Demonstration of an innovative solution to reduce greenhouse gas emissions in vineyards while improving the soil in arid zones.

Environmental problem

Los restos de poda de vid son considerados un residuo de difícil gestión dada su baja densidad y gran concentración, especialmente en grandes países productores como es el caso de España. Esto unido a la falta de una solución de bajo coste hace que la práctica más extendida para gestionar dichos residuos sea su quema en campo. Esta práctica presenta serios problemas medioambientales como la emisión de GEI (gases de efecto invernadero), el riesgo de incendios forestales o la destrucción de materia orgánica tan necesaria en los suelos de áreas áridas, considerándose un despilfarro de recursos.


LIFE Sarmiento Project, co-financed by the Programm for Environment and Climate Action of the European Union (LIFE), seeks to demonstrate how an innovative low-cost solution for pruned vine shoot management contributes to climate change mitigation and adaptation, by replacing the current practices with more sustainable and beneficial methods.

The proposed solution is based on the enhancement of such residues and their transformation in by-products by improved composting techniques that provide quality compost with added bio-stimulating properties. This compost can be used as an organic amendment, improving the soil and biodiversity status and contributing to the Circular Economy, as well as an alternative substrate to those crops based on peat. The management system anticipates any future administrative restrictions and provides a feasible solution in both economic and environmental terms. Also, it contributes to tackle the cellar wastewater issue through its reuse in the composting phase.

Microgaia Biotech, Eurovértice and "Nuestra Señora de El Rosario" cooperative are involved in this 4-year project (01/09/2016 - 31/12/2020) with a total budget of €835,020 and a LIFE co-financing of €495,365.

Location: The project is developed in the Protected Designation of Origin Bullas (Region of Murcia, Spain).


The purpose of the Project is to reduce any impact on the climate generated by the burning of pruned vine shoots, replacing the current practices with more sustainable and climate-friendly methods.

In particular:

1. Climate change mitigation

Avoid burning of pruned vined shoots (and thus CO2 emissions).

2. Climate change adaptation

Improve soil resilience and biodiversity by new agricultural practices in dry climates.

The Project will also try to achieve other specific objectives:


Collection of pruned vine shoots in farming plots following the annual pruning.

Transfer of pruned vine shoots to collection areas for chipping.

Transfer to the composting site.

Composting process for 6 months.

Transfer of compost to the plots where the pruned shoots were collected.

Application of compost on soil

Review of soil, plants and land performance to check pruned shoot properties as fertiliser and bio-pesticide

Training and communication activities.
