Tackling the Fastest Growing Domestic Waste Stream Takes Circular Thinking

first_imgWith the summer time in full swing, most of us are thinking about vacation, beaches, and finding ways to escape on our next adventure. My idea of an adventure is embedding myself in nature by going on a nice long bike ride.It’s important to spend time with nature to remind us of its beauty, fragility and our responsibility to protect it. Advancing sustainability is a key focus for our 2030 vision. We have a responsibility to protect and enrich our planet together with our customers, suppliers and communities, and to embed sustainability and ethical practices into all that we do.Addressing the fastest growing domestic waste streamFor our part, we are focused on addressing the growing challenge of electronic waste. For those not familiar, e-waste is one of the fastest growing waste streams on the planet. Estimates show approximately 50 million tons of e-waste is generated worldwide, but only 29% of it is recycled properly. Unfortunately, the other 71% is typically stockpiled in household garages, handled informally, or thrown into the landfill.We do our part to enable our customers to recycle responsibly, and this time last year, we shared news about a new partnership with the Basel Action Network (BAN) introducing an asset tracking pilot program to use technology utilized by BAN to provide greater transparency into our own US electronics recycling programs.1 year later: What have we learned? Well, for starters, we learned GPS-based asset tracking works, and we learned that the majority of our downstream recycling processes are operating as we expect. But the pilot program did expose some early vulnerabilities which helped us quickly take corrective action and addresses the operational gap.Additionally, the pilot has led to us making global tracking technologies part of Dell’s existing electronics disposition partner audit program. As I just shared, e-waste is a significant issue. The numbers above justify how we need more innovative solutions to meet the increasing challenge of recycling electronics. BANS’s e-waste tracking service is one way we are tackling the problem.Ensuring responsible recycling is only one piece of solving this problem.The bigger opportunity is to think circular from the very beginning and remove waste from the entire process. When waste becomes a design principle and an input into our manufacturing process, e-waste goes away. The most recent example of this is a collaboration with suppliers Seagate and Teleplan (a storage device recycling/recovery specialist). Together we’ve created a new closed-loop process to recover the rare earth magnets from recovered enterprise equipment. The magnets are then reformed for reuse in new hard-disk drives – most notably the Dell Latitude 500 series laptop. Not only is this a winning example of circular economy, but it’s finding ways to reuse rare earth metals, which have serious environmental and health consequences if not properly managed.As we embrace a new 2030 vision: Progress Made Real, our success will be dependent on new business models and new ways of partnering with customers, suppliers, manufacturers, or NGOs.  This is where the innovation happens and how we will get the scale to make progress real.last_img read more

Jamaica murder rate passes 900 in 2017

first_imgJamaica’s murder rate continues to climb unabated.Police blotters indicate that more than 900 murders have been committed on the island with some 285 days (seven months and 16 days) gone in 2017.PandemoniumOn the night of Tuesday August 15, pandemonium broke out at Chancery Lane in Kingston, close to the middle class community of Meadowbrook.A man was murdered in full view of people at a bus stop, route taxi operators and other members of the public at the busy intersection.The victim has been identified as 29-year-old Damain Forrester, of a Greater Portmore address in St CatherineForrester had left work and was standing by a section of the bus hub on Chancery Lane in Meadowbrook.  The morning of that fateful day he had received a call that caused him to worry. “He was just not himself,” said a co-worker. “His wife just had a baby about one or two weeks ago. I don’t know but that call bothered him.”Killer dressed in blackAbout 9:47 PM a white car drove up near to where he was and as it stopped a man dressed in black from head to toe exited the vehicle. Then the car drove off. Damian was at the bus stop with co-workers. The man who had stepped out of the car was a killer.The killer calmly walked up to Forrester and shot him once in the head before walking off for a moment, turning back to his victim and pumping at least six more shots in his head as he lay on the ground. The shooting caused a mini stampede as bystanders scampered for cover.The gunman then rushed to the white car parked on another section of the roadway, for an easy escape.Damain had been working at a nearby supermarket for less than a month. Gang related, reprisals, domestic disputesThe troubling murder rate has the Jamaican authorities and law enforcement scratching their heads as lawless marauders run amok. Police in the island claim the majority of murders are gang-related, or reprisal killings. The police also claim a number of murders are the result of domestic disputes.Visitors to the island are rarely killed and make up about two percent of all homicides committed in the last decade.last_img read more

Man Utd hit new low in dismal Burnley loss

first_imgHe hasn’t been helped by an injury to United’s top scorer Marcus Rashford, who has been ruled out for up to three months with a stress fracture in his back.With Rashford sidelined, the sight of France forward Anthony Martial in pain on the turf after an early aerial challenge would have been a huge concern for Solskjaer.Martial was eventually able to gingerly rejoin the fray, but sliced horribly wide with the goal at his mercy when he was picked out by Aaron Wan-Bissaka.Juan Mata fared no better with an embarrassing miscue when he tried to meet Wan-Bissaka’s cross with a close-range volley that ended up hitting his own leg.Daniel James went closer with a towering header that belied his diminutive size and forced Nick Pope to tip over.United were made to pay for their profligacy as Burnley snatched the lead in the 39th minute.Exposing United’s weakness at set-pieces, Ben Mee rose above Nemanja Matic and nodded down to New Zealand striker Wood, who got in front of the ponderous Harry Maguire to fire home from close-range.Wood’s 10th goal of the season was the first time Burnley had scored in the first half of a Premier League game in their last 12 games.United had now kept just four league clean-sheets all season and Solskjaer responded by introducing teenage forward Mason Greenwood at the interval.They still looked nervous and Fred was fortunate not to concede a comical penalty after handling when he tripped in his own area.Just when Solskjaer thought it couldn’t get any worse, United hit rock bottom in the 56th minute.A quick exchange of passes carved open United’s defence and found Rodriguez, who ignored the tight angle to unload a blistering strike that cannoned down off the bar and over the line to clinch Burnley’s first win at Old Trafford since 1962. Share on: WhatsApp Manchester, United Kingdom | AFP | Troubled Manchester United crashed to a third defeat in their last four Premier League games as Burnley powered to a surprise 2-0 win at Old Trafford on Wednesday.Ole Gunnar Solskjaer’s side were rocked by Chris Wood’s first half opener before Jay Rodriguez scored with a superb strike after the break.It was a dismal display from fifth placed United, who are in such poor form that there will be fresh questions about Solskjaer’s job security in the coming days.Solskjaer could have no complaints about a result that laid bare everything wrong with a rudderless team lacking steel in defence, creativity in midfield and a cutting edge up front.United trail six points behind fourth placed Chelsea but, given how they have struggled so often this season, the only surprise is that the gap isn’t bigger.Stunned by their second home league defeat this season, United’s tally of 34 points is their lowest after 24 matches of a top-flight season since 1989-90.United must regroup to avoid more misery in the FA Cup fourth round against Watford or Tranmere on Sunday before they head to Manchester City looking to overturn a 3-1 first leg deficit in the League Cup semi-finals next Wednesday.If United are knocked out of both cup competitions, Solskjaer is likely to find the patience of supporters who idolised him during his playing days will dwindle even further.Those that hadn’t already fled before full-time made their feelings known as they booed United off at full-time.Losing to a Burnley side who had won one of their last 30 Premier League matches against established top-six opposition was another blow for United fans already depressed by the prospect of bitter rivals Liverpool winning the title for the first time since 1990.The gap between United and runaway leaders Liverpool stood at 30 points after Sunday’s defeat at Anfield and there is no sign of Solskjaer bridging the divide any time soon.– United made to pay –last_img read more

Minisplit Heat Pumps and Zero-Net-Energy Homes

first_imgWhat do you want to know more about?Do you have any questions related to designing a net-zero-energy building? Now’s your opportunity to get some of your questions answered by someone who has done it for himself and others. As they say, good judgment comes from experience, and experience comes from bad judgment! Perhaps my experience can help you along with one of your challenges.Here’s how this “mini-consultation” will work:Step 1. In the comment section below, write a specific problem that you’re facing or question that you have about zero-net-energy home design. Feel free to ask multiple questions if you’d like. Please, be as specific as possible.Step 2. You must submit these questions by Friday January 10 at 9:00 p.m.Step 3. I will select five of the best questions and write in-depth responses to those questions on Thursday January 16th.The goal is that these responses will have tangible impact on your work, and that it can then help others that are facing similar issues. Think of this like a mini-consultation with me. I’d like to go into more detail that I can in the comment section of an article in a forum. Wish list1 – An efficient, affordable air-source heat pump that provides space heating, space cooling, and domestic hot water.2 – An air-to-water unit that makes 160°F water at outdoor temperatures of 0°F, to serve as a drop-in replacement for existing fossil-fuel boilers. For the last several years, just about every project I’ve worked on other than large university buildings has used minisplit heat pumps for heating and cooling. Why?1 – There is no combustion and no need for a chimney or vent.2 – In space conditioning applications, heat pumps can provide heating and cooling.3 – The equipment installation costs and the operating costs compare favorably with other options.4 – Heat pumps are a natural partner to solar electric systems to achieve zero-net-energy buildings.In addition, we’re using heat pumps to make domestic hot water (DHW) and even to heat swimming pools. All of these products are air-source heat pumps (ASHP) which extract heat from the air to supply heat to the load.We’ve been metering the energy consumption at a number of buildings using heat pumps. We’ve seen through our own experience, and through more precise lab-based measurement efforts such as those performed by NREL and others, that the Japanese minisplit heat pumps live up to their performance claims in terms of both output and efficiency. What I know (or I think I know…)(Caution: unfunded research follows.)1 – Compact superinsulated homes in climates with design temperatures of 0°F or more can often be heated with a single zone unit with the wall cassette located in the main space. As long as the doors to other rooms remain open, the temperatures in those rooms will usually be within 2°F of the space where the cassette is located. We’ve put electric radiant panels in bedrooms in these homes, and there’s a large variation in how much people use them; the variation seems to be driven mostly by whether the door is open.2 – Without specific detailed measurement of in situ Coefficient of Performance of the units (COP), the amount of energy used by these units, metered separately, agrees well with the usage predicted by simple energy models.3 – In temperatures below design temperatures, the units have enough capacity to heat the houses even though we don’t size them with an intentional safety factor. Recently it dropped to -5°F here on Martha’s Vineyard, and my Fujitsu ¾-ton ducted unit was heating my basement (because the air handler is in the basement, and I haven’t got the ducts installed yet) and one-story house, a total of over 2,400 gross square feet, to 70°F. The load had to have been more than the published output of the unit at that temperature (14,000 BTU/hour). I was impressed. The best single zone systems have little drop-off in capacity down to 5°F.4 – The cold climate Mitsubishi Hyperheats are rated down to -13°F and we’ve seen them running at temperatures below -20°F. Colleagues are reporting minisplits not specifically rated at these temperatures running happily at them nonetheless.5 – Treating these units like furnaces and implementing significant temperature setbacks doesn’t appear to save a lot of energy because they will run at full speed when the temperature is set back up, which is a less efficient operating point. And because they aren’t usually oversized for the house load, it can take a long time to get the house back up to temperature. At my house we regularly set down to 66°F overnight, or when we are both going to be gone all day at work, and set back up to 70°F when we’re there – unless the outdoor temperature is going to be in the teens or below, in which case we don’t set it back.6 – Properly designed and installed ducted systems are usually really quiet. However, I made the mistake on my new system of installing the air handler with a very short return – about three feet and one elbow to the return grille – and I’m going to have to do some sound absorption. The supply side is really quiet. Most of our ducted systems are hard to hear, most of the time.7 – The systems with high outputs at low temperatures are also delivering air at higher temperatures than traditional heat pumps, which is more comfortable. I’ve measured supply air at 120°F from my air handler this past month.8 – If the homeowners let the filters get dirty, output can drop dramatically! These aren’t your father’s 100,000 BTU/h gas furnace. The blowers have significantly lower static pressure capability than what most HVAC folks are used to. My air handler allows the external static pressure to be selected at the controller (not by the homeowner) and the maximum is 0.36 inches. So ducts may need to be larger than you think if the distances are significant or there are a lot of fittings.9 – In cooling, the fact that these systems are variable-speed and have such a wide range of operating points means that oversizing appears to have little consequence (usually in a heating climate, the heat pump size is determined by the heating load, so the cooling ends up oversized). Our clients here on humid Martha’s Vineyard have been very pleased with these units’ dehumidification performance.10 – Minisplits are not yet drop-in replacements for fossil-fuel furnaces and boilers in conventional housing, but we’ve been applying them selectively in cases where the existing system is due for replacement. Surprisingly, from a source energy point of view they reduce carbon emissions. On one project, a single oil boiler heated and provided hot water to two adjoining homes totaling 7,500 square feet. It was replaced by three Daikin Altherma air-to-water heat pumps and two electric boilers (for severe weather – the Althermas hadn’t enough capacity, and more importantly, high enough temperature water at low outdoor temperatures). Annual electrical usage into the new system was just under 20,000 kWh. Oil consumption before the retrofit was 3,187 gallons/year, with associated CO2 emissions of 71,389 lbs/year. Using the EPA eGrid figure of 728 lbs CO2/MWh for the NEWE generation region, CO2 emissions dropped to 14,457 lbs/year, an 80% reduction. Fuel cost was reduced by 70%.11 – Ducted systems need well insulated ducts and they need to be airtight. My system has a design air flow of 353 cfm. Lose 100 cfm of that into the basement, and have ducts wrapped with bubble wrap, and half the output might not reach the living space. What we’d like to know more about1 – A consistent and understandable rating system for both capacity and efficiency. It’s frustrating to go to the AHRI Directory and find the heating rating at 17°F (the lower of the two rating temperatures) and then learn that the unit has a higher capacity at 5°F in the manufacturer’s engineering literature.2 – A good quick method for taking the HSPF and SEER ratings, assuming they can be made comparable and useful, and modifying them for different climates. I know how the machines we’re using in New England work, but I can’t tell you much about what to expect in substantially different climates.3 – A rating that includes how much power the system draws on standby, when the thermostat is satisfied. We’ve measured some surprisingly high wattage, and inquired of the manufacturer, to be told that we’re measuring improperly and that because of very low power factors the actual power draw is much lower. I don’t think we really know.center_img MARC’S ONLINE COURSE Interested in learning more?

Aggressive drivers want to take advantage of driverless cars

first_imgAggressive drivers are excited for the outbreak of autonomous cars on public roads, seeing it as a way to bully computers that err on the side of caution, according to new research.The London School of Economics and Goodyear conducted one of the largest surveys to gauge attitudes towards autonomous cars, with 12,000 drivers in 11 countries polled.See Also: Most Americans say they’re ready for an autonomous futureOne of the key findings was aggressive drivers expect autonomous cars to try and accommodate all types of drivers. In a situation where the self-driving system is unsure of the outcome, drivers expect Google, Uber, and Tesla to build systems that avoid accidents at all costs.“I’ll be overtaking all the time because they’ll be sticking to the rules,” said one driver in the survey. “They are going to stop. So you’re going to mug them right off. They’re going to stop and you’re just going to nip round,” said another.Across Europe, U.K. drivers have the most negative view of autonomous cars, according to the survey. 55 percent of U.K. drivers said they were uncomfortable sharing the road with an autonomous car, and 83 percent were concerned the car might malfunction.That’s higher than the average for non-U.K. nations polled, at 39 and 71 percent, respectively.Driverless tech still looking for on ramp anywayAutonomous cars are still an emerging technology that is only available on certain public roads, in certain cities. The U.K. and Germany are leading the race in Europe, followed by France, which recently endorsed some autonomous car tests on public roads.Outside of Europe, the U.S., Singapore, and China are the main hubs for self-driving tests. Baidu, Tencent, and Alibaba are all funding tests, either directly or through startups.In Singapore, nuTonomy, a MIT spin-out, has begun shuttle tests, with a goal of launching the service in 2018.
