a b s t r a c tHigh-solids anaerobic digestion (HSAD) processes, when applied to different types of organic fractions of municipal solid waste (OFMSW), may easily be subjected to inhibition due to organic overloading. In this study, a new approach for predicting these phenomena was proposed based on the estimation of the putrescibility (oxygen consumption in 20 h biodegradation, OD 20 ) of the organic mixtures undergoing the HSAD process. Different wastes exhibiting different putrescibility were subjected to lab-scale batch-HSAD. Measuring the organic loading (OL) as volatile solids (VS) was found unsuitable for predicting overload inhibition, because similar VS contents corresponded to both inhibited and successful trials. Instead, the OL calculated as OD 20 was a very good indicator of the inhibiting conditions (inhibition started for OD 20 > 17-18 g O 2 kg À1). This new method of predicting inhibition in the HSAD process of diverse OFMSW may be useful for developing a correct approach to the technology in very different contexts.

“…Finally, the cost of the third phase is lower than the other two phases, if the production location is not far from the distribution grid [32]. The treatment of ofmsw as a substrate determines from one side the income because the process of urban waste is a paid service and from the other side also the The costs of biomethane production can be subdivided into three main phases: (i) biogas production; (ii) upgrading; and (iii) compression and distribution.…”

Biomethane: A Renewable Resource as Vehicle Fuel

2017

Abstract:The European Union (EU) has set a mandatory target for renewable fuels of 10% for each member state by 2020. Biomethane is a renewable energy representing an alternative to the use of fossil fuels in the transport sector. This resource is a solution to reach this target. Furthermore, it contributes to reducing carbon dioxide emissions, gives social benefits and increases the security supply. Sustainability is reached also when the economic opportunities are verified. This work studies the profitability of small plants of biomethane, which is sold as vehicle fuel using the Net Present Value (NPV) and Discounted Payback Time (DPBT). The paper shows in detail the method used for the economic assessment of two typologies of feedstock recovered: (i) municipal solid waste and (ii) agricultural waste. Detailed information about the various parameters that affect the profitability of biomethane is given, and several case studies are analyzed as a function of two variables: subsidies and selling price. The results support the commercialization of small-scale plants, reducing also several environmental issues. The role of subsidies is strategic, and the profitability is verified only in some case studies.

“…The assay is regarded as the same as the BMP test (Schievano et al, 2008). It is also criticised for being time-consuming as it requires up to 60 d (Schievano et al, 2009). In the case of ABP assay, the batch tests are conducted in sealed serum bottles containing an inoculum, sample, and de-ionised water.…”
