Talk to us today to learn more!


With over 15 years of research and development, we have one of the most efficient biogas systems in the world. 



These are large scale systems built according to clients energy needs. They are best applicable for schools, hotels, churches, childrens homes and any other institutions with high energy demand.


These are systems designed for lower energy demands for daily use. They can install in as few as 3 hours producing gas in as little as 3-5 days and run on any biodegradable material with no need for a cow.


The BioSans Gas toilet provides a clean hygienic solution whilst producing biogas and a rich fertilizer bioslurry. They are prefabricated and will be assembled on site in a few minutes.


The output bio-slurry is a mineral rich organic fertilizer that is ready for use and also works as an extreme effective pest repellent.


In order to to effectively utilize all the biogas produced, we have developed other products such as biogas dryers, biogas brooders and more.


As we grow, we are continuously innovating new methods and products that are better, more efficient and simpler to use.
