Natural gas for animal feed

Olufola Wusu

Recently, the Nigerian National Petroleum Corporation claimed it would partner a Danish firm, Unibio A/S Limited, in a joint venture operation to produce animal feed that would guarantee a 10 per cent equity financing.

The national oil company, in a statement, said  the proposed joint venture company would be engaged in the production of animal feed from Nigeria’s abundant natural gas resources.

From this action, it would seem that the NNPC is keen on taking the lead in monetising Nigeria’s gas resources by turning some of them into animal feed.


Natural gas is being used to manufacture animal feed. The animal feed pellets are made using methane-eating bacteria; methanotrophs, that are found in soil and lakes. These bacteria are fed methane gas, which makes them grow and multiply into a protein-rich biomass that can be dried and turned into animal feed.  With most fermentation, the carbon source is sugar, here, the source is methane.

Busch-Larsen, the chief executive of Unibio, also working on a methane-based animal feed, was quoted as having said: “It is a difficult reaction to control. You need to get as much methane gas as possible into the liquid that the bacteria are in.” The aim is for the bacteria to reproduce efficiently enough to make the process worthwhile. This technology seems to have reached the point where it can be commercialised.

Unibio aims to sell its product to fish, poultry and pig producers as the protein has been approved for fish and animal use by the European Union, and farmers have so far been enthusiastic about the product.

Global demands for food are expected to increase close to 100 per cent by 2050 driven by an increase in the global population to nine billion, from the current 7.6 billion and a growth in affluence primarily in China, India, Eastern Europe and Latin America.

A recent report in The Sun Newspapers noted that the global animal feed market could be segmented into five divisions based on livestock: poultry, swine, ruminant, aquaculture and others, and the cost of their feeding is on the high side especially the pet animals, which are also known as companion animals.

The major ingredients in animal feed are maize and soybeans. Other raw materials that can be used to produce animal feed include groundnut, sorghum, and cassava and the major ingredients include cereals, fats and oils, which provide the protein and energy required for animals to maintain good health.

Natural gas is used for the manufacture of fertiliser and animal feed. Thus, natural gas plays a critical role in agriculture. The World Health Organisation estimates that Nigeria needs about 1.5 billion litres of milk annually. While the US Department of Agriculture puts Nigeria’s “insufficient” milk import bill at $225 million per year, while estimating that Nigeria’s dairy market is potentially worth $3bn. The president of Dangote Group, Aliko Dangote, plans to own 50,000 cows by 2019, and produce 500 million litres of milk per year. Those 50,000 cows will require a lot of feed which can be made from natural gas, instead of importing feed.

Albertamilk.com states that a lactating cow will consume between 18 and 25 kg of dietary dry matter each day, depending on how much milk she is currently producing! If one cow consumes 25 kg of feed a day, that will be 750kg of feed in a month; the 50,000 cows may consume up to 37,500,000kg of feed in a month! For those who know the average price of a bag of animal feed, you can do the math…

Besides, there will be a further reduction in gas flaring; while companies have one more reason not to flare gas. There are huge possibilities in view of the demands for this kind of feed as it will boost food production in Nigeria tremendously. The benefits are not only in local production and consumption of the feeds but also in terms of revenue generation in foreign currencies through export to various countries.


Production of the protein using natural gas, some water and land, makes it more sustainable than feed such as fishmeal or soybeans. Production of the protein uses up methane, a Greenhouse gas.

In Nigeria, we are importing most, if not all the, raw materials needed to manufacture animal feed, and when the foreign exchange market fluctuates, animal feed becomes more expensive, making it difficult for our farmers to earn a good living without further impacting on our environment.


Thus, natural gas, fed into a fermenter, is the key component used to convert Methylococcus capsulatus into highly concentrated protein pellets. The fermenter is designed to provide the bacteria with optimal growth conditions, including the addition of methane. The bacteria are harvested continuously using a downstream process that removes liquid to increase bacterial biomass. The water is recycled. The final stages of the process turn the biomass into easy-to-digest granules that are 73 per cent protein.

The PUNCH recently reported that the dredging activity going on around Iyana Iworo area of Lagos has driven the fish further out to sea. This leaves even less fish nearby to be processed into animal feed.


It goes without saying that companies in the gas to animal feed industry would probably not have been formed and would not continue to exist today without protection of their Intellectual Property!


For the gas industry to thrive, we need governmental support for our local industry; government has given some support in the National Gas Policy. However, technological growth and development does not happen by chance. In this writer’s opinion, our local companies have a duty to take full advantage of governmental support by actively innovating and commercialising their resulting innovation and Intellectual Property.


Nigeria is placing a huge premium on agriculture; at the same time it is also placing a bet on agriculture, gas to animal feed may very well be the fertiliser that will ensure that both endeavours blossom adequately.

It goes without saying that technological development does not happen by chance, it can be encouraged by good policies like the National Gas Policy serving as a springboard for the inventiveness of our local companies to flourish.
