Duties and Responsibilities

  1. Scope of work, responsibilities and description of the proposed analytical work

It is proposed to upgrade the composting facility and enhance the composting operation by providing the technical and operational support to the composting of the wheat as a means to dispose of the remains from the port of Beirut explosion in an environmentally sound manner. The project will consider any additional support for the composting facility such as leachate management (part of the composting process). This will include:

  • Rehabilitation and/or cleaning of the existing leachate channel.
  • Construction of a collection tank and pump, after a detailed technical analysis is conducted in terms of design, need, viability and cost. The leachate has a high value of humic acid and therefore will be re-circulated to moisture the compost and accelerate the composting process.
  • Procurement of a pelletizing machine and bagging machine that will help in packaging the good quality compost that will be sold to farmers at fair prices (the income generated from selling the compost will be re-invested to maintain the sustainability of the facility).
  • Training of the operation team on methods to improve the composting process and on the cleanliness and management of the composting site. The capacity building component for improved composting process will be implemented with the support of an international consultant and will also include the testing of the compost product to ensure it is up to standard and safe to use. UNDP will consult with the KfW expert in this field as well to ensure approaches are aligned.
  • A quick cost-benefit analysis including financial assessment will be conducted for the solid waste management facility of Zahle to identify means to improve financial sustainability.
  • An Environmental and Social Management Plan (ESMP) for the solid waste facility of Zahle will also be conducted, including the landfill and composting facility, and measures integrated during UNDP’s implementation of the project.

The Consultant is mainly responsible to implement activity c, d, and e above


  1. Tasks and Responsibilities

Under the overall guidance of the UNDP Project Manager, the Consultant will be responsible to prepare the outputs mentioned below.


  1. Assessment of Current Compost Practices and Environmental Impact Assessment
  • Assess the current compost production practices and uses currently being used by the private contractor affiliated with the Municipality of Zahle
  • Identify the available resources including, but not limited to manpower and equipment used in the composting process
  • Review the current practices and compare to international best practices and market quality of the compost, and the pre-requisite conditions and knowledge
  • Determine the compost production gap in terms of quality (if any) and potential to fill this gap and improve the quality by enhancing the methods of production
  • Analyse the possible adverse environmental impacts from the current composting practices especially on soils and crops


  1. Compost Improvement Plan

Prepare a detailed action plan for the improvement of the compost process, including needed equipment and resources, along with their respective detailed specifications and cost estimates. The Compost Improvement Plan should include but not be limited to the below components:


  1. Market potential: based on international best practice, consider the current use of the compost within the Zahle context and analyse ways to improve the utilization of the compost
  2. Expansion potential:
  • Explore the potential of expanding composting from agricultural material to include animal manure, crop residues and/or others
  • Determine the needed equipment and upgrades to improve the composting practices in the facility
  • Provide detailed specifications and designs, costs and procurement plan for the needed equipment including market analysis and availability.
  • Consider the various aspects of the compost storage and packaging and recommend changes/upgrades as needed
  • Provide detailed specifications/BoQ for a pelletizing machine and bagging machine that will help in packaging the good quality compost that will be sold to farmers at fair prices
  1. Quality and environmental improvements:
  • Design and develop the mix design of the compost to be produced based on the best marketable standards
  • Identify practices for mitigation measures to protect the environment
  • Ensuring standards of quality assurance in implementing the activities in accordance with the most appropriate international and professional relevant practices
  1. Mixing compost from the SWM facilities with sludge from the nearby wastewater treatment plant and other sources to assess if this will improve the quality of compost:
  • Study the different environmental and economic performances of sludge composting alternatives (feasibility and viability)
  • Study the utilization of the sludge essential nutrients taking into consideration the potential presence of pollutants
  • Undertake an analysis of risks and opportunities
  • Consider a cost-benefit analysis of sludge management options that would consider co-composting versus biogas production or other options.


  1. Cost-Benefit Analysis for Zahle Solid Waste Management Facility
