A Howard County study showed that organic waste makes up 30% of the local municipal solid waste stream. Organic waste in landfills is a significant source of methane (CH4) generation and subsequent emissions. Methane has more than 25 times the global warming potential of carbon dioxide. Therefore, it is critical to reduce methane emissions wherever possible.
Diversion techniques such as composting organic waste can reduce methane generation. Ensuring that methane generated in landfills is captures and managed using best practices is also very important.

Howard County currently has a yard trim collection composting program that serves half of the homes in the County and focuses on food and yard waste. The “Feed the Green Bin” program expands on the yard trim collection by providing optional bins to add food waste collection. Feed the Green Bin is available to 35,653 homes—53% of the County’s households with County service for yard trim collections.
In addition, the Alpha Ridge Landfill has a very high-tech and effective composting operation that produces high-quality products and has received certification of the U.S. Composting Council’s “Seal of Testing Assurance.”

Individuals should also make a conscious effort to eat more plants as part of a well-rounded diet, as raising livestock accounts for nearly 15% of direct global emissions each year. This high number is due to the clearing of land to house and feed livestock and the direct emissions livestock like beef produces. Eating a plant-rich diet can also provide an added benefit of improving your health.
Project Drawdown, a comprehensive ranking of climate solutions based on their potential to reduce greenhouse gas emissions, rated this action as fourth out of the top 100 actions to reduce emissions worldwide.

Call to Action: Reduce food waste at home and in the grocery store and switch to a more plant-based diet.
Participate in Howard County’s curbside composting program. Drop off wood waste and yard trim and purchase HoCoGro compost, mulch, and blended topsoil. Support local farms to reduce the food waste produced during the shipping process.Share to Social Media
Although difficult to quantify in a local GHG inventory, national and global GHG accounting shows that the amount of waste created per capita in the US contributes significantly to overall GHG emissions. Reducing waste at the source is the most cost efficient and impactful step we can take to reduce emissions from non-organic waste.
Howard County is focused on reducing consumption of waste-heavy products like single-use plastics that generate GHG emissions in their production, transportation, and disposal. Adopting sustainable procurement practices throughout municipal operations can help the County's government lead the way for the community to similarly identify opportunities to reduce waste.

Events provide an especially good opportunity to implement waste reduction practices. While events are fun, they produce large amounts of waste that often go towards the landfills – including food scraps, food ware, paper, cardboard, and other materials that could otherwise be recycled. Promoting zero waste practices at events can help promote a culture of sustainability that can help reduce the amount of waste that we produce, and therefore the amount of pollution and greenhouse gases that we emit.
Let’s Go Zero Waste, A Guidebook for Organizations on Zero Waste Events, was created by Chesapeake Conservation & Climate Corps member Vanessa Holloway during her tenure with the Howard County Office of Community Sustainability. The step-by-step guide offers tips on conducting a waste audit, practical ways to reduce waste at events, community resources for waste reduction, and case studies of Howard County nonprofits that have had successful waste reduction efforts. View an accessible, text-only version of the guide.
