Lamb Canyon is a Class III Sanitary Landfill covering 1189 acres, with 144.6 acres permitted for landfilling. Opened in 1970, its service area includes Beaumont, Banning, San Jacinto, Hemet, Coachella Valley, Pine Cove, Idyllwild, Cherry Valley, Cabazon, Homeland, Romoland, and Winchester. In 2022, it processed an impressive 606,481 tons of waste.
Waste Management and Sustainability
Our tour began at the scale house, where incoming vehicles are weighed to calculate the amount of waste delivered. With approximately 300 vehicles weighed daily, this step is essential for effective landfill management. Because of increasing customer traffic, the facility is currently upgrading its scales, roadways, and traffic signs.
Our next stop was the organics collection and composting area. Composting at this site is a 15-day process that turns green waste (excluding food waste) into compost used for erosion control within the landfill. There are plans to make compost available to the public at the Reuse Store.
Exploring Landfill Operations
Heavy machinery, including dozers and compactors, is used to break down and compress the waste. Pipes collect methane gas and carry it to a flare station where it is burned and safely released to the atmosphere as carbon dioxide and water vapor. A drainage system collects leachate, the liquid filtering through the landfill, to protect groundwater. Leachate is then stored in tanks and recycled for dust control within the landfill. Parts of the landfill also have a liner to contain leachate.
At night, waste in the active part of the landfill is covered with tarps to shed surface water, prevent fires, and reduce scavenging by animals which spread disease. Drones and falcons are used to keep birds at bay.
Surprisingly, the landfill also contains a 200-acre conservation area, providing habitat for a variety of sensitive plant and animal species including western sycamores, mountain lions, burrowing owls, and red-tailed hawks.
An Eye-Opening Experience Open to All
At the end of our tour, we received gift bags containing recycled and reusable goodies. More importantly, we left with a better understanding of where our trash goes and the engineering required to protect the environment. The volume of waste managed here emphasizes the importance of recycling, reusing, and reducing waste in our daily lives.
If you're interested in exploring Lamb Canyon Landfill, free guided tours are available from March through October, Monday through Thursday, for groups of 10 to 42 people. For more information, visit the Riverside County Department of Waste Resources website at https://rcwaste.org/education-center.

In my previous blog, I gave an overview of the first two days of COMPOST2023. The event, hosted by the The US Composting Council in January, was an outstanding learning and networking experience. In Part 2, I'm excited to discuss the rest of the event, including the conference sessions at the Ontario Convention Center and Demo Day at One Stop Landscape Supply.
After the keynote, I wandered over to the Exhibit Hall, eager to check out the vendors and information tables. Major equipment vendors such as Komptech and Ecoverse showcased their massive composting machines, while product manufacturers offered samples of compostable bags and utensils. One of the biggest trends was biochar—a carbon-rich, charcoal-like substance created by burning organic material without oxygen. It was interesting to see that even pistachio shells can be used to produce this substance! When blended with compost, biochar enriches the soil by increasing its moisture retention, nutrient content, and microbial activity.
The final presentation I attended on opening day was “Healthy Soils for Healthy Parks: Los Angeles Urban Carbon Farm at Griffith Park” by Lynn Fang, a well-known educator and researcher in composting systems and soil science. LA Compost recently established its first park-based compost site at Griffith Park, using food waste collected from local farmers market drop-offs. Lynn's presentation highlighted a demonstration project of the Healthy Soils for Healthy Communities Initiative, led by TreePeople in partnership with LA Parks and Recreation, Kiss the Ground, and LA Compost, to promote regenerative park management. The study site was a flat, grassy area south of Crystal Springs, where individual plots were treated with mulch from Griffith Park, compost from LA Compost, or no amendment as a control. After 9 months, the researchers found that mulch and compost increased the activity of soil organisms and the percentage of soil organic carbon.
Other panelists showed how technology can facilitate community composting. Tess Feigenbaum, the Cofounder and Operations Director at Epic Renewal in Rhode Island, announced plans to release a mobile application to help with compost site management, process tracking, data collection, and environmental impact reporting. Sashti Balasundaram, the Founder and CEO of WeRadiate, is leading the development of smart sensors for compost piles, which measure temperature and moisture with remote, real-time monitoring.
The final panelist to speak was Elinor Crescenzi, who shared data on the 31 Community Composting for Green Spaces (CCGS) sites in the Inland Empire. Despite a modest $224K budget for labor and infrastructure, these sites managed to divert about 510K lbs of food scraps and 3.7M lbs of organic material from landfills, resulting in emissions reductions equivalent to 908 metric tons of carbon dioxide. That's similar to taking 200 vehicles off the road for one year! In addition to the environmental impacts, the CCGS program also had significant community and social impacts, such as increasing healthy food access, community engagement and education, social support networks, and psychological well-being. Ninety percent of the sites are growing food in addition to making compost.
Another interesting session was “Compost Market Dynamics in California”. One of the speakers was Jeff Ziegenbein, the site manager of the largest indoor compost facility in North America, the Inland Empire Regional Composting Facility (IERCF). Located in Rancho Cucamonga, the facility produces over 200K cubic yards of compost annually from recycled wood and green waste, biosolids, and horse stable bedding using the Aerated Static Pile process. The composting area is completely enclosed to meet air quality regulations. The filtering system does such a good job at odor control I didn't even know this facility is literally in my backyard. The compost, marketed under the SoilPro brand, is used in a variety of applications, including landscaping, horticulture, turf management, agriculture, and roadways.
After attending the morning sessions, I returned to the Exhibit Hall for some Q&A with the finalists of the Emerging Composter Competition. The first place winner was Greg Mankowski of Evolve Pet Composting Services and Consultation in Michigan. His business is very timely, as more and more states, including California, are passing laws to allow human composting. Second place was Justin Brann of Crystal Coast Compost in North Carolina, who composts food waste from many sources, including residences, businesses, farmers markets, and events. Third place was Jameson Meyst of Juicycles, who collects unpicked fruit from San Diego orchards, juices it onsite, and distributes juice and fruit popsicles to the community while composting the remaining waste.
My favorite day of COMPOST2023 was Demo Day, which took place at One Stop Landscaping Supply in Redlands. The place is huge, making it the perfect setting for demonstrations of large-scale composting equipment. As a volunteer, my day started early to direct traffic to the parking area and hand out safety gear to the attendees.
Despite the loud noise of the equipment, the wild burros grazing around the parking lot seemed unfazed. Having only heard about herds of burros roaming San Timoteo Canyon, I was thrilled to see them up close. Although they were quite shy and wandered away when approached, many drivers stopped to snap some photos before heading out.
If this blog has piqued your interest in COMPOST2023, you can find the recordings at Compost University on the US Composting Council website. I'm already looking forward to next year's conference at the Ocean Center Convention Center in Dayton Beach, Florida from February 6th to 9th. The theme of COMPOST2024 is “Making Waves”, which is fitting given the impact composting is sure to have for years to come.

I couldn't believe it when I heard that COMPOST2023, billed as “the world's largest composting event”, was going to be held in Ontario, California in January. What were the odds that a composting enthusiast such as myself would be so close to the action? I'm so glad I was able to attend as a volunteer! This year's theme was “Capturing Carbon Renewing Soil”, emphasizing the importance of composting in reducing carbon emissions and enhancing soil health.
COMPOST2023 ran from Monday, January 23rd to Friday, January 27th, starting with two days of pre-conference activities. On the first day, I attended the Cultivating Community Composting Forum at the Ontario Convention Center. The second day was a Field Day with bus tours of local composting sites. I attended conference sessions at the Convention Center on Wednesday and Thursday and volunteered for Demo Day at One Stop Landscape Supply on Friday. It was a lot to absorb in such a short time.
The Institute for Local Self-Reliance (ILSR) coordinated the Cultivating Community Composting Forum and related Field Day activities. ISLR's Composting for Community Initiative works to advance “local composting to create jobs, enhance soils, protect the climate, and reduce waste through advocacy, training, research, demonstration sites, and coalition building”. The goals of the forum were to share best practices and build support for small-scale, community-based composting.
After a short break, the forum attendees reconvened for two peer-to-peer chat sessions on topics including scaling up, business and mission planning, funding and financing, and communications. I attended the sessions on community building and composting methods and best practices. These chats gave me the opportunity to share experiences with composters from across the country–from Peels & Wheels Composting in New Haven, Connecticut to ReMark Composting Solutions in Detroit to Hart's Worm Farm in Irvine.
The afternoon agenda consisted of two concurrent presentation sessions followed by two panels. One of the most memorable presentations was “Generating Excitement About Community Composting in an Urban, Chronically Marginalized Community” by Marvin Hayes and Kenny Moss of the Baltimore Compost Collective. Marvin is the Executive Director of the Collective which collects food scraps from residences and composts them at the Filbert Street Community Garden. Kenny, a student leader in the youth entrepreneurship program, helps manage the composting operations. In a catchy poem, Marvin described the role of composting this way: “Learn so we don't have to burn. Starve the incinerator. Feed the soil. Feed the Community! Clean air for Baltimore.” In 2022, the Baltimore Compost Collective served over 300 customers and increased its waste diversion by 40%.
Kourtnii Brown told the story of how the California Alliance for Community Composting (CACC) launched 120 community composting hubs with a $1.54M Community Composting for Green Spaces grant from CalRecycle. The network of composting sites spanned the state in 6 regions: the Bay Area, Fresno & Central California, the Inland Empire, Greater Los Angeles, Sacramento & Northern California, and Greater San Diego. CACC provided on-site support with skilled staff, infrastructure, community building, and program development. In the summer of 2021, CACC held a Soil Stewardship Training retreat (also called “Soil Summer Camp”) at Amy's Farm to train the trainers at the composting sites. Training recordings are available for public view on YouTube. Since 2020, the sites have diverted millions of organic waste from landfills and produced thousands of cubic yards of compost. The first round of CalRecycle funding just ended in January, and organizations have submitted applications for a second round.
Of the two afternoon composting site tours, I opted for the one that included Temple Beth Israel in Pomona, Claremont Friends Meeting, and the Buddhist Tzu Chi Foundation in San Dimas. Temple Beth Israel was the newest composting site we visited. There are an impressive number of raised beds on the property (around 20 from what I remember), where onions, herbs, greens, and other vegetables are grown in partnership with Uncommon Good. Ten small businesses provide food waste for composting next to the planting beds.

Does growing a vegetable garden sound like something you'd like to do, but you don't feel equipped? So, here's the deal. Find some dirt, and then plant. It's that simple. If you want to grow food, the first step is to find some dirt. Consider the usable ground you have. Take a look around. Maybe it's that patch of front lawn that you're tired of mowing, or haven't mowed at all. Could it be the bare spot in the back where the dog likes to poop? Step One is to find some dirt, and don't be judgy about the dirt you have. Your dirt is full of potential.
Your objective is to give your dirt some tender loving care, and your soil will return the favor by giving you healthier plants and better produce. Your soil's mineral composition is what it is, but one element we can be altered is organic material. No matter what kind of dirt you have, adding organic matter will make it better. Organic materials include grass clippings, fallen leaves, straw, wood chips and bark, hulls, plant clippings (chopped small) and everyone's favorite...manure. Now, here's an important point: it takes time for the organic materials to break down and start to enrich the soil, to become usable to plants. So, what's the best and quickest way to get those things into your soil? Compost. Compost is already mostly decomposed organic matter, so it mixes into the soil and continues to decompose slowly, releasing nutrients to plants and improving soil texture. Compost costs money, but you can also make your own in as little as 2 to 3 weeks at little or no cost. This article has a complete description of DIY compost: Compost in a Hurry (UC ANR Publication 8037).
Think of mulching as another method of composting that involves placing a thick layer of organic matter on top of the soil and letting it decompose very slowly. It's even better to put a layer of newspaper or cardboard on the ground first, wet it, and then spread out the organic material on top, about 4 inches thick. The organic matter and the paper or cardboard underneath will break down over the next 6 to 10 months. To add plants, push aside the mulch, expose the paper or cardboard, and cut an "X" large enough to accommodate your plant. Fold back the flaps, dig a hole, and add your plant. When done, lay the flaps back in place and re-cover with mulch. Remember that front lawn that you're thinking could be a vegetable garden? This method of sheet mulching is one way you get rid of the grass! Cover it, mulch it, forget about it. If you want to learn more about lawn removal, here's an article containing complete instructions: Lawn Removal: Do It Right.
