class RUFAS.routines.manure.manure_treatments.composting.Composting(weather, time, manure_treatment_config: ManureTreatmentConfig)#

Bases: BaseManureTreatment

Class for managing and simulating the composting process of manure treatment.

This class simulates the composting process by considering various factors like weather, manure characteristics, and composting configurations. It provides methods for daily update of compost characteristics such as methane emissions, nitrogen content, and carbon decomposition. The calculations are based on standard composting models and environmental factors.
