Meet NASA's latest Mars Rover: Will Perseverance find life in 2021? Although total nitrogen levels are fairly high (up to 12%), the bioavailability of this nitrogen may be low. Use the link below to share a full-text version of this article with your friends and colleagues. The results showed that HTT with a reaction temperature of 180°C, a reaction time of 30 min, feather‐water ratio of 1:5, and lime addition is sufficient to solubilize as high as 83% of the chicken feather protein. , published 7 June 2014, Learn a second language to slow ageing brain's decline, American chestnut set for genetically modified revival, Google Earth reveals suspected nuclear weapons facility in Pakistan, Double climate disaster may have ended ancient Harappan civilisation, CRISPR gene editing of brain cells might prevent Alzheimer's disease, Huge reservoir of fresh water found beneath the sea off Hawaii, Meat-free diets linked with greater risk of breaking bones, Covid-19 news: UK R number below 1.0 for the first time since August, AI can turn spoken language into photorealistic sign language videos, We seem to find larger animals more charismatic than small ones.

Nitrogen mineralization dynamics of liquid feather hydrolysates obtained by hydrothermal treatment. Liquid feather protein hydrolysate as a potential fertilizer to increase growth and yield of patchouli (Pogostemon cablin Benth) and mung bean (Vigna radiata). Another group uses their complex structure to make composite materials like printed circuit boards and fashion materials. Put together chicken feathers and carbon dioxide and you can make an important fertiliser. The second product is carbon micro-spheres, which Chen found can make a water-resistant coating. But even better, warm this substance to 60 °C and it releases ammonia, an ingredient in urea, a superior fertiliser. International Journal of Recycling of Organic Waste in Agriculture. Box 70, Dushanbe, Glavpochtampt, 734000 Tajikistan. How do mRNA coronavirus vaccines work? Currently, 2 per cent of the world’s energy is consumed making ammonia, using the energy-intensive Haber process. IOP Conference Series: Earth and Environmental Science. In this study, chicken feathers were subjected to hydrothermal treatment (HTT) with lime addition in the temperature range of 140–200°C to obtain a high N containing liquid product that can be used as a liquid fertilizer. Learn more. Heat chicken feathers to 600 °C for 3 hours in CO 2 and two useful substances form (Environmental Science & Technology, doi.org/s2h). One is ammonium bicarbonate, a fertiliser and food additive. “Sequestering carbon as ammonium bicarbonate or as urea is quite a smart idea,” says Walter Schmidt of the US Department of Agriculture in Beltsville, Maryland. Insights into thermal hydrolyzed sludge liquor - identification of plant-growth-promoting compounds. of Experimental Ecology and Biomethod, Institute of Zoology and Parasitology, Academy of Sciences of the Republic of Tajikistan, P.O. Fertilizer potential of liquid product from hydrothermal treatment of swine manure. The immune system: can you improve your immune age? Comparison on solid biofuel production from wet and dry carbonization processes of food wastes. Feather meal is used in formulated animal feed and in organic fertilizer. More than 5 million tonnes of chicken feathers are produced globally every year. Working off-campus? Bio‐based fertilizers are currently gaining interest as a method for reducing the use of chemical fertilizers and as a means for safe disposal of biomass waste. Chen says that getting urea from chicken feathers instead could save some of this energy. Surreal Californian oilscape wins climate change photography award, The dazzling winners of the British Ecological Society’s photo awards, Climate change may make autumn leaves fall early and store less carbon. Beyond plucking: Feathers bioprocessing into valuable protein hydrolysates. But combine the two in the right way and you can make an otherwise-scarce fertiliser. Energy Sources, Part A: Recovery, Utilization, and Environmental Effects. The produced liquid contained nitrogen of up to 3.4% and total amino acid content of 13.6%. Feathers, which are an abundantly available biomass and have a high N content, are a potential source of fertilizer nutrients. Sign up to read our regular email newsletters. Hydrothermal Carbonization of Cattle Paunch Waste: Process Conditions and Product Characteristics. Poultry feathers are rich with keratin protein and therefore they could be a source for good nitrogen fertilizer. Gasification and Properties of Chars Derived Food Waste by Pyrolytic and Hydrothermal Carbonizations. 2972 Chen’s idea for chicken feathers has some competition.

The objective of this study was to examine the effect of HTT conditions on the feather solubilization rate and the properties of the liquid products.
