Additional info
This study compares the environmental impacts of present PM and FW management strategies with an alternative co-digestion scenario. The co-digestion scenario performs better in most environmental impacts, and the N availability of the digestate is superior as well. Hotspots greatly influencing the environmental impacts are identified and mitigation methods are proposed. A low FW proportion in the co-digestion scenario cannot offset the negative impacts caused by the introduction of FW. For a farm with a PM production of 16,000 t/yr, at least 2000 t/yr FW is needed to ensure a negative GWP. These results can provide practical references to pig farmers, the gas industry and policy makers.

Assessment
This section contains a brief assessment of the FEFTS described.
There are 3 basic categories: General, Environmental and Socioeconomic assessment.
The purpose of this assessment is to give a quick overview to the potential FEFTS user of its application benefits.
For each question, the Likert scale is used with the following possible answers:
Strongly disagree, Disagree, Neither agree nor disagree (Neutral)/non applicable, Agree, Strongly agree
General
This FEFTS contributes to improve the energy profiles of farming systems:Environmental
The application of this FEFTS directly reduces fossil energy use, in terms of:- Tractors and vehicles fuel consumption
- Tools and equipment fuel consumption
- Manure reduction
Socioeconomic
The application of this FEFTS contributes to cost reductions of farming systems:Keep in mind that this assessment is subjective, based on publicly available information.
All registered users are asked to evaluate each FEFTS and when an adequate number of reviews is gathered the results depicted here are updated. Each review is screened in order to avoid malicious practices.
FEFTS providers who do not agree with the assessment results, can send their inquiry to info@agrofossilfree.eu and a direct action based on their petition will be taken.
