Just when you thought it was safe to enjoy this blog over your morning cup of coffee, here’s an article on… urine?Really?Let me explain.Urine is a largely sterile, nutrient-rich resource that can be used in fertilizing plants. In fact, according to the Rich Earth Institute, the urine from one adult in a year can produce over 300 pounds of wheat — enough for nearly a loaf of bread per day.The Rich Earth Institute is a Brattleboro-based organization that’s at the leading edge of this little-known practice of urine collection and use — something that’s emerging in Sweden and a few other places. This past Friday night roughly 200 people gathered at the Strolling of the Heifers’ River Garden in downtown Brattleboro to hear Abe Noe-Hays and Kim Nace from the Rich Earth Institute, along with a New York City comedian/activist, Shawn Shafner, discuss the idea.I thought I should weigh in and describe some of the benefits — both from an energy and nutrient-flow standpoint. Conventional practiceWith conventional practice, human waste (urine and fecal matter) is mixed with large quantities of potable water and flushed down toilets. From there, it typically flows to municipal wastewater treatment plants where energy- and chemical-intensive processes use bacteria to break down organic wastes, separate out biosolids, kill pathogens, and release that water into rivers or aquifers.

I like the idea of not mixing human waste with potable water, and I’ve always felt that flushing away the nutrients in human waste was a lost opportunity. But when I learned about urine separation and use (believe it or not in a luncheon presentation on the topic at a conference in Houston, Texas in 2009), I began to see the benefits of urine separation over standard composting toilets.With standard composting toilets, most of the nitrogen in the waste ends up being volatilized as either nitrogen gas or ammonia — and lost into the atmosphere. With urine collection and use, the nutrients aren’t lost; they are recycled in a sustainable nutrient cycle.This is something we’re considering for Leonard Farm, though we have not installed such a system yet. For more information or to participate in ongoing studies, contact the Rich Earth Institute. SterilizationAccording to most experts, simply storing urine for a while in a sealed container is enough to kill bacteria, due to the high alkalinity and ammonia from the urine. But the Rich Earth Institute is experimenting with faster pasteurization systems that heat the urine (including with solar systems that circulate solar-heated fluid through heat exchangers in the urine tanks).They are also testing various strategies for controlling odor — likely the biggest hurdle we face with urine collection and use. Utilizing human urineWhen most people think of creating fertilizer from animal waste, they think of manure. Composted cow manure, for example, is widely sold in garden centers. But there are actually far more nutrients in urine than in fecal matter.In human waste, 88% of the nitrogen is contained in the urine, along with 66% of the phosphorous, according to Swedish research (see table at end of blog), while nearly all of the hazards — including bacterial pathogens — are contained in the fecal matter.The idea that the Rich Earth Institute has been advancing for the past several years is to collect human urine, sanitize that urine to kill any bacteria that may be in it (from urinary tract infections, for example, or fecal contamination), and then apply it on fields as a fertilizer.Abe Noe-Hays, who used to work for our company, BuildingGreen, has been leading the charge with this idea in the U.S. The Rich Earth Institute secured funding from the U.S. Department of Agriculture, through the Sustainable Agriculture Research and Education (SARE) program to study urine collection and use as fertilizer, and the Institute is into its second year of this study. Land applicationIn Sweden urine is being applied on food crops, but to date, with USDA support and permits from the State of Vermont, the Rich Earth Institute has stuck with less controversial applications on non-food crops — specifically hay fields.Initial results last year with undiluted urine and dilution rates of 1:1 and 3:1, dramatic improvement in hay production was seen (see photo).Because urine may contain pharmaceuticals, there is an important question about whether that poses a problem. This year, the Institute will begin an EPA-funded study to test whether residual pharmaceuticals in urine are taken up by vegetables grown on experimental plots. Collecting urineSpecialized urine-separating flush toilets are available in Scandinavian countries with front chambers for capturing urine. Abe Noe-Hays manufacturers a urine-separating composting toilet, and the Institute provides special toilet insets for urine collection. On a larger scale, collection of urine from men’s rooms that have waterless urinals is very easy.With the help of Best Septic Service in Brattleboro, the Institute collected 3,000 gallons of urine from over 170 participants in 2013. Does a Composting Toilet Stink Up Your House?GBA Product Guide: Composting Toilet SystemsGBA Encyclopedia: Green Plumbing SystemsDo Low-Flow Toilets Really Work?Natural Building In NicaraguaQ&A: Experiences with grey-water and composting toilets?Or, if we live in rural areas not served by a municipal sewer system, that wastewater flows into septic tanks where solids settle out and the effluent then flows into the soil through leach fields — in most cases with most of the nutrients in that waste filtering down into the underground aquifers. I learned when researching on-site wastewater disposal years ago for an article in Environmental Building News that the aquifers under rural New England towns almost always have nitrate levels that significantly exceed federal drinking water standards.At the same time, in the chemical industry, tremendous quantities of natural gas are used in the Haber-Bosch process (invented in 1915) to extract nitrogen from the atmosphere, which is made up of roughly 78% nitrogen gas (N2), to produce ammonia fertilizer, the mainstay of commercial agriculture.
China’s Dong Dong won the gold in the men’s trampoline at the Olympics on Friday, beating Russia’s Dmitry Ushakov. In a reversal of the results from the 2008 Olympics in Beijing, China’s reigning champion Lu Chunlong took the bronze, while Dong upgraded to gold from the bronze he won four years ago.Dong set himself the most difficult programme and it paid off, giving him a score of 62.990, more than a point higher than Ushakov.
The officials have expressed their suspicion about Sunil Narine’s quicker deliveriesWest Indies mystery spinner Sunil Narine has Monday been reported for suspect bowling action during a Champions League T20 match between KKR and Dolphins, yesterday in what turned out to be another ICC crackdown on chucking.The CLT20 organizing committee issued a media advisory late Monday night, confirming the development, that on-field umpires Anil Chaudhary and Chettihody Shamshuddin along with third umpire Kumar Dharmasena have expressed their suspicion about the quicker delivery bowled by Narine.”Mr Narine was reported by on-field umpires Anil Chaudhary and Chettithody Shamshuddin, along with third umpire Kumar Dharamsena at the conclusion of the match. The report specifically relates to the quicker ball bowled by Mr. Narine,” the press release states.”Under the CLT20 Suspected Illegal Bowling Action policy, Mr. Narine may request an Official Assessment from the BCCI Suspect Bowling Action Committee. Mr. Narine has been placed on the warning list and may continue to be selected to play and bowl for his team in a match,” the release further stated.However if Narine is reported again for the same problem, he will be debarred from bowling further in the Champions League T20 although he can play as batsman.”Under the CLT20 Suspected Illegal Bowling Action policy, if a player receives a report while on the warning list, the player shall be suspended from bowling for the remainder of the tournament and from bowling in any matches organised by the BCCI until such date as he is cleared.advertisement”A player suspended from bowling may continue to be selected to play in matches, however he will not be entitled to bowl.”Narine has been KKR’s primary weapon over the past four seasons and has helped the franchise co-owned by Bollywood star Shah Rukh Khan to win two IPL titles in last three He is also on top of wicket-takers list with 11 scalps to his credit in the current edition of CLT20.The ICC has instructed the on-field umpires to be vigilant about suspected chuckers with Pakistan’s off-spinner Saeed Ajmal already suspended from bowling in competitive cricket. In this tournament, two Lahore Lions bowlers Adnan Rasool and Mohammed Hafeez have been reported for suspect actions.

DOI: 10.1016/j.sna.2018.01.028 Now, a team of researchers at UBC’s Okanagan campus have developed a practical way to monitor and interpret human motion, in what may be the missing piece of the puzzle when it comes to wearable technology.What started as research to create an ultra-stretchable sensor transformed into a sophisticated inter-disciplinary project resulting in a smart wearable device that is capable of sensing and understanding complex human motion, explains School of Engineering Professor Homayoun Najjaran.The sensor is made by infusing graphene nano-flakes (GNF) into a rubber-like adhesive pad. Najjaran says they then tested the durability of the tiny sensor by stretching it to see if it can maintain accuracy under strains of up to 350 per cent of its original state. The device went through more than 10,000 cycles of stretching and relaxing while maintaining its electrical stability.”We tested this sensor vigorously,” says Najjaran. “Not only did it maintain its form but more importantly it retained its sensory functionality. We have further demonstrated the efficacy of GNF-Pad as a haptic technology in real-time applications by precisely replicating the human finger gestures using a three-joint robotic finger.” Provided by University of British Columbia Tissue paper sensors show promise for health care, entertainment, robotics UBC engineers advance the capability of wearable tech. Credit: UBC Okanagan The goal was to make something that could stretch, be flexible and a reasonable size, and have the required sensitivity, performance, production cost, and robustness. Unlike an inertial measurement unit—an electronic unit that measures force and movement and is used in most step-based wearable technologies—Najjaran says the sensors need to be sensitive enough to respond to different and complex body motions. That includes infinitesimal movements like a heartbeat or a twitch of a finger, to large muscle movements from walking and running.School of Engineering Professor and study co-author Mina Hoorfar says their results may help manufacturers create the next level of health monitoring and biomedical devices.”We have introduced an easy and highly repeatable fabrication method to create a highly sensitive sensor with outstanding mechanical and electrical properties at a very low cost,” says Hoorfar.To demonstrate its practicality, researchers built three wearable devices including a knee band, a wristband and a glove. The wristband monitored heartbeats by sensing the pulse of the artery. In an entirely different range of motion, the finger and knee bands monitored finger gestures and larger scale muscle movements during walking, running, sitting down and standing up. The results, says Hoorfar, indicate an inexpensive device that has a high-level of sensitivity, selectivity and durability.The research, partially funded by the Natural Sciences and Engineering Research Council, was recently published in the Journal of Sensors and Actuators A: Physical. Explore further Creating the perfect wearable device to monitor muscle movement, heart rate and other tiny bio-signals without breaking the bank has inspired scientists to look for a simpler and more affordable tool.
