The Basics of Composting
Mastering the fundamentals of composting empowers residents of Tempe, AZ, to transform organic waste into valuable soil amendment. Here's how to get started.
What Is Composting?
Composting is a natural process whereby organic material such as leaves, vegetable scraps, and coffee grounds are broken down by microorganisms. The result is compost, a nutrient-rich, soil-like substance achieved through decomposition that promotes soil health and plant growth.
Benefits of Composting
Reduces landfill waste: By composting, individuals can significantly cut down the amount of waste sent to landfills.
Enhances soil quality: Compost improves soil structure, providing a habitat for beneficial organisms that support plant health.
Environmental conservation: It contributes to the environment by reducing greenhouse gas emissions from decomposing organic material in landfills.
Basic Composting Principles
Balance: A mix of green (nitrogen-rich) and brown (carbon-rich) materials is essential for effective composting.
Aeration: Regular turning of the compost pile ensures proper oxygen flow, necessary for decomposition.
Moisture: Compost should feel like a wrung-out sponge, maintaining moisture without being waterlogged.
Size: Smaller pieces of organic material decompose faster due to increased surface area.
Green Materials: Vegetable scraps, grass clippings, coffee grounds
Brown Materials: Dry leaves, branches, cardboard
Compost is ready to use once it's dark, crumbly, and has an earthy smell. It can then be mixed into soil to enrich it.
Setting Up Your Composting System
Implementing a composting system in Tempe, AZ, involves selecting a strategic location, choosing the appropriate bin, creating an ideal environment for decomposition, and balancing materials rich in carbon and nitrogen.
Choosing the Right Location
A designated area in one's yard should be selected for the composting system, ideally situated in shade, sheltered from strong winds, and with convenient access to water. This mitigates the impact of the dry Arizona climate on the composting process.
Types of Compost Bins
Various bin options are available, from a simple mesh wire circle to repurposed wooden pallets or concrete blocks. For those who prefer a ready-made solution, commercial bins designed for efficient air circulation and ease of use can be purchased.
Creating the Ideal Environment
Water, air, and a balance between green and brown materials are essential to foster a thriving composting system. The bin must ensure adequate air flow and moisture levels, as too much water can lead to anaerobic conditions, while too little hinders decomposition.
Understanding Greens and Browns
A successful compost requires a balance between nitrogen-rich material ("greens" such as kitchen scraps and yard clippings) and carbon-rich material ("browns" such as dried leaves and branches). Typically, the composting process thrives with a ratio of 3 parts browns to 1 part greens by volume.
Key Components for Successful Composting
Successful composting in Tempe, AZ, hinges on managing four essential factors: the balance of carbon and nitrogen, proper moisture levels, adequate aeration, and the surface area of the compost materials. Understanding and controlling these aspects can transform organic waste into nutritious compost efficiently.
Balancing Nitrogen and Carbon
The carbon-to-nitrogen ratio (C ratio) is critical for compost success. An ideal balance is about 30 parts carbon to 1 part nitrogen. Carbon materials, often brown and dry, include shredded paper and shredded cardboard, providing energy for microorganisms. Nitrogen materials, typically green and moist, like fruit and vegetable scraps, supply the proteins needed for microbe growth.
Carbon-rich materials:
Shredded paper
Shredded cardboard
Dry leaves
Nitrogen-rich materials:
Grass clippings
Vegetable peels
Coffee grounds
Moisture and Aeration
Water and air are indispensable for composting as they support the organisms responsible for decomposition. The compost pile should be moist, like a wrung-out sponge, but not waterlogged, which can lead to anaerobic conditions and odor. Regular turning adds oxygen, which is as crucial as moisture for breaking down materials.
Ideal moisture level: ~50-60%
Aeration strategy:
Use a compost aerator tool
Size and Surface Area
The size of composting materials affects their decomposition rate. Smaller pieces expose more surface area to microbes and heat, accelerating the process. It's advantageous to shred or chop garden waste and kitchen scraps before adding them to the pile.
Recommended practices:
Chop large materials
Mix small with large pieces to prevent clumping
What to Compost
In Tempe, Arizona, the practice of composting is an effective way to repurpose organic waste into nutrient-rich soil. The following categories delineate the types of organic matter suitable for the composting process and address common fallacies regarding compost materials.
Acceptable Organic Matter
Food Waste: Fruits and vegetable scraps are excellent for compost. This includes items such as apple cores and carrot peelings. Food waste is a composting staple and should be free of oils or dressings.
Leaves: Dry leaves provide the necessary carbon balance to the compost and break down well.
Coffee Grounds: A rich source of nitrogen, coffee grounds are beneficial to a compost pile. They can be added directly without the need for compostable filters although these too can be included.
Tea Bags: Used tea bags are also compostable but should be free of staples.
Yard Waste: Includes grass clippings and plant trimmings, which should be pesticide-free to avoid harming the compost's microbial life.
Paper and Cardboard: Non-glossy cardboard and paper can be shredded and added to the mix, as they are carbon-rich materials.
Common Misconceptions
Meat and Dairy Products: These are often incorrectly believed to be compostable. They should be avoided as they can attract pests and cause odor issues.
Compostable Plastics: Not all 'compostable' plastics break down in a home composting system. These typically require industrial facilities to properly decompose.
Glossy or Coated Paper: Though paper is generally a good addition to compost, glossy or plastic-coated paper should not be added as they do not break down easily and can contain harmful chemicals.
Compost Maintenance and Troubleshooting
Maintaining an active compost bin and addressing common issues ensures a successful composting process. Proper compost maintenance encourages faster decomposition and produces high-quality compost, while troubleshooting helps in averting potential problems.
Turning and Aeration
Regular turning of the compost pile is critical for aeration, which accelerates the decomposition process. Aeration prevents the pile from becoming compacted, which can lead to anaerobic conditions and foul odors. Ideally, one should turn the compost every couple of weeks using a pitchfork or a compost aerator tool.
Temperature Control
The temperature inside a compost bin is an indicator of microbial activity. A healthy compost pile will generate heat, with internal temperatures often ranging between 130-160°F. To maintain optimal temperatures, check the pile’s warmth periodically and turn it to distribute heat evenly.
Dealing With Odors and Pests
Odors can arise from an imbalance in the composting materials or insufficient aeration. To combat odors, adjust the ratio of green to brown materials and increase the frequency of turning. Securely cover the compost to deter rodents, and consider a bin with tight-fitting lids or hardware cloth to prevent insects and other pests from invading.
Recognizing Finished Compost
Finished compost is characterized by a dark color, crumbly texture, and an earthy smell. It should no longer heat up after turning and should resemble rich soil. Once the compost reaches this stage, it can be removed from the pile and used for gardening and landscaping purposes.
Using Your Compost
After creating a nutrient-rich amendment from your kitchen and yard waste, it's time to enhance your environment. The compost you've produced from methods shared by the City of Tempe is a versatile resource that can invigorate a variety of settings.
In Gardens and Landscapes
Incorporating compost into garden beds and landscapes adds essential nutrients to the soil. It modifies soil structure, enabling better root growth and water retention. For vegetable gardens, blend compost into the top few inches of soil before planting. When applied around trees and shrubs, it acts as a natural slow-release fertilizer, providing plants with consistent nutrition.
As Mulch
Using compost as mulch helps maintain soil moisture, suppresses weeds, and prevents soil erosion. Spread a 2-3 inch layer of compost around your plants, taking care to avoid direct contact with the stems. This practice not only recycles organic material but also contributes to a healthier and more sustainable garden ecosystem.
For Houseplants
Houseplants benefit from a topping of compost, which can replenish depleted nutrients in the potting soil. Lightly sprinkle a 1/2 inch layer of compost on the surface, or mix it into the top inch of existing soil, ensuring that drainage is not impeded. This enriches the soil and promotes more vigorous houseplant growth.

In Tempe, Arizona, residents can elevate their composting efforts using advanced techniques like vermicomposting and hot composting. Each method accelerates the decomposition process through different means, providing effective ways to repurpose organic waste.
Vermicomposting
Vermicomposting employs the natural digestion abilities of worms to break down organic matter. In this process, specific species of earthworms, such as Eisenia fetida or Eisenia andrei, also known as red wigglers, are introduced to a mixture of organic waste and bedding material. These worms efficiently consume and process the waste, leaving behind nutrient-rich castings. As emphasized by the EPA, vermicomposting not only helps reduce landfill contribution but also produces a superior product for gardens.
Materials: Red wiggler worms, organic waste (fruits, vegetables), bedding (shredded newspaper, cardboard).
Conditions: Moist environment, 55-77°F (ideal temperature range).
Benefits: High-quality compost, can be done indoors, suitable for small-scale applications.
Hot Composting
Hot composting is an accelerated method that involves managing the pile to achieve higher temperatures, typically between 130-160°F. These conditions are created through a careful balance of 'green' and 'brown' materials, which include nitrogen-rich greens like kitchen scraps and carbon-rich browns such as leaves. Turning the pile regularly introduces oxygen, which, combined with the correct moisture level, catalyzes microbial activity. As the name suggests, hot composting generates heat, which helps to kill weed seeds and pathogens, resulting in a faster decomposition process.
Materials: Equal parts green (nitrogen) and brown (carbon) materials, water, composting thermometer.
Conditions: Frequent turning, moisture control, temperature monitoring.
Benefits: Faster decomposition, pathogen and weed seed reduction, suitable for large volumes of organic waste.
Environmental Impact and Waste Reduction
Initiatives for environmental sustainability in Tempe, AZ, include a focus on composting practices that help mitigate waste-related consequences on the ecosystem.
