Biogas Supplemented Agriculture Tubewells

In view of prevailing energy crisis in Pakistan, the Chief Minister constituted a Cabinet Committee on Energy (CCE) under the chairmanship of Minister for Energy to make recommendations and prepare viable plans to mitigate the energy crisis. The Committee held series of meetings with experts, private sector and other stakeholders and deliberated on exploiting indigenous potential energy resources. The Committee also recommended for utilizing biogas energy for diesel tube-wells while focusing on small and medium farmers, in addition to other projects identified.

During one of the meetings of the Energy Council held on October 10, 2013, the Chief Minister approved the plan for installing biogas tubewells. It was also decided that the biogas plants would be installed and connected with tubewells by pre-qualified firms on turnkey basis. The Government shall provide subsidy for the installation of biogas plants @ Rs.100,000 to the farmers having land up to 5 acre, Rs.75,000 for farmers having more than 5 acres and up to 12.5 acres, and Rs. 50,000 for farmers having more than 12.5 acres and up to 25 acres. A international consultant would also be hired for the planning, supervision and execution of project activities.

Objectives

  • Promote the use of biogas energy for operation of 20,000 agriculture tube-wells owned by small farmers by providing financial incentives (subsidy)
  • Minimize the energy cost of tubewells @ 70%-80% per hour and;
  • Enhance agricultural productivity through timely availability of irrigation water and use of biogas manure rich in nutrients.

The proposed project will help reduce the energy cost of agriculture tubewells and improve profitability of small and medium farms, hence poverty alleviation of farmers. The project would also create good impact on crop productivity by conversion of animal dung into high value organic fertilizer (“biogas slurry”).

Introduction to Biogas Energy

Biogas is produced by the breakdown of organic waste by bacteria without oxygen (anaerobic digestion. Generally animal dung, crops residue, poultry droppings are used for biogas generation. Biogas contains Methane (CH4) 60-70%, Carbon dioxide (CO2) 30%, Nitrogen (N2) 1%, Carbon Mono Oxide (CO)and Hydrogen Sulphide (H2S) in traces. It is non-poisonous, have no offensive smell, can easily burn with air when mixed @ 6.25%, checks de-afforestation, is cheap and environmental friendly.

The biogas manure/ slurry is produced through fermentation process which is enriched in Nitrogen (N), Phosphorous (P), and Potash (K) compared with fresh manure / fertilizers. It is used as organic manure to improve soil health and enhance crop production leading to reduced consumption of mineral fertilizers. Experiments have shown incremental crop yield (10-20%) with biogas manure.

Use of Biogas

Biogas can be used for cooking, lighting, generation of power (electricity) and for running diesel engines / tubewells on dual fuel system i.e. mixing it with diesel @70-80%. The requirement of biogas for different purposes is as given below:

Biogas Plant Models

Different designs of biogas plants are used in various parts of the world depending upon the local climatic conditions and purpose of biogas utilization. Most common designs are constant pressure based floating gas holder plant and constant volume based dome type plants.

Floating Drum Type Biogas Plant Fixed Dome Type Biogas Plant

Mode of Implementation

The proposed project would be implemented by a Dedicated Project Management Unit (PMU) which shall be established. The Director General Agriculture (Field) will act as Project Director. The Punjab province would be divided into four zones indicating names of districts in each zone. The Directors of Agriculture Engineering at Multan, Faisalabad and Lahore, and Director Soil Conservation Rawalpindi would be designated as Deputy Project Directors incharge of concerned zones. The Field Engineers at districts and divisional level shall also monitor the construction and operation of biogas plants / tubewells. They will submit their reports to PMU / Director General Agriculture (Field) Punjab on fort-nightly basis.

Hiring of Consultant Firm

An international consultant firm, or its joint venture with national consultant, would be hired in accordance with PPRA (2014) rules. The Consultant shall finalize the tender documents and including specifications of the biogas plants for floating type and fixed dome type. It shall also evaluate the technical and financial proposals of contractor firms to install the plants on turnkey basis.

Pre-Qualification of Contractor Firms

The Pre-qualification Committee (PQC) shall be constituted with Additional Secretary (Planning) of Agriculture Department, to act as its convener. The PMU shall issue advertisement in the national press as well as at PPRA website inviting technical and financial proposals from the contractor firms for the construction of the proposed biogas plants on turnkey basis. Choice would be given to the contractors / firms to submit its proposals to operate in one zone, or in all areas of Punjab.

The consultant shall evaluate technical proposals of contracted firms in 1st stage and make recommendations for technical prequalification of potential eligible firms to the PQC. The eligible short listed firms shall be asked to submit financial proposals which shall also be evaluated by the consultant.

Distribution of Biogas Plants

The distribution of plants to 36 districts of Punjab has been made based upon the population of diesel tubewells in the concerned districts. However, South Punjab districts have been given 10% additional allocation of biogas plants compared with other districts. A total of 20,000 biogas plants shall be constructed and connected with diesel tube wells initially. With the success of these tube wells it shall be replicated to achieve the target of 100,000 biogas tube wells as desired by Chief Minister Punjab.

Allotment of Biogas Plants

Applications for allotment of biogas plants shall be invited through national press. Application forms shall be made available free of charge in the offices of Assistant Agricultural Engineers at District level, Deputy District Officer Agriculture (Extension) at Tehsil level and Agriculture Officers (Extension) at Sub Tehsil levels as well as at Agriculture Department website (www.agripunjab.gov.pk). Last date for submission of applications will be announced in the advertisement.
