]]>Mavitec’s gasifier converts various kinds of manure and other biosolids into renewable energy and EcoChar, the end-product of the gasification process. Gasification ensures a smaller environmental carbon footprint and will be one of the answers to future energy needs.
Gasification offers a lot of advantages such as volume reduction, production of renewable energy and reduction of CO2, a new way of solving manure issues! The produced heat can be used as energy or hot air and the valuable by-product EcoChar is a powerful soil improver. EcoChar still contains the mineral ash and fixed carbon which offers great environmental advantages and economic value. EcoChar consists of 45% Carbon and the mineral content is high in P, K, Ca and Mg values. EcoChar improves soil fertility, lowers the amount of nutrients needed and reduces your carbon footprint. Applying EcoChar in desert soil retains the water, keeping the soil fertile. It enables sustainable agriculture and at the same time the manure problem is solved.

A large food producer that is fully vertical integrated from cattle to supermarket, has chosen Mavitec Environmental to solve his manure problem as well as soil fertility problem. The customer was not allowed to use fossil water for soil irrigation to feed his cattle anymore. As the desert is facing two major problems – dry soils and fossil water scarcity – the so-called center pivots irrigation fields, round circles of fertile soils to cultivate grain and other crops to feed his cattle, were forbidden by government. To make these grounds fertile the manure from his cattle and water were used. The combination of dry soil and slow water supply leads to water scarcity, so the use of water was no longer allowed from government. The result: a manure surplus and animal feed had to be imported from other countries.
Mavitec developed an innovative technology that converts various kinds of manure into green energy and EcoChar, a valuable by-product of the gasification process. Gasification ensures a smaller environmental carbon footprint and will be one of the answers to future energy needs. Gasification is a new way of solving manure issues and offers advantages such as volume reduction, production of renewable energy and reduction of CO2. The produced heat can be used as energy or hot air and the valuable by-product EcoChar is an amazing product that can be used as soil improver. It still contains the mineral ash and fixed carbon which offers great environmental advantages and economic value. EcoChar consists of 45% Carbon and the mineral content is high in P, K, Ca and Mg values. Moreover EcoChar is dry, free from pathogens and can retain more water than its own weight. It improves soil fertility, lowers the amount of nutrients needed and reduces your carbon footprint.
Circular agriculture
Four gasifiers can convert over 400 tons of chicken manure per day and the daily production of EcoChar is 50 tons.
Applying EcoChar in desert soil retains the water keeping the soil fertile. It enables sustainable agriculture and at the same time the manure problem is solved.
The complete installation is designed, built, and installed by Mavitec Environmental and consists of four gasifiers and two dryers.
]]>The market for growing media is developing rapidly worldwide. European potting soil companies are leading in both quality and cultivation knowledge. In order to build on this advantage, it is necessary that more peat substitutes come onto the market. Available alternatives are coconut products, wood products, fiber products such as grass and hemp and local organic waste streams. Without processing Dutch organic residual streams are usually unsuitable as a root medium, due to a too high salt load, too high acidity, light growth inhibiting substances and too low stability.
In the PPP Circular Growth Media nine parties have joined forces. By deploying their processing techniques together, it is possible to produce new fibre products and organic residual products of high quality. The Dutch market for growing media (4 million m3/year) is extensive and requires multiple solutions. That is why PPP includes four companies whose core business is the collection and processing of organic waste. Each company will focuss on different organic waste products and different markets.
The approach involves washing out and neutralizing compost and wood fiber by Attero. Stabilizing organic residues into low-salt biochar by Den Ouden and nutrient-rich EcoChar by Mavitec Environmental for outdoor cultivation. Binding of plant fibers into shape-retaining growing media is done by Terrafibre. The participating potting soil companies (Jiffy, BvB-Kekkilä and Pokon Naturado), will create optimal mixes of these products and offer them along with instructions to growers and consumers. The research companies Wageningen University & Research, business unit greenhouse horticulture, and TNO investigate specific questions. It suits the leading position of European potting soil companies that only qualitatively distinctive products are made.
For cultivation companies in greenhouse horticulture, a successful product means a more socially acceptable product. For arable farms, the use of stabilized organic matter means that the organic matter content of the soil is increased. As biochar is so stable, this counts as negative emissions of carbon dioxide. With these possibilities, the greenhouse horticulture sector contributes in various ways to social expectations and a more circular economy.
Mavitec Environmental’s EcoChar
Mavitec Group is specialized in creating high quality recycling systems. Mavitec finds and maximizes value from organic by-products, based on the commitment to taking by-products from one process and recycling them into valuable materials. Mavitec is one of the leaders in the rendering industry and also developed an innovative gasification system that converts various kinds of manure into green energy and high value EcoChar, the solid output of the gasification process. Gasification is an environmentally friendly technology in which pre-dried manure is heated in an oxygen-poor environment. The energy produced can be reused and at the end of this process EcoChar is created, a fertile soil improver in which all the valuable nutrients of the manure are preserved. EcoChar consists of high P and K (Mg or Ca) values, it can hold more than its own weight of water, is pathogen-free, dry and can be easily transported. Besides, EcoChar has a carbon-negative process Co2:C ratio (3:1). Because of these characteristics EcoChar will greatly improve soil fertility, lowers the amount of nutrients or fertilizer needed and reduce your carbon footprint. With is innovative gasification system Mavitec Environmental offers a smart and sustainable solution to the global manure problem and answer to the growing demand for fertile soils.
The four-year project is launched in June 2021.
