Abstract

Dog feces are a known source of nutrient, pathogen, and plastic pollution that can harm human and ecosystem health. Home composting may be a more environmentally sustainable method of managing dog feces and reducing this pollution. While composting is an established method for recycling animal manures into low-risk soil conditioners for food production, few studies have investigated whether household-scale compost methods can safely and effectively process dog feces for use in backyard edible gardens. A broad range of literature on in situ composting of dog feces is evaluated and compared according to scale, parameters tested, and compost methods used. Studies are analyzed based on key identified knowledge gaps: appropriate compost technologies to produce quality soil conditioner on small scales, potential for fecal pathogen disinfection in mesophilic compost conditions, and biodegradation of compostable plastic dog waste bags in home compost systems. This review also discusses how existing methods and quality standards for commercial compost can be adapted to dog fecal home composting. Priorities for future research are investigation of household-scale aerobic compost methods and potential compost amendments needed to effectively decompose dog feces and compostable plastic dog waste bags to produce a good-quality, sanitized, beneficial soil conditioner for use in home gardens.

家用狗粪堆肥：当前问题和未来方向。

众所周知，狗的粪便是养分、病原体和塑料污染的来源，会损害人类和生态系统的健康。家庭堆肥可能是一种更具环境可持续性的管理狗粪便和减少污染的方法。虽然堆肥是一种成熟的方法，可将动物粪便回收利用，制成低风险的土壤改良剂用于食品生产，但很少有研究调查家庭规模的堆肥方法是否能安全有效地处理狗粪便，并将其用于后院的食用花园。根据规模、测试参数和使用的堆肥方法，对有关狗粪便就地堆肥的大量文献进行了评估和比较。研究分析的依据是已确定的主要知识空白：小规模生产优质土壤改良剂的适当堆肥技术、中亲环境堆肥条件下粪便病原体消毒的潜力以及家庭堆肥系统中可堆肥塑料狗粪袋的生物降解。本综述还讨论了现有的商业堆肥方法和质量标准如何适用于狗粪便家庭堆肥。未来研究的重点是调查家庭规模的好氧堆肥方法以及有效分解狗粪和可堆肥塑料狗粪袋所需的潜在堆肥添加剂，以生产出优质、消毒、有益的土壤改良剂，供家庭菜园使用。Integr Environ Assess Manag 2024;00:1-16。© 2024 The Author(s).综合环境评估与管理》由 Wiley Periodicals LLC 代表环境毒理学与化学学会 (SETAC) 出版。

期刊介绍： Integrated Environmental Assessment and Management (IEAM) publishes the science underpinning environmental decision making and problem solving. Papers submitted to IEAM must link science and technical innovations to vexing regional or global environmental issues in one or more of the following core areas: Science-informed regulation, policy, and decision making Health and ecological risk and impact assessment Restoration and management of damaged ecosystems Sustaining ecosystems Managing large-scale environmental change Papers published in these broad fields of study are connected by an array of interdisciplinary engineering, management, and scientific themes, which collectively reflect the interconnectedness of the scientific, social, and environmental challenges facing our modern global society: Methods for environmental quality assessment; forecasting across a number of ecosystem uses and challenges (systems-based, cost-benefit, ecosystem services, etc.); measuring or predicting ecosystem change and adaptation Approaches that connect policy and management tools; harmonize national and international environmental regulation; merge human well-being with ecological management; develop and sustain the function of ecosystems; conceptualize, model and apply concepts of spatial and regional sustainability Assessment and management frameworks that incorporate conservation, life cycle, restoration, and sustainability; considerations for climate-induced adaptation, change and consequences, and vulnerability Environmental management applications using risk-based approaches; considerations for protecting and fostering biodiversity, as well as enhancement or protection of ecosystem services and resiliency.
