For the next few weeks we’re right in the thick of it when it comes to leaf collection. Each year from the beginning of April to the middle of December, Baltimore County provides a special yard materials recycling collection, once every two weeks, to 70 percent (165,000) of the County’s individual and townhomes. Materials such as grass, leaves, and small brush are collected and taken to the Eastern Sanitary Landfill Solid Waste Management Facility (ESL) in White Marsh for composting. The goal of this program is to reduce the amount of organic matter that is being landfilled. In 2013 approximately 11,000 tons of yard materials from the County’s Yard Materials Recycling Collection Program were processed into compost.
County residents may also take yard materials and brush and branches to two of the County’s drop-off facilities for recycling. More than 17,200 tons of these items were taken to ESL and approximately 4,100 tons were taken to the Central Acceptance Facility (CAF) in 2013.
What happens to the grass, leaves and brush?
The items dropped off at CAF are processed into compost and mulch by Hollins Organic Products, Inc. The yard materials from the County’s Yard Materials Recycling Collection Program and the yard materials and brush and branches taken to ESL by residents are processed into compost and mulch by the County at ESL.
Large tree branches and tree trunks are run through a large piece of equipment called a tub grinder to make mulch. The smaller material (grass, leaves, and small brush) is piled in long rows called windrows. Another large piece of equipment, appropriately named a windrow turner, moves over the rows using rotating blades to break down, mix and aerate the material. This process of “turning” helps to create the proper conditions for efficient composting (“nature’s recycling program”) of the material. Depending on the weather and other factors, the material will generally stay in these rows roughly 90 days. This material is then run through a trommel screen to remove large and unwanted debris. The compost is then piled up, where it continues to “cure” until it is ready for use.
Compost is decomposed organic material (humus) that helps to enrich and condition the soil. Mulch is “shredded” wood that is used around plants, bushes, and trees as ground cover, and helps to protect root systems from the cold.
Free compost and mulch for residents
Baltimore County residents may pick up compost and mulch, free of charge, from ESL (6259 Days Cove Road, White Marsh, MD 21162). Before going to ESL, call the Solid Waste Management customer service number (410-887-2000) to check on the availability of compost and mulch. Residents will need to bring and fill their own containers.
DIY is best bet
Collecting and processing yard materials is a big and expensive task, so residents are encouraged to “lend a hand” and handle their yard materials at home, through methods such as grasscycling, leafcycling and home composting.

Baltimore County Recycling Division
Baltimore County is celebrating America Recycles Day in a big way this year, with the opening of its new Materials Recovery Facility (MRF) and transfer station in Cockeysville that sorts the tons of materials collected each day through the County’s very successful Single Stream Recycling Program.
The new single stream facility will definitely impress visitors as tons of recyclables travel on numerous conveyor belts and are sorted multiple ways, including the use of optical sorters that shoot blasts of air to separate bottles and cans from paper. The highly automated equipment will allow the new MRF to process 35 tons of recyclables per hour, with the capacity to sort more than 70,000 tons of recyclables per year.
Our new MRF is not just impressive to look at, but it will also allow the County to hold on to the full economic benefits of high value recyclables collected from residents. Collectively, the new transfer station and single stream MRF are expected to generate approximately $750,000 to $2 million per year revenue after expenses, depending on market conditions.
The opening is just in time to celebrate America Recycles Day, a national campaign to educate and encourage individuals to recycle. What better way to participate and show that Baltimore County recycles, than to make sure that you are recycling all that you can!
