Local economic resilience and economic specialization in Greece during the crisis
Regional Science Policy &Practice, EarlyView., 2023 Abstract This paper scrutinizes the issue of economic resilience, aiming to detect the existence of a systematic link with economic specialization. To this end, the paper conducts an empirical analysis at the local (i.e., municipal) level of Greece during the economic crisis period (2009–2015), providing cartographic visualizations and spatial ...

Modified biochar derived from sewage sludge for purification of lead-contaminated water
Open EngineeringThe increase in wastewater collection and treatment systems has shown the need for adequate treatment and final disposal of the resulting sludge. Heat treatment through pyrolysis is an alternative, as it promotes the valorization of these wastes by ...

Jingshui jishu【目的】目前，我国已经形成了深度脱水-填埋、好氧发酵-土地利用、厌氧消化-土地利用、干化焚烧-建材利用这4条主流的市政污泥处理处置工艺路线，每种工艺路线都有各自的优缺点和适用条件，但每种路线的碳排放水平尚不明确，致使碳排放难以作为工艺比选测算指标落地应用。【方法】根据联合国政府间气候变化专门委员会指南，采用排放因子法，在确定核算边界后，全面核算了污泥从污水处理厂外运直至最终消纳的全流程碳排放量，包括处理处置过程中因甲烷(CH 4)和一氧化二氮(N 2O ...

Sludge Production and Disposal for Small Cold Climate Bio-Treatment Plants [PDF]
, 1972 Ultimate disposal of wastewater sludge has long been a problem which to a large degree has been ignored. Haney (1971) stated that: "Until process sludge can be handled with minimum environmental impact, we cannot claim to have a viable wastewater ...

Irrigation and Drainage, EarlyView.ABSTRACT Food security in Kerala depends on effective irrigation, but poor‐quality irrigation water poses threats such as salinity, sodicity and reduced soil productivity. Although past assessments have been localised, this study presents the first comprehensive, statewide evaluation of irrigation water suitability across 44 major rivers in Kerala.

Land Degradation &Development, EarlyView.ABSTRACT Soil degradation compromises ecosystem functioning. Biochar, a carbon‐rich amendment, has gained attention as a promising strategy to enhance soil structure and restore microbial balance. This study investigated the effects of two biochars, cashew bagasse biochar (CBB) and a co‐pyrolyzed biochar produced from sewage sludge and cashew pruning ...
