Fertilizer project using insects to ramp up production

A project developed in the last three years with insects, to produce fertilizers from vegetable by-products and animal feed flour, envisages an investment of €15 million in the district of Santarém, said one of the promoters.

The plant will allow a scale up of production of organic fertilizer obtained by the action of insects, and its transformation into flour for feeding birds.

The results show that the use of this organic fertilizer has resulted in a 16% increase in potato production and, while the quantity of tomatoes for industry has been maintained, the quality is "substantially better”.

The insect meal, which replaced imported soya flour in the feeding of laying hens, did not change the quality of the eggs produced, demonstrating that "it is possible to produce animals in a more sustainable way".

The unit that should result from the project, to be developed as of next year and expected to come on stream by the end of 2021, "will be one of the top five in the world" and will be "at the cutting edge of technology”.

It will have the capacity to produce 2,500 tons of insect protein and 500 tons of insect oil annually, generating 9,000 tons of organic fertilizer through the conversion of about 36,000 tons of by-products.

EntoValor received community support from Portugal 2020, as part of the circular economy, since it allows the use of vegetable waste, estimated at around 30%, producing natural fertilizers, with benefits for plans and soil (namely greater efficiency in water retention, a critical factor in drought situations).

On the other hand, insects - in this case the larvae of the black soldier fly - give rise to "two alternative sources of nutrition: insect protein and insect oil, which are becoming popular in aquaculture production”.

With the construction of the plant, the use of insect meal, tested at this stage in poultry, will be extended to pigs and fish, said Daniel Murta, stressing the decrease in dependence on international markets and the outlook that is opening up for export.

During the 40 months of the project, four master theses were written, several technical and scientific articles were developed, more than 50 presentations were made in symposiums and congresses and a book was written in collaboration with the General Direction of Agriculture and Veterinary.


The explanation is not very well achieved because only after a few paragraphs it clarifies what the project is all about and eventually identifies the maggots, which grow on organic substrates, and then are processed into flour meal and oil. This is only “new” in Portugal as people, especially in Southeast Asia, have long been producing, marketing and consuming in large scale a wide variety of insects, their larvae and derivatives as animal or human food. Larvae, maggots, grubs, caterpillars or adult grasshoppers, crickets, beetles, cockroaches or whatever else, end up alive, stewed, roasted or fried end up in human stomachs. Now, western nutrition activists have discovered them are making them the new panacea that will meet most animal and human protein needs on a very, very “green” basis!
