TG-FTIR and Py-GC/MS analyses of pyrolysis behaviors and products of cattle manure in CO2 and N2 atmospheres: Kinetic, thermodynamic, and machine-learning models

Energy Conversion and Management, 2019
The increased amounts of manure have become an issue of environmental management due to the rapid growth of livestock industry. This study quantified the pyrolytic performance and gaseous products of cattle manure using (derivative) thermogravimetric ((D)

DDT degradation potential of cattle manure compost

Chemosphere, 2010
The purpose of this study was to investigate the ability of cattle manure compost (CMC) to degrade 1,1,1-trichloro-2,2-bis (4-chlorophenyl) ethane (DDT). DDT was degraded during composting and 1,1-dichloro-2,2-bis (4-chlorophenyl) ethane (DDD) was detected as a metabolic product.

The anaerobic co-digestion of food waste and cattle manure

Bioresource Technology, 2013
This study assessed the anaerobic co-digestion of food waste and cattle manure, in order to identify the key parameters that determine the biogas and methane yield. Results of both batch and semi-continuous tests indicated that the total methane production is enhanced in co-digestion, with an optimum food waste (FM) to cattle manure (CM) ratio of 2. At

Methane emission factors from cattle manure in Mexico

Bioresource Technology, 2001
Factors responsible for methane emission from cattle manure representing diverse climates, systems and functions of cattle production are presented. These factors were obtained by means of an experimental methodology developed for this project. It was considered that the temperature, moisture, handling of manure and the animals' feed ration affect ...

Biochar improves compost humification, maturity and mitigates nitrogen loss during the vermicomposting of cattle manure-maize straw.

Journal of Environmental Management, 2022
Maintaining humidification and inhibiting nitrogen losses during vermicomposting process have emerged to be key factors for high-quality productions. Previous data have showed outstanding functions of biochar addition in improving vermicomposting quality.

Cattle manure compost humification process by inoculation ammonia-oxidizing bacteria.

Bioresource Technology, 2021
The effectiveness of newly isolated ammonia-oxidizing bacteria (AOBs; T-AOB-2, M-AOB-4 and MT-AOB-2-4) in promoting organic matter degradation and humification of cattle manure compost was explored.

Microbial community composition, co-occurrence network pattern and nitrogen transformation genera response to biochar addition in cattle manure-maize straw composting.

Science of the Total Environment, 2020
A better understanding of the microbial group influencing nitrogen (N) dynamics and cycling in composting matrix is critical in achieving good management to alleviate N loss and improve final compost quality.

Rheological properties of dairy cattle manure

Bioresource Technology, 2005
Rheological properties are important for the design and modelling of handling and treating fluids. In the present study, the viscosity of liquid manure (about 10% total solids) was measured at different shear rates (2.38-238 s(-1)). The effect of temperature on the viscosity at different shear rates was also studied.
