TL;DR: There was a positive correlation between antibiotics and ARGs commonly detected in WWTPs, except for β-lactam antibiotics and bla genes, and most of antibiotics had lower levels in the period 2010-2019 in Asian countries than that in period 1999-2009 in North American and European countries.

TL;DR: In this paper, an updated review on fast pyrolysis of biomass for production of a liquid usually referred to as bio-oil is provided, including the major reaction systems.
Abstract: This paper provides an updated review on fast pyrolysis of biomass for production of a liquid usually referred to as bio-oil. The technology of fast pyrolysis is described including the major reaction systems. The primary liquid product is characterised by reference to the many properties that impact on its use. These properties have caused increasingly extensive research to be undertaken to address properties that need modification and this area is reviewed in terms of physical, catalytic and chemical upgrading. Of particular note is the increasing diversity of methods and catalysts and particularly the complexity and sophistication of multi-functional catalyst systems. It is also important to see more companies involved in this technology area and increased take-up of evolving upgrading processes. © 2011 Elsevier Ltd.

TL;DR: In this paper, the authors estimate that the amount of municipal solid waste (MSW) generated by urban populations is growing even faster than the rate of urbanization and that by 2025 this will likely increase to 4.3 billion urban residents.
Abstract: Solid waste management is the one thing just about every city government provides for its residents. While service levels, environmental impacts and costs vary dramatically, solid waste management is arguably the most important municipal service and serves as a prerequisite for other municipal action. As the world hurtles toward its urban future, the amount of municipal solid waste (MSW), one of the most important by-products of an urban lifestyle, is growing even faster than the rate of urbanization. Ten years ago there were 2.9 billion urban residents who generated about 0.64 kg of MSW per person per day (0.68 billion tonnes per year). This report estimates that today these amounts have increased to about 3 billion residents generating 1.2 kg per person per day (1.3 billion tonnes per year). By 2025 this will likely increase to 4.3 billion urban residents generating about 1.42 kg/capita/day of municipal solid waste (2.2 billion tonnes per year).

TL;DR: In this paper, a statistical meta-analysis was performed with the aim of evaluating the relationship between biochar and crop productivity (either yield or above-ground biomass) with an overall small, but statistically significant, benefit of biochar application to soils on crop productivity, with a grand mean increase of 10%.
