Egg producer invests in energy plant technology

Jon Lawson

Weltec Biopower will shortly start building an anaerobic digestion plant for Colombia‘s largest egg producer. The 800kW biogas plant is to go live in early 2017. In terms of the feedstock input, the operator Incubadora Santander, which produces about 3.5 million eggs a day, plans to make use of the co-digestion of dry chicken manure from the laying hens and process water from the production.

Since the Colombian government started supporting the generation of renewable energies, especially the agricultural industry has discovered its huge biomass potential. So far, only little of this potential has been converted into green energy. In view of these framework conditions, the egg producer Incubadora Santander has decided to generate energy from biomass. The enterprise – which operates several poultry farms close to the western Colombian province of Cauca – markets its eggs under the Kikes brand in 14 cities in Colombia.

The production yields a great amount of dry chicken manure and process water, with which the 800kW biogas plant from the German plant manufacturer Weltec Biopower can be operated without purchasing any additional substrate. The feedstock will be pre-treated in a sedimentation tank. There, the manure will be separated from sand and lime and will be pumped into the 4,903m3 digester by way of an upstream storage unit with a capacity of 1,076 m3. Through the co-digestion, the digestate will reach a high fertiliser value, enabling it to be returned into the plant‘s agricultural substance cycle for efficient use as liquid manure on its own fields.

The high quality requirements of South America‘s agricultural and food industry were a key reason why the operator Juan Felipe Montoya Muñoz opted for WELTEC technology “made in Germany“. For the sake of hygiene and other reasons, the company prefers stainless steel, a high-quality material, for the construction of the pre-storage tanks and digesters.

Apart from the high quality and the flexible substrate input, compact delivery and quick assembly are additional advantages of this material. Plant modules such as the ready-for-operation CHP plant, the preinstalled pump and control technology and the stainless-steel panels for the tanks will be transported to the plant location in maritime containers from Germany that will pass the Panama Canal. The 80km waterway cuts the distance from the East Coast to the Pacific Coast by several thousand kilometres. With the Weltec biogas plant that is to supply power and process heat from early 2017, Incubadora Santander will be well prepared for its expansion plans.
