Bioenergy, produced through the anaerobic digestion (AD) of renewable organic feedstocks, is considered to be one of the highly promising alternatives to fossil-derived energy. The anaerobic digestion residues have recently begun to be recognized as underutilized natural resources that have unrecognized value. This work is focused on the new added valorization of digestates obtained from the AD of organic substrates. Effect of digestates treatments and concentration on the properties of composites were investigated. The results showed an increase of mechanical and chemical resistance of the composites as a result of the heat treatment of digestates. Composite having 30% unsilanized calcined-digestate fillers was found to have the highest chemical and mechanical properties.

In an urban or suburban area, the sustainability of a waste management process is expected to be closely related to the territorial context and the local citizens’ behaviour. From this perspective, the implementation of the peculiar proximity waste collection system in a small town in Central Italy (San Costanzo) was considered. As compared to the previous road collection system in the same municipality, its environmental performance in terms of Source Separation Level (SSL), Waste Generation or Collection Rate (WGR or WCR) and Interception Rate (IR) was evaluated. An original analysis of the citizens’ monthly frequency and of their participation rate both in relation to the setting out of the Unsorted Residual Waste (URW) was also carried out. Following the full implementation of the new waste collection scheme, the SSL achieved almost 79%, the WCR of the URW decreased by about 82% and the most IR values resulted above 83%. From a social point of view, the study further highlighted that, with the new waste collection scheme active, more than 50% of users were accustomed to set out the URW at most 5 times per month and the corresponding participation rate to set out the URW was around 62%.

Using the renowned leisure boat-building sector in the Marche Region (Italy) as a case-study, this paper addresses the characterization of (1) the industrial waste generation from the building of composite material-based boats and (2) some chemical-physical properties of representative types of boat-building residues (plastic foam, hardened resin, fibre-reinforced composite residues, and sanding dust). A parametric evaluation based on the number of employees gave a representative unit generation rate per employee (UGRpE) of 1.47 tonswaste employee−1 year−1 for the entire Marche regional boat-building district, whereas evaluations carried out separately for three case-study companies provided values of 1.56, 3.07, and 1.12 tonswaste employee−1 year−1 as representative for a mass-produced motor boat builder (case-study company ‘1’), a customized sailing boat builder (case-study company ‘2’), and a mould and structural component builder (case-study company ‘3’), respectively. The original proposal and evaluation of two additional generation rates based on physical characteristics intrinsic to the manufactured product, i.e. the unit generation rate per boat area (UGRpA) and per boat weight (UGRpW), confirmed the higher waste generation for the sailing boat builder (representative UGRpA and UGRpW values of 0.35 tonswaste year−1 and 2.71 tonswaste year−1, respectively) compared with the motor boat builder (representative UGRpA and UGRpW values of 0.06 tonswaste year−1 and 0.49 tonswaste year−1, respectively). The chemical-physical property characterization of the selected residues revealed the following aspects: a general condition of low moisture contents; significant ash contents in the glass- and carbon-fibre composite residues and the correlated sanding dust; and relatively high energy content values in the overall range 14,144–32,479 kJ kg−1, expressed as the lower heating value.
