Evaluating the economic feasibility of co-digesting manure and food waste in northern New York

Co-digestion is an option to explore given society’s desire to remove organics from landfills and the potential for higher volumes of renewable natural gas.

February 22, 2023

Lauren Ray and Peter Wright

The anaerobic co-digestion of dairy manure and food waste can provide significant methane emission reduction by avoiding emissions from both the long-term slurry storage of raw manure and the landfilling of organics, while additionally producing a renewable fuel that can replace fossil fuel sources.

Renewable energy options from biogas

December 22, 2021

Lauren Ray and Peter Wright

Anaerobic digestion of dairy manure and other organic material (e.g., food waste) produces biogas that can be used for renewable energy options.

RNG development opportunities: Considerations before a contract

December 22, 2021

Lauren Ray, Peter Wright, and Jennifer Bockhahn

Renewable natural gas (RNG) production from dairy manure is an opportunity for farms to obtain an additional income while also participating in the reduction of greenhouse gases (GHG), moving the dairy farm toward sustainability.

Food waste coming on the farm? Consider where the nutrients go and manure processing for nutrient export

March 8, 2021

Peter Wright, Karl Czymmek, and Tim Terry

Public policy is increasingly evolving to reduce or divert waste from limited landfill space. One way to accomplish this is by reducing the many tons of organic waste such as food processing waste, food scraps, and spoiled fruits and vegetables that are landfilled annually.

Food waste in digesters

December 2, 2020

Peter Wright and Curt A. Gooch

Forty percent of food in this country is wasted. At the same time, nearly 2.8 million New Yorkers struggle to have enough to eat. Food also makes up 18% of New York state’s solid waste stream and is filling up landfills.

Manure management to reduce greenhouse gases: What can dairy farms do?

December 2, 2020

Peter Wright and Curt A. Gooch

Concern is worldwide about how to control the anthropogenic emissions of greenhouse gas (GHG) emissions. GHGs include carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O), and are expressed as CO2 equivalents (CO2 eq.).

Facility planning

Peter Wright and Tim Terry

Dairy farming is a constantly changing business. Farming for the long-term requires a facility that changes as well. Expansion, new technology and new enterprises may all be in every sustainable farm’s future.

Siting manure storages revisited

December 9, 2019

Karl Czymmek and Peter Wright

To properly recycle nutrients, and to reduce the potential for nutrient and pathogen losses to the environment, dairy farmers will be planning, constructing, and using more manure storage systems.

Controlling compaction: Do’s and don’ts

March 13, 2019

Peter Wright and Joe Lawrence

Farming is ever-changing and improvements to perform timely field operations can impact soil health. Larger, road-ready trucks and equipment with higher tire pressures and larger axle loads made to spread manure, plant, spray and harvest quicker can cause severe soil compaction.

More manure storage? Consider your operation and your neighbor’s concerns

February 26, 2018

Peter Wright

Recycling dairy nutrients back to the land needs to be timely to preserve nitrogen and to avoid environmental losses. Manure storages are an integral part of the manure management system on the farm to make sure this is possible.
