3i’s Clean Energy Systems can use any number of materials as a fuel source.  A single material can be used as a primary fuel source or a combination of materials can be formulated into a custom matrix briquetted feedstock. Use of non-fossil fuel waste materials as a biofuel precursor repurposes waste streams as a fuel source for electrical and thermal energy production thus alleviating waste disposal and landfill capacity pressures.

Our systems can be configured to produce the following outputs:

Co-generation              – Electricity + Heat

Tri-generation              – Electricity + Heat + CO2

Quad-generation         – Electricity + Heat + CO2 + Chilled Water/Air

Below is a listing 3i Clean Energy System input materials that can be used as fuel and also system energy and gas compound outputs:

3i Clean Energy System - Inputs

Farms and agricultural operations including greenhouses produce waste materials as a by-product of cultivation activities.  These by-products are organic matter and qualify as a biomass material in that they are living or recently living organisms.  By serving as a biofuel source, these waste materials are diverted from waste and landfill disposal thus providing a sustainable and renewable form of fuel for energy generations.

Agricultural wastes can be recovered and processed into fuel briquettes and utilized as a fuel source input for 3i’s Clean Energy System.  Agricultural waste materials can include

  • Plant vines from greenhouses
  • Field crop reside
  • Culls from crops or processing operations
  • Waste Fruit, Vegetables & Organic Matter
  • Manure

Biomass is organic matter derived from living, or recently living organisms. Biomass can be used as a source of energy and it most often refers to plants or plant-based materials which are not used for food or feed.  Biomass materials can be recovered from waste, repurposed from waste streams or can be produced to serve as a feedstock for biofuel production.

Biomass Materials can include:

  • Algae
  • Wood
  • Plants
  • Grain Husks/Hulls

Recovered materials comprised of polymers such as polyethylene films and post-consumer items can also be briquetted and used as gasification feedstock to produce syngas for the co-generation system.  Polymer-based materials have a high calorific energy content thus containing increased energy per unit volume of material over that of other feedstock types.

Other forms of waste materials can be processed into feedstock briquettes suitable for the gasification process and include solid waste, biosolids, filtrate materials and many others.  The matter should be similar in type and quality to ensure that the gasification process is supplied with a consistent energy content material.

3i offers a national waste recovery and sorting program for materials generated by quick service restaurant chains.  The recovered and sorted materials serve as feedstock for gasification and CHP energy generation.  The materials include, waxed cardboard, food wastes and plastics.

Tires are high in BTU content and can be briquetted into a suitable feedstock for the gasification process.  There is an abundance of this material in most regions thus ensuring a consistent fuel supply.

Natural gas can also be used as a fuel source input for a 3i Clean Energy System.  The gasification process can be bypassed or eliminated if Natural Gas only is used.  Natural Gas can also be used in combination with other fuel material types.  Syngas derived from gasification of other feedstock materials can be blended with natural gas to be used by the co-generation engine.
