ADJOURNMENT

Composting 101

What is Composting?

“managed process of bio-oxidation of a solid heterogeneous organic substrate including a thermophilic phase.” (BNQ, 2004)

Compost Biology

• Composting process is carried out by microorganisms and higher level fauna (macroorganisms).

• During composting, there is a succession of microbial species; the environment created by, or the byproducts of, one species invites the activity of another species.

• As a result, no single species persists though the entire range of conditions encountered during the compost process.

Compost Biochemistry

• Composting is a controlled process. The goal is to maintain conditions that encourage a healthy community of microbes.

• This is done by monitoring and manipulating six main process parameters.

Composting Process Overview

USCC 1st Level Compost Process Model

Recovery

• Final Inspection of feedstock(s) at the composting facility, and separation/removal of contaminants and non-desirable materials.

Feedstock Preparation• Preparing the feedstocks in a

manner that establishes optimal conditions for composting to proceed. May includes grinding to set particle size, blending bulking agents to establish porosity, blending feedstocks to optimize C/N ratio or pH, adding water, or inoculating the feedstock with microbes by recycling compost.

High-Rate Composting

• High temperature stage of composting process involving pathogen treatment (PFRP), feedstock degradation and biological stabilization of the compost.

Curing (Maturation)

• Biological finishing step to stabilize and mature the compost materials.

Odour Treatment

• Collection or otherwise control and treat odourous off-gases from the composting process.

Screening and Refining

• Removal of oversized materials (stones, bulking agents) and physical contaminants (glass, metals, sharps) to create a product suitable for the selected end use.

Storage and Packaging

• Storage of the finished product inventory (in a manner that preserves its beneficial properties) to meet seasonal market demand.

• Mixing with other products to produce compost or soil blends. Bagging for the retail market.

Composting Technology Overview

General Types of Technologies

• Static Piles

• Windrows

• Aerated Static Piles

• In-vessel

Low Cost

High Cost

Static Pile Method

• piles in windrows or cones

• passive aeration –chimney effect

• characterized by long processing times

• pipes sometimes added to improve air flow

Windrow Method

• aeration achieved by mixing or “turning” with front end loader of specialized equipment

• monitoring done manually

Aerated Static Pile

• positively aerated

• negatively aerated

• bunkers

• covered systems

In-vessel Systems

• static containers

• agitated containers

• tunnels

• agitated bays

• drums

• channels

Static Containerized Systems

• modular

• positive aeration with recirculation

• temperature feedback process control

• floor grate

• end doors with seals

• common scrubber & biofilter for odour control

• PLC control with customized HMI

Agitated Container Systems

• mixed material loaded into one end

• moving floor, spinners or augers mover material through container

• positive aeration with exhaust

• 7-14 day thoughput

Agitated Bay Systems

• generally for large scale systems

• positive or negative aeration

• highly automated

older newer

Tunnel Systems

• positive aeration with recirculation

• temperature feedback process control

• in-floor channels• aluminum doors with seals

• scrubber/biofilter for odour control

• PLC control with customized HMI

Drum Systems

• technology borrowed from cement industry

• drums rotate up to 1 rpm• slight incline combined with rotation causes material to move from end to end

• air injected at discharge end

• typically 1-3 day retention.

• combined with other technology for secondary composting

Channel Systems

• similar to agitated bays

• typically positively aerated

• material moved down length of channel by turner
