“…Firstly, in the last years, researches are mainly focused on the development of technologies/management strategies aimed at preventing the biological SS production. For instance, Collivignarelli et al (2015bCollivignarelli et al ( , 2017aCollivignarelli et al ( , 2018 studied the minimization of municipal biological SS by means of a thermophilic membrane bioreactor (TMBR), focusing the attention also on factors affecting foam formation (Collivignarelli et al, 2017b). Details on other sludge minimization techniques can be found for instance in Collivignarelli et al (2019c) and Paul and Liu (2012).…”

“…As concerns the membrane processes, an innovative solution based on a thermophilic aerobic membrane reactor for the treatment of sewage sludge and high strength aqueous waste [22] is able to increase the ammonia content in permeate and the precipitation of nutrients (nitrogen and phosphorus) in the form of salts. Moreover, the proposed solution can be conveniently integrated in traditional wastewater treatment plants (based on a conventional activated sludge process) with the aim to reduce the content of nutrients in the discharged effluent and to recover the heat from the thermophilic aerobic reactor [23].…”

The proper recovery of resources such as nitrogen and phosphorus present in the manure from intensive livestock farming is essential in order to allow environmental sustainable zootechny especially in densely populated areas where these activities are historically prevalent. The experiences at full-scale established that the ammonia stripping allows recovery from 35% to 50% of nitrogen depending on the type of substrate treated with anaerobic digestion and on the nitrogen content/form in the digestate. This study focuses on the ammonia stripping on digestate derived from anaerobic digestion of livestock manure and corn silage. Two different full-scale plants are studied including a packed column and an air bubble reactor without filling material with the aim to reduce fouling issues due to the content of suspended solids in digestate. The main results suggest that the use of an air bubble reactor could treat digestate with high concentration of suspended solids. A deeper study based on a two-level factorial experiment highlights that the temperature is an important parameter that influences the ammonia removal yields. Thus, a proper management of available thermal energy is very important.

“…Agro-industry residues can also be applied in environmental engineering, including WW treatment. Currently WW can contain a huge number of pathogens (Collivignarelli et al, 2017b) and pollutants such as dyes (Suryawan et al, 2018), heavy metals (Burakov et al, 2018), surfactants (Collivignarelli et al, 2018(Collivignarelli et al, , 2019a, personal care products (Wang and Chu, 2016), pharmaceutical products and solvents (Collivignarelli et al, 2017c). Recently, research has focused on the application of agro-industry residues as alternative adsorbent materials due to (i) the low cost, (ii) the high availability of residues and (iii) their significant effectiveness on adsorption of pollutants (Collivignarelli et al, 2019d).…”

Valorization of agro-industry residues in the building and environmental sector: A review

Environmental pollution has become a relevant issue as the population rises and resources decrease. Reuse and recycling still have the greatest potential as they turn the waste into a new resource, representing the ‘closed-loop’ step of a circular economy (CE). Looking for new applications for agro-industry waste represents both an environmental issue, as its incorrect disposal is a cause of pollution, and a chance to exploit zero-cost natural wastes. The present review, with around 200 articles examined, focuses on possible reuses of these residues in (a) building construction, as additives to produce thermal and acoustic insulation panels, and (b) in water treatments, exploited for removal of pollutants. The selected materials (coconut, coffee, corn, cotton and rice) have industry production wastes with suitable applications in both sectors and huge worldwide availability; their reuse may thus represent a new resource, with an impact based on the production rate and the possible replacement of current inorganic materials. Along with possible implementation of the selected materials in the building industry and environmental engineering, a brief description of the production and supply chain are provided.
