DEKKER BIO THINKING understands that liquid waste and polluted soil are not waste but a resource. It sees the need to change the linear dead-end ‘dispose of waste’-economy to the circular economy of contaminated water and soil recovery wherever we get a chance to apply industrial environmental pollution control. It also applies the principle that micro-organisms are the most effective, cost-efficient method of degrading waste products in the environment without costly chemicals or infrastructure.

'CIRCULARITY’ aims to do away with waste while recovering resources for its continual use. At its very core, it encourages the use of eco friendly and regenerative methods with the result of a ‘take, create and reuse’-model of production. READ MORE... - Core Concepts of waste management.

Bioremediation is the engineered application of biological ‘agents’ (including bacteria, algae, fungi, etc.) to degrade a material.

PRINCIPLES: It uses the principles of nature’s biodegradation process and therefore with less disruption of the contaminated environment when compared to other clean up methods. In other words, by using bioremediation methods for liquid waste management and soil pollution control, we use the Earth’s own ‘wisdom’ to conserve it but with the application of environmental-friendly ‘optimized circumstances’, resulting in much quicker results.

With the frequency and complexity of today’s industrial waste streams, Bioremediation’s intelligent biodegradation formulas are critical. The good news is that it cost less compared to other clean up methods, while it also complies with the Department of Water and Sanitation' (DWS) regulations.

On the international front, anti-ecological behavior is strongly discouraged and South Africa’s legislative climate is transforming to embrace the global move towards a decarbonized economy. The year 2019 marked this shift firstly with the implementation of carbon taxes and secondly, the massive shift in South Africa's waste legislation that forbids liquid waste from landfill.
