Commitment to protect the environment -BioTerra

BioTerra is an industrial compost plant that has the capacity to recycle 3,000 tons of organic waste per month.  We are strongly committed to process and dispose organic waste properly in order to protect the environment in accordance to national (DINAMA) and international organizations.  We look everyday to implement new technologies which create value out of waste, and to improve our operations with the aim to offer high quality products for agricultural purposes.


Thanks to local industries and farmers that dispose of organic waste in BioTerra, 15,000 tons of waste is being recycled and disposed of properly.  The result: greater soil conservation, and protection of Uruguay’s ground water, rivers and ocean.

In turn, BioTerra transforms these organic wastes into a high quality fertilizer amendment (compost) which farmers can use to cultivate their crops, and gain harvests of great abundance and greater nutritional value.  In comparison to chemical fertilizers, created only in the 20th century, utilizing compost improves soil quality and fertility for future generations.  A healthy soil offers to the plants that grow in it, the ability to prosper and are less likely to be susceptible to plagues and diseases, therefore minimizing the desire/need to apply insecticides, fungicides and herbicides.  The result: improved environmental conservation, and healthier crops feeding people, making them in turn healthier.

In addition, the BioTerra’s compost production process is strictly aerobic, and therefore reduces greenhouse gases (GEI).  The result: carbon is trapped in the compost to feed microorganisms and plants, instead of being released into the atmosphere and contributing to climate change.


To produce its compost, BioTerra’s a technique called “Actively Aerated Windrow Composting” in accordance to US and European regulations.  BioTerra’s Compost Premium is certified internationally by the Organic Materials Review Institute (OMRI), ensuring it’s high quality and permitting it’s use  in organic agriculture.  During BioTerra’s composting process, materials of plant & animal origin are transformed into high quality compost within 6 to 8 weeks.

Over the years, Bioterra became known internationally as a specialist in composting, building several plants in Argentina and Paraguay, with capacities to process up to 1000 tons per day of waste. What differentiates Bioterra from other compost plants is it’s goal to produce high quality Compost – creating a standard in which producers can rely.  BioTerra’s strict quality controls and experience specially selecting & distributing adequate proportions of raw materials allows it to produce top quality compost capable of producing great agronomic results.  Raw materials include, discarded fruits & vegetables, tree & pasture cuttings, waste from fish, and manures. The diversity of raw materials used is important in order to stimulate a great quantity and diversity of beneficial microorganisms, essential for the formation of humus and other substances that keep the pathogenic microorganisms controlled.

The analyses specifically used in BioTerra to ensure the production of HIGH QUALITY COMPOST are: pH (actual & potential), nitrites, nitrates, ammonium, microbiological respiration index, temperature, conductivity, sulfites, Humus Formation Index, and microbiological count.

The composting process BioTerra utilizes is more complex and has stricter quality controls in comparison to other composting plants/methodologies found in Uruguay. However, BioTerra’s compost is among the best qualities that can be seen in other industrial plants Of the world and qualifies in the best categories according to different international regulations of compost and organic amendments.


“Compost” is an organic fertilizer made from controlled decomposition of organic matter.  Producing compost under aerobic conditions (in the presence of sufficient oxygen) is key to ensuring it’s quality for agronomical purposes, as anaerobic conditions produce undesirable and toxic compounds for plant growth. A correct balance between the initial raw materials, together with the correct humidity and oxygen, causes an increase in temperature and growth rate of the present microorganisms (mostly fungi, bacteria and actinomyces). Each of the strains will have different degree of importance and activity in the process, depending on the stage in which it is found.

The following series of stages are necessary to ensure the proper production of a quality compost:

Fases de Compost BioTerra

Mesófila Phase: During this phase, the rapid multiplication of microorganisms begins to degrade the simplest materials of the transforming mixture in carbon dioxide and heat.

Thermophilic Phase: Microorganism activity releases heat, increasing temperature, and as a consequence the compost pile is pasteurized and any present seeds found in the pile are inactivated. Pathogenic microorganisms possibly existing in the initial raw materials also begin to die during this important phase.

Cooling and Maturation Phases: During this phase, the materials decomposed by the microorganisms during the previos stages, are recomposed and adhered in the phase “humic” which begins to develop slowly on the clay materials and colloidal of the initial mixture, through aerobic microorganisms mesophiles. To maximize the microbiological quality and thus the outcome of the final product, it is important that the previous phases occurred correctly to ensure the existance to the most sensitive microorganisms responsible for the beneficial substances resulting from the Cooling and Maturation Phase.  After a few weeks, the changes in temperature, respiration, and characteristics of the compost pile become very noticeable.

The purpose of the process is to transform the largest amount of initial organic matter into humus of nutrition, under strict control and monitoring of parameters that ensure a directed mechanism of microbiological activity.

Thanks to BioTerra’s strict production processes, it’s compost holds nutrients in stable state (adhered to ionic Exchange sites present in the humus), a low content of salts (low electrical conductivity), does not contain phytotoxic substances (they are generated in Conditions of lack of oxygen or excess water), and a great quantity and diversity of beneficial microorganisms. It has a dark color and a pleasant earthy odor due to the presence of a compound called “geosmin” produced by beneficial species of actinomyces.

Due to the microbiological nature of the majority of BioTerra’s products, we must utilize plastic packaging to distribute our products. Therefore, we select our packaging for it’s capacity to be recycling and it’s durability, and whenever possible we work with local packaging suppliers.  We also encourage farmers to accept compost delivered directly by truck, avoiding the use of packaging all together.  Finally, we are also members of  Campo Limpio, a project dedicated to recycling of plastic containers, further ensuring that our packaging is deposed of properly in protection of the environment.
