Assessment of co‐digestion of poultry litter and swine wastewater: the effect of enriched inoculum on biogas production

Journal of Chemical Technology &Biotechnology, EarlyView.
Abstract BACKGROUND Co‐digestion of substrates represents a viable strategy to enhance biogas production. This study evaluates biogas generation from the liquid fraction obtained through phase separation of co‐digested swine manure and poultry litter, to assess the influence of the inoculum‐to‐substrate ratio (ISR) and to analyze the effect of ...

Carbon footprint for farms in the Czech Republic: a benchmark‐based assessment

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Climate change is a pressing environmental and social challenge that demands effective monitoring of greenhouse gas (GHG) emissions. One widely adopted approach for this is quantifying the carbon footprint (CF). Given that agriculture is a major contributor to GHG emissions, we have developed a comprehensive framework for CF ...

The BIOGAS PRODUCTION IN INDIAN SCENARIO

Journal of Agriculture Biotechnology & Applied Sciences
  Cheap, clean, renewable, naturally occurring, and underutilized as an energy source is biogas. It ignites between 650°C and 750°C in temperature range and weights 20 per cent less than air. It burns as a colorless, odorless gas with a blue glow. It typically burns with 60 per cent efficiency in a regular biogas burner and has a caloric value of 20 MJ/

Biodegradable Polymers for Plant Nutrient Delivery and Recovery

Macromolecular Bioscience, EarlyView.
This review article discusses the use of biodegradable polymers to address several grand challenges in agriculture: to improve the delivery of nitrogen and phosphorous to crops, to optimize plant uptake, and to enhance the recovery of these nutrients from wastewater, to recycle them and reduce water pollution. Abstract The current use of fertilizers is

Practical Applications of Secondary/Extractive Electrospray Ionization (SESI): A Versatile Tool for Real‐Time Chemical Analysis

Mass Spectrometry Reviews, EarlyView.
ABSTRACT In the 1980s, researchers discovered the remarkable ability of electrospray plumes to effectively ionize gas‐phase molecules via secondary ionization. Around 20 years later—coinciding with the ambient mass spectrometry revolution—secondary electrospray ionization (SESI) and extractive electrospray ionization (EESI) coupled to mass spectrometry
