacts of Products and Services

Environmental Impact Assessments (EIAs) are carried out prior to any major undertaking being implemented and so far, all our major operations have successfully obtained an EIA licence from the Ministry of Environment. With respect to our Smart City development, two EIA reports have already been submitted to the relevant authorities and we hope to receive our EIA licences shortly. Quarterly environmental monitoring reports, containing environmental performance indicators and mitigation activities are regularly sent to the Ministry of Environment for follow-up as per the terms of the EIA and Industrial Waste Audit guidelines.

Environmental Compliance

The Group Environmental Policy strongly sets the commitment to abide by all local and international environmental laws and regulations relating to business operations. Furthermore, our two power plants at La Baraque and St Aubin are successfully certified according to ISO 14001:2015 Environmental Management System, which enables them to better track their environmental aspects including legislation. In 2018, the Company received no fines or sanctions related to non-compliance with applicable environmental laws and regulations.

Environmental Costs and Communication

Environmental protection has a cost associated with it, which must not be neglected when analysing costs of business operations. Usually, as per customary financial accounts, these environmental costs remain hidden within broad categories of operational overheads and expenses. Knowledge of these costs enables us to not only manage them but also to redesign the production process and reduce the pollutants being released into the environment in the future. We have strived to classify these costs into eight main categories, which pertain to our operations that have the highest environmental costs, i.e. thermal energy, bioethanol and milling operations. It should be noted that environment-related expenses represent around 0.9% of the total operating expenses for the Group in 2018.
