The 2-IV National Energy Plan (PNE)
Business Plan 3-National Electrical Planning Center (pden)
PND PNE and pden on Axis II Productive Policy, National Energy Plan and Business Plan of the National Center for Electrical Planning within the Productive Sector, arises in the strategic action 6, the promotion and incorporation of production practices that allow the use rational and conservation of natural resources, enhance proposing the use of biofuels and renewable energy through sustainable use of the capabilities and resources of agriculture.

1 Beneficiaries and stakeholders

a) Beneficiaries
FINCA SA SERMIDE Because with the technology involved is meeting not only with the rules and regulations set by the Ministry of Health for the treatment of waste, but also perceived economic to generate electricity for their own use benefits as well as the production of organic fertilizer.
Also, the surrounding communities by improving environmental quality indices benefit.
The Management Unit Reventazón River Basin (UMCRE) is benefited by this project to be a reduction in the rates of environmental quality in the basin.
Similarly is benefited the Energy Sector, as is reducing energy demand such initiatives.

b) Stakeholders
This project was developed by the AEA, FINCA COMCURE SERMIDE And that is a body formed by Act No. 8023 and consists of the following institutions:
• The Ministry of Environment and Energy (MINAE)
• The Ministry of Agriculture and Livestock (MAG)
• The Instituto Costarricense de Electricidad (ICE).
• The Costa Rican Institute of Aqueducts and Sewers (AyA)
• The National Emergency Commission
• The Technological Institute of Costa Rica (RERI)
• The Federation of Municipalities of Carthage.
• Associations users, such as environmentalists, farmers and industry.

2 Regulation and results

The Ministry of Health issued Regulation No. 32312 of Swine Farms-S to meet the established Articles 331 and 336 of the General Health Law. These rules provide that the pig farms must have adequate system for the treatment of waste (liquid and solid) and in this way prevent or reduce pollution of air, soil or water where possible.
So that in order to continue activities which are compatible with the environment, we have generated a series of technological innovations for the treatment and utilization of pig manure, based on that they are stabilized from biological treatments are these aerobic and anaerobic. One such alternative is the use of the biodigesters (anaerobic system) to generate electricity.
Such resource comes directly contribute in reducing fossil fuel imports, promote local energy solutions and reduce costs on the farm. In addition to a decrease in air pollutant emissions, clean energy production and decreasing the potential encumbrances on ecosystems and therefore biodiversity.
85% biochemical oxygen demand (BOD) with - Yet another by-product known as bio-fertilizer or effluent liquid consistency and nutritional content, which can replace the use of synthetic fertilizers also reduces up to 80 is obtained the costs which are also avoided in respect of discharges of pollutants into bodies of water and meet the requirements dictated by the Ministry of Health.

f) Results
2.1 Use of biogas for electricity generation.
2.2 Improving environmental indicators such as chemical oxygen demand (COD), biological oxygen demand (BOD) and total suspended solids (TSS).
2.3 Use of the effluent as a biofertilizer.
2.4 Conduct project visits with groups of pig farmers, technicians, students and state institutions (MAG - MS - MINAE)
2.5 Reduction of potential encumbrances on ecosystems and therefore biodiversity thus ensuring that Sermide Finca SA meets all standards issued by the Costa Rican development of their work-out in harmony with the environment authorities.
