The article focuses on a study by researchers at the U.S. Department of Energy's National Renewable Energy Laboratory (NREL) highlighting the significant amount of paper and cardboard waste that ends up in landfills across the U.S. Topics include the economic and environmental implications of this waste disposal method, the geographical distribution of landfilled paper and cardboard waste.

A peer-reviewed paper published in Nature Cities claims that urban agriculture has six times the carbon intensity of conventional agriculture. The paper is based on survey results from gardens in France, Germany, Poland, the United Kingdom, and the U.S. The authors used a model called Ecoinvent to calculate emissions, but the assumptions in the model were not shared. The study found that urban farms had lower emissions than traditional agriculture within three years of establishment, while individual and collective urban gardens had higher emissions. The paper acknowledges the benefits of urban agriculture, such as better eating habits and a connection to nature and neighbors, but suggests that current practices may need improvement.

A paper published in November 2023 in Environmental Health Perspectives discusses the potential presence of contaminants in compost produced from urban food and yard waste, such as pesticides, lead dust, and PFAS. The research team conducted case studies in Boston, Seattle, San Francisco, and New York City, examining waste-to-compost activities and legislation. The authors argue that inequities in composting practices are partially due to historical marginalization and loss of land, leading to food inequality among communities of color. They recommend that cities address these inequities by providing multilingual and multimedia communication and education about composting, and by engaging with volunteer garden coordinators and community organizers to advocate for the needs of community farmers and growers.

The article focuses on the initiation of a pilot residential food scraps collection program by the Division of Waste Services in Nashville, Tennessee, involving 750 single-family homes since October 2023. Topics include the program's weekly collection by Compost Nashville, the inclusion of soiled paper and BPI-certified compostable products, and the motivations behind the pilot as part of Nashville's Zero Waste Master Plan to increase waste diversion and address limited landfill capacity.
