Community-Scale Composting Systems : A Comprehensive Practical Guide for Closing the Food System Loop and Solving Our Waste Crisis

Whether you’re an engineer, community organizer, permaculturalist, public sector waste manager, farmer, or just a dirt lover, Community-Scale Composting Systems is the definitive manual on composting.


Composting at scales large enough to capture and recycle the organic wastes of a given community, whether a school, neighborhood, or even a small city, is coming of age, propelled by a growing awareness not only of our food waste crisis, but also the need to restore natural fertility in our soils. In-depth yet accessible, Community-Scale Composting Systems is a technical resource for farmers, designers, service providers, organics recycling entrepreneurs, and advocates of all types, with a focus on developing the next generation of organics recycling infrastructure that can enable communities to close the food-soil loop in their local food systems.

The main scope of the book is dedicated to compost system options and design, from basic sizing and layout to advanced techniques such as aerated static pile composting. Management techniques and operational considerations are also covered, including testing, feedstock characteristics, compost recipe development, and system-specific best management practices.

Though focused on recycling systems that include food scraps—the fastest growing sector of community-scale composting—the book is informed by and relevant to other composting sectors and will be a vital resource for anyone invested in diverting organic materials away from landfilling and incineration.

Topics covered include:

• Community-scale models
• Estimating organics from individual generators and whole communities
• Food scrap collection
• Compost system sizing
• Aerated static pile (ASP) systems design
• In-vessel systems selection
• Integrating animals with composting
• Compatibility with compost heat recovery, vermicomposting, and other specialized methodologies
• Composting best management practices
• Nuisance management
• Mitigating persistent herbicides
• End uses, marketing, and sales
  
  “This book provides a good and detailed consideration of the broad range of possible approaches and challenges to community aspirations to feed the soil while mitigating wastefulness. If you are thinking of rescuing wasted food in your community, you would be well advised to start by reading this book.”—Karl Hammer, founder and president, Vermont Compost Company
