Terminology
A
Aerated Static Pile (ASP)
A controlled composting method used to efficiently decompose organic materials by providing controlled aeration (supply of oxygen) in a static or stationary pile. Parameters such as temperature, moisture levels, and aeration can be monitored and adjusted as needed to optimize decomposition.
B
C
Carbon Sequestration
Carbon sequestration is the process of capturing and storing carbon dioxide (CO2) from the atmosphere to mitigate climate change and reduce the concentration of greenhouse gases in the atmosphere. It is an essential component of strategies to combat global warming and its associated impacts.
The common abbreviation for "carbon sequestration" is "CCS," which stands for "Carbon Capture and Storage."
D
E
Environmental Impact
The United States Environmental Protection Agency (EPA) promotes composting as a sustainable waste management practice with several environmental benefits, particularly in the context of reducing carbon emissions.
By measuring waste diversion through Recipe weight and volume, composting programs and facilities can quantify their Environmental Impact and contributions. These key metrics support the sustainability of composting initiatives and promote environmentally responsible waste management initiatives.

I
Intake
The adding or introducing organic materials or feedstock into the composting system. It determines the composition of the compost mixture and influences the overall success of the composting operation. The intake phase involves gathering, preparing, and depositing organic materials into the composting system.
In-Vessel
A controlled composting method in which organic waste materials are processed within a closed, container-like system. Parameters such as temperature, moisture levels, and aeration can be monitored and adjusted as needed to optimize decomposition.
J
K
Key Performance Indicator (KPI)
A measurable value that demonstrates efficacy. KPIs are used to evaluate performance, track progress, and make informed decisions.
See KPIs: temperature, moisture, oxygen, turns.
L
M
Manual Log
A manual measurement and record of events, data, or information that is gathered by hand. The process of taking measurements or assessing quantities by human effort, typically using tools and instruments that require physical interaction.
Measurement
The process of assessing quantities typically using tools and instruments that require physical interaction. Measurements are made up of positions and key performance indicators (KPIs).
Microbial Activity
Beneficial microorganisms, including bacteria, fungi, and earthworms, play a crucial role in the decomposition process and are impacted by temperature, moisture and oxygen.
Moisture
Proper moisture levels (typically 40-60%) are necessary to support microbial activity. Inadequate moisture can slow down decomposition, while excess moisture can lead to anaerobic conditions.
N
Net Zero
Net zero, often referred to as "net-zero emissions" or "carbon neutrality," is a critical concept in the fight against climate change. It represents a state in which the balance between the amount of greenhouse gases emitted into the atmosphere and the amount removed from the atmosphere is essentially zero.
O
Other
A generalization of composting methods defined by days at PFRP temperatures and turns. Parameters such as temperature, moisture levels, and aeration can be monitored and adjusted as needed to optimize decomposition.
Oxygen
Adequate oxygen supply is essential for aerobic composting. Proper aeration helps prevent anaerobic conditions and ensures efficient decomposition.
P
Performance
A visualization of activity, or function measured against a processing method or set of criteria, standards, or expectations.
See KPIs: temperature, moisture, oxygen, turns.
See process: Aerated Static Pile (ASP), In-Vessel, Turned Windrow, Other
Process
The method defined by series of measurable events or actions required to produce a product.
See process: Aerated Static Pile (ASP), In-Vessel, Turned Windrow, Other
Position
The physical location of a measurement in relation to the total number of positions. Positions are assumed to be equally distributed across a physical space.
Process for Further Reducing Pathogens (PFRP)
A treatment process that consistently reduce pathogens (i.e., Escherichia coli (E. coli) bacteria, fecal coliforms, and Salmonella spp.) to below detectable levels based on temperature (at or above 131ºF or 55ºC) and turn (varying) controls.
Product
An item offered for sale after undergoing a controlled process to meet safety standards and become salable. See Product Type.
Product Type
The type of controlled processing materials undergo to become the product.
Q
R
Report
A PDF of performance.
S
T
Turn
Mixing of the windrows to introduce oxygen, control temperature, and evenly distribute microorganisms throughout a product. The frequency of turning can vary but is typically done on a schedule to establish proper composting conditions.
Turned Windrow
A composting method where compostable materials, are arranged into long, narrow piles or rows called windrows. These windrows are periodically turned or mixed to provide aeration. Parameters such as temperature, moisture levels, and aeration can be monitored and adjusted as needed to optimize decomposition.
U
V
W
Waste Diversion
Waste diversion refers to the process of diverting waste materials away from landfills, incineration, or other forms of disposal, and instead, redirecting them towards environmentally preferable alternatives. The primary goal of waste diversion is to reduce the amount of waste sent to landfills or incineration facilities, which can have negative environmental and economic impacts.
Windrow
Long rows organic materials which help with aeration and heat retention, promoting the breakdown of organic matter into nutrient-rich compost.
