5.5.1 Waste Management

The laying poultry community is subject to specific regulations to reduce their environmental impact. Among others, there are rules to reduce emissions to the environment and properly manage waste byproducts

  • In Spain, the poultry sector has significantly less impact on the generation of greenhouse gases than other agri sectors. It contributes only 0.14% of emissions of greenhouse gases.  In the past 20 years, through innovation in the Spanish sector and increased efficiency in production, have reduced emissions of greenhouse gases by 4.34% and water consumption per kg 3.50% egg.
  • In the EU, farms apply measures to adjust the diet of hens to their nutritional needs at every stage of life, to improve digestibility and to maximize the nutrients. Thus reducing their environmental impact.
  • Chicken (hen, layers) droppings are commonly used as high quality organic fertilizer for their contribution of nutrients and organic matter. The EU has great need of soil organic matter, organic fertilizers and improve its texture and agronomic quality
  • Minimal handling and packaging made of recyclable materials ensure the sector has a very low carbon footprint.

Liquid effluent is generated by shed washout, equipment cleaning and egg washing. It needs to be properly treated and stored to minimise the environmental threat. The most appropriate design for an effluent treatment system for a farm will depend upon:

  • Size of the operation.
  • Effluent characteristics.
  • Volume of effluent.
  • Proposed end use of by-products.
  • Availability and properties of land for by-product utilisation.
  • Groundwater vulnerability.
  • Sensitivity of neighbouring environment
  • Climatic factors.
  • Topography.
  • Soil characteristics.
  • Reliability and maintenance requirements.
  • Future expansion plans.
  • Regulatory requirements
  • And of course COST
