“…Biowastes, biomass and industrial wastewater have been used for the biological production of hydrogen (Mizuno et al, 2000;Noike et al, 2002;Kádár et al, 2003Kádár et al, , 2004Valdez-Vazquez et al, 2005;Kothari et al, 2012;Rama Mohan, 2015;Sharma and Ghoshal, 2015). Hydrogen is an energy carrier (not a fuel) and is one of the potential options to replace fossil fuel, as it is a renewable source with a moderate footprint on GHG emissions following combustion (Kothari et al, 2012;Amoo and Fagbenle, 2014).…”

Pulp and paper mill sludge (PPMS) is an organic residual generated from the wastewater treatments. PPMS management involves economic, environmental and social costs that will likely increase in the future as landfilling tends to be reduced or banned in certain jurisdictions. The reduction or the banning of landfilling may be considered as a climate change mitigation measure since organic waste disposal is normally associated with greenhouse gas (GHG) emissions. This critical review aims to (1) describe the variety of the current and emerging PPMS management practices that are alternatives to landfilling and (2) underline the crucial need for GHG emission assessments. The management practices of the three main PPMS types (primary, secondary and de-inking) comprised in this review are land application (agriculture, silviculture, land reclamation and composting), energy recovery (combustion, anaerobic digestion, pyrolysis, bioethanol, hydrogen production and direct liquefaction) and integration in materials (biocomposite, cement, asphalt and adsorbent-absorbent). Future research should focus to increase the comprehension of known GHG determinants from the PPMS management practices and reveal unknown factors. Life cycle analyses, based on direct GHG emission measurements, are needed to determine GHG emissions from current and emerging practices and plan a responsible future reduction or banning of landfilling. Such analyses will contribute to assist decision makers in implementing the best PPMS management practices with the least impact on climate change.
