Environmental Interests and Mathematical Model of Self-Heating in Large Scale Compost Piles

Within a matter of weeks or even days (after the accumulation of materials) compost piles see an increase in internal temperature (50 to 70 °C) due to biological self-heating. In some cases biological self-heating has initiated spontaneous combustion, but there is very little information that describes the relationship between these two phenomena. It is important to investigate this relationship, because biological-heating has also been observed during the storage of municipal solid waste, industrial fuel waste, and landfills in addition to large-scale composting operations. Using the single first-order ODE (ordinary differential equation) with few fit parameters describing the generic steady-state behavior of the system (compost pile) determined by Nelson et al. (2003) researchers considered a two-dimensional, spatially-dependent model containing biological and chemical activity, which ignored the depletion of cellulosic materials, biomass, and oxygen, reducing the model to an energy equation.

This is super interesting and I might be able to use it to develop my project!
