The objective of this study was to develop a tool to predict the quantity of biogas produced by a municipal solid waste (MSW) landfill site to allow the energy it represents to be exploited. The model proposed is based on a first-order kinetic equation which describes the production of methane during in-situ decomposition of MSW. This equation was applied to a landfill site considering the MSW mass as a series of layers of waste of differing ages. The equation includes three parameters: MPo, the methane potential of fresh waste which is specific to MSW, d, the in-situ life duration of the waste which depends on the landfilling conditions and Ti, the filling rate, i.e. the rate at which waste is placed in the landfill site. This simple model, usable for all types of landfill and, by virtue of the parameters it uses, closely represents the site operating conditions. The approach was applied to the Villeparisis site and predicted a methane production rate of between 270 and 410 m3h−1, quite close to the measured value of 300 m3.h−1. In addition, the possibility of simulating variable landfill rates and waste life durations can be used to guide site management techniques to optimize the valorisation of the biogas and provide a global approach to the problem by incorporating leachate collection into the biogas exploitation calculations.

Anaerobic digestion (AD) is a suitable management option for the energy valorization of many wastes, including the organic fraction of municipal solid waste (OFMSW). However, in some cases, long storage after the separate collection of this waste is required for management reasons, especially when the amount of waste to be treated temporarily exceeds the capacity of available AD plants. This study evaluates the biochemical methane potential (BMP) of the OFMSW after preliminary storage of 2, 6, and 10 days, in order to assess whether they are still suitable for AD or not. Moreover, the accuracy of three kinetic models (first order, Gompertz, and logistic models) in estimating the methane yield of stored OFMSW is tested. The resulting methane yield was between about 500 and 650 NmL·gVS−1 and slightly increased with the increase of the storage time after collection. Overall, this study has demonstrated that storage of OFMSW, when the collected amount of solid waste exceeds the treatment capacity of AD plants, a storage time up to 10 days does not impact the methane yield of the process.

Packed microcosms, consisting of 0.6 L-flask filled with tire chips (TC, a non-cost-recyclable non-biodegradable material) or ceramic cubes, were employed in the wet batch mesophilic anaerobic codigestion of a mechanically sorted organic fraction of a municipal solid waste with cattle manure. Two different waste mixtures were digested within four successive batch experiments, performed by collecting the digested waste and by refilling each microcosm with the same experimental mixture. Methane production yields related to the first experiment were comparable to those of non-packed identically developed microcosms, while they significantly grew during all the following experiences. No CH4-production lag-phase was observed since the second batch experiment. Similar results were obtained for both packing materials: however, the highest methane yields were achieved within bioreactors packed with TC in the presence of a mixture in which the volatile suspended solids (VSS) provided by the municipal waste represented the 55% of the total ones. Under such condition, a methane yield corresponding to the biochemical methane potential (BMP) calculated through a 6-month experiment with non-packed microcosms (176 ml/gVS) was attained in about 1/4 of the time. Importantly, the BMP can significantly grow up as a consequence of the approach described in this study.
