The reuse of pig slurry as high-quality fertilizer

Ecodíptera project showcases an innovative solution for a real problem

The European Life project “Ecodíptera” has been presented this week in Brussels by its consortium partners. This initiative involves a sustainable and innovative solution for pig manure. The technology applied within the project enables the use of fly larvae to transform pig slurry into a high-quality fertilizer and proteins.

The main idea of “Ecodíptera” is to showcase the viable use of the natural degradation process of animal organic matter in order to obtain the decomposition of pig slurry at an industrial scale.

The material process lies in the controlled use of the fly larvae capacity to grow in organic matter in decomposition. Adult flies, after a phase of feeding and maturation, lay eggs on different types of waste. After a phase of growth, the larva transforms itself into a pupa, remaining still until its birth as a fly. During this process, between 50 and 70 per cent of waste is degraded, being incorporated to the biomass of the larva. However, the rest of the waste is also modified into a high quality organic fertilizer by the secretion and fermentation that takes place after the larvarian action.

The Valencian Region, leader in receiving LIFE EU funds

The seminar, which has taken place at the Committee of the Regions, has been led by the Valencian Regional Minister of Agriculture, Mr Juan Cotino, who has explained that the Valencian Regional government always supports projects that look for innovative solutions for agricultural problems in the region. “This projects is very positive to solve one of the worst problems that farmers have in our region, and in the European Union”, Mr Cotino has stressed. He has also emphasized the fact that, with this project, the Valencian Region keeps on being the EU leader region in receiving LIFE funds.

“Ecodiptera” is a three-year project co-financed by the European Union. With a budget over 1.5 million euros, it has been launched by six partners, under the leadership of the County Council of Valencia. The Fundación Comunidad Valenciana – Región Europea and the consulty agency network of Valencian Municipalities towards Sustainability “Ambienta” are the partners undertaking the communication and dissemination tasks of the programme at a local, regional, national and international level.

The rest of the partners - the University of Alicante, the Slovak Academy of Sciences and the University of Helsinky- are in charge of developing the necessary bases for the building of the pilot plant for the bio-degradation of pig manures, which will be located in Tuéjar, in the Region of Los Serranos, in Valencia.

The project is part of the European Programme LIFE Environment, launched in 1992, and contributes to the implementation, development and enhancement of the environment policy of the European Union.

Im Focus: Climate study finds evidence of global shift in the 1980s

Planet Earth experienced a global climate shift in the late 1980s on an unprecedented scale, fuelled by anthropogenic warming and a volcanic eruption, according to new research published this week.

Scientists say that a major step change, or ‘regime shift’, in the Earth’s biophysical systems, from the upper atmosphere to the depths of the ocean and from...

Im Focus: Lactate for Brain Energy

Nerve cells cover their high energy demand with glucose and lactate. Scientists of the University of Zurich now provide new support for this. They show for the first time in the intact mouse brain evidence for an exchange of lactate between different brain cells. With this study they were able to confirm a 20-year old hypothesis.

In comparison to other organs, the human brain has the highest energy requirements. The supply of energy for nerve cells and the particular role of lactic acid...

Im Focus: Laser process simulation available as app for first time

In laser material processing, the simulation of processes has made great strides over the past few years. Today, the software can predict relatively well what will happen on the workpiece. Unfortunately, it is also highly complex and requires a lot of computing time. Thanks to clever simplification, experts from Fraunhofer ILT are now able to offer the first-ever simulation software that calculates processes in real time and also runs on tablet computers and smartphones. The fast software enables users to do without expensive experiments and to find optimum process parameters even more effectively.

Before now, the reliable simulation of laser processes was a job for experts. Armed with sophisticated software packages and after many hours on computer...
