Alteo cares for the environment because it makes good business sense and it’s the right thing to do.
We are committed to continually monitoring and minimising the impact we have on the environment and the communities where we operate.
Access to reliable water supplies is critical to Alteo’s business operations, and we recognise water scarcity and usage concerns. We therefore continuously monitor our water usage to improve our water management and use irrigation systems and water as efficiently as possible, for instance by using treated wastewater for irrigation. Alteo’s operations derive most of their water for agricultural and industrial purposes from riparian water rights in Mauritius, Tanzania and Kenya. We also source water from the public distribution system.
Alteo keeps careful records of how much energy its operations use, where this power is sourced from and how it is produced. We produce energy from sugar by-products during the sugar cropping season in Mauritius and Tanzania to minimise our energy consumption and our dependence on fossil fuels. We constantly seek to increase the proportion of energy that is produced from renewable sources such as bagasse and woody biomass, and are also branching into solar energy.
Alteo collects data about the process chemicals, pesticides, herbicides and fertilisers that it uses in its sugar activities, and which can affect biogeochemical cycles. By measuring our use of these inputs, we can improve how effectively we are using them.
Waste & Emissions Management
Alteo measures and controls its waste and emission outputs. We comply with the regulations that apply in each of the areas that we operate in.
In accordance with Alteo’s wastewater management strategy, we treat our wastewater to a high standard. We constantly strive to measure our operations’ water footprint with greater accuracy and precision.
Our Mauritian sugar, energy and property operations monitor their wastewater outputs and are equipped with wastewater treatment plants. Our Anahita estate’s gardens and golf course are irrigated with treated water. Our industrial sites in Tanzania and Kenya are also equipped with decantation and sedimentation ponds.
Alteo aims to minimise its waste. We reuse the by-products of our sugar activities as follows:
- Bagasse is used for renewable energy production
- Molasses are exported to produce alcohol and renewable fertilisers or are processed into animal feed
- Filter mud is re-injected into our fields and represents a valuable source of nutrients for both the soil and the sugarcane
- Cane trash is used for pest control and weed control and could potentially be a source of renewable energy
- The bottom ashes from bagasse burning are applied to fields as nutrient supplements
Alteo constantly monitors and controls the primary air pollutants emanating from our industrial sites. We comply with the environmental regulations and norms applicable in each of the countries in which we operate.
