CeTeau Biogas

CeTeau Renewable Energy Techniques

are tailor made solutions to create biogas from organic waste. Most processes dealing with organic materials generate organic waste. Left over products from sugarcane, tapioca, and palm industry are typical examples. Also manure from animals or slurries from food industry are organic waste sources. This waste still contains valuable energy. CeTeau offers solutions to make use of this energy.

"Turn need into virtue and generate income from waste products"

Organic waste ferments easily, especially in Asia where the temperatures are very suitable for the bacteria to grow. Fermentation of the waste produces biogas that can be used for power generation.

Biogas consist mainly of Methane and CO2. This gas is after cleaning by a scrubber suitable to drive a gas engine. With the help of an electrical generator energy is created. The scrubber is essential for optimal engine efficiency, increasing lifetime, reducing maintenance costs and cut down of Sulphur dioxide emissions.

The heart of the biogas installation is the digester. The most economic type digester for liquid waste is the so called covered lagoon digester. This is an in-ground pond with a flexible or floating gas tight cover. The organic waste materials are stored inside the covered lagoon and fermentation will take place in the digester. The gasses are collected under the cover and transported via pipes to the gas engine.

"We create quality holding areas of any size with piping systems and associated requirements"

Our geosynthetic products

are excellent for lining and covering. These products have a high tensile strength and are UV resistant, ensuring low maintenance and a long life time.

Each covered lagoon digester has a tailor-made design to fit the available site and type of waste. Our engineers will work out the most suitable layout for each location while environmental engineers will carry out the process design. Specialist equipment such as the scrubber and gas engine are selected in consultation with the customer.

A covered lagoon digester requires a relative small investment. Due to the high output and long technical lifespan a covered lagoon digester is an economic attractive concept. The fermentation is a stable process, which is convenient in operation and maintenance.

We provide a one stop solution for your needs:

  • Lining, covering and piping for waste ponds
  • Modification of existing waste ponds into covered lagoon digesters
  • Design and construct of complete covered lagoon biogas systems

Advantages of covered lagoon digesters:

  • Create valuable biogas from organic waste
  • Reduce odour and CO2 emission by making a closed system
  • Flexible design for any size digester
  • Possibility to use existing waste ponds
  • Long life time and low operating cost
  • Less organic rest waste
