TOR – DESIGN AND INSTALLATION SERVICES

TITLE 

Provision of services to design and install a 250 kW anaerobic digestion plant at Greenland Landfill or Newton Industrial Estate in Barbados.

INTRODUCTION

The Barbados Investment and Development Corporation (BIDC) is an agency of the Government of The Barbados Investment and Development Corporation (BIDC) is an agency of the Government of Barbados with specific responsibility for promoting and facilitating industrial and export development. The Corporation is currently undergoing a strategic pivot to restructure Barbados’ manufacturing industrial landscape, centered around three (3) key pillars. These pillars are the ocean economy, bio economy and design economy. The Corporation aims to contribute to the diversification and growth of the Barbados economy through new investment, increased exports and employment creation. This will be achieved by fostering the development of competitive manufacturing and related services companies under the three (3) pillars. To this end, we wish to engage the services of a firm to design, build and install a 250 kWh biogas plant at Greenland Landfill or Newton Industrial Estate in Barbados.

BACKGROUND

The Government of Barbados propositions development of a vibrant bioenergy sector with 100% renewable energy transformation by 2030, owing to rising population size, high transportation costs, and extreme vulnerability to exogenous shocks. Bioenergy can contribute to a more secure, sustainable, and economically-sound future by providing domestic clean energy sources, reducing Barbados’ dependence on foreign oil, create green jobs and revitalize key service sectors such as agriculture and manufacturing. Through deployment of bioenergy technologies, Barbados will emerge as a regional leader in the clean energy economy.

Anaerobic digestion is mature technology exploited globally for waste management and resource recovery. In this biological process, micro-organisms breakdown of organic matter in an oxygen-free environment into biogas and a bio-fertilizer. Biogas is composed of methane (50-70 %) and carbon dioxide (30-40 %) with trace amounts of water vapor, hydrogen sulfide and other gases. Raw biogas can be converted directly to electricity and heat in a generator or upgraded to biomethane through removal of carbon dioxide and other contaminants. Compressed biomethane is carbon neutral and interchangeable with conventional natural gas. Applications of biomethane include cooking, industry processes and vehicle transport. The residue from anaerobic digestion of organic material is a low odor, pathogen free and nutrient-rich slurry that can be stored and used as biofertiliser or other value-added materials.

PROJECT OVERVIEW 

The project seeks to design and install a 250 kWh anaerobic digestion plant at Greenland Landfill or Newton Industrial Park, requiring approximately 6000 tonnes of biomass input per year and generating approximately 2 MWh of electricity annually. Feedstock for anaerobic digestion will be various organic waste streams (food waste, roadside grasses, industrial wastewater, etc.) from BIDC’s industrial estates. The digester design should include the following components: feeding system, fermenter, gas treatment system, gasbag storage with analyser, gas flare, 250 kWh generator and digestate phase separator. The biogas generated will be injected into the national energy grid. The project objectives and deliverables are given below.

PROJECT OBJECTIVES 

The objectives of this project are to:

  1. Design 250 kWh anaerobic digestion plant in partnership with BIDC’s technical staff.
  2. Build and install a biogas system at Greenland Landfill or Newton Industrial Park with national grid connection for electrification and digestate storage.
  3. Perform preliminary testing of the biogas facility.
  4. Provide training on operation and maintenance of the plant.

SCOPE OF WORK

The scope of work will include, but is not limited to the following: 

  1. Site verification of project before plant construction. 
  2. Assessment of the proposed substrate input feed/blends.
  3. Plant construction drawings with a detailed feasibility study and recommendations for the size of the project based on proposed feedstock availability. 
  4. The civil works construction (construction of digester, inlet, outlet and feedstock pre-treatment facilities) should be done in line with the best engineering practices and quality assurance standards.
  5. Test run and commissioning of biogas system (e.g. digester structural test, leakage test in digester and pipelines, measuring instruments check test, etc.)
  6. In the case of electrification, the supply and installation of electrical and electronic equipment (e.g., generator, control panel, switch board, load controller, all earthing and lightning protection equipment) and other related accessories should be the responsibility of the firm.
  7. Provide appropriate training to BIDC’s technical staff on the operation and maintenance of the plant.
  8. Supply of standard operation and maintenance manuals.

COMPANY EXPERIENCE

Interested firms must demonstrate their level of experience in design and construction of large biogas plants systems. A summary of relevant projects undertaken to date should be provided. Additional information (e.g. project completion certificate) may be supplied to support the claims.
