25 June 2008South African paper and pulp company Sappi is increasingly using biomass recovered from wood and bark waste instead of coal to generate thermal energy and steam to power operations at several of its mills.The move has allowed the company, which is one of the leading producers of coated fine paper in the world, to cut down on industrial coal usage – South Africa’s main source for carbon emissions – as renewable resources now provide just over 40% of the company’s energy requirements.“As responsible corporate citizens in an energy-intensive industry, one of our primary goals is to reduce our carbon footprint by decreasing our reliance on fossil fuels,” said Sappi CEO Ralph Boettger in a company statement earlier this month.Despite South Africa’s overall contribution to world carbon emissions only standing at 1.6%, the company points out that by ranking as the 11th highest carbon emitter in the world, the country has to take the impact of its industries on the environment seriously.In addition, Sappi adds that South Africa’s overall emissions had increased by 30% over the last decade.“Sappi’s consumption of electricity and the nature of its manufacturing make addressing its energy use essential,” the statement read. “Through the use of alternative production methods, the company is on its way to a more eco-friendly and sustainable business.”Clean Development MechanismIn 2007, Sappi stepped up it replacing of coal with biomass recovered from the wood and bark waste that results from the debarking and chipping in the operations at several of its mills.In the same year, the company registered South Africa’s sixth Clean Development Mechanism (CDM) project with the United Nations. The project involved converting the number 10 boiler at Sappi Tugela Mill to enable co-firing of bark as biomass with coal to generate thermal energy and steam.The project has resulted in a net reduction of fossil fuel greenhouse gas from coal firing, a reduction on landfill usage and resulting methane emissions and also a reduction in the impact of transporting coal from Mpumalanga to KwaZulu-Natal by road and rail.By making use of resources readily available to them, Sappi is able to save 53 000 tons of coal that would have been used in place of the biomass per year.‘Kicking the habit’“With the AmaKhulu project upgrade at the Sappi Saiccor Mill, we have also increased the rate of recovery of wood solids for use of steam-run power at this mill,” said Boettger. “All these initiatives will contribute in reducing greenhouse gas emissions responsible for global warming.”The company said it was essential that as a developing country, South Africa was able to kick the CO2 habit through its industrial production, by developing more environmentally friendly processes that would allow for a better future for Africa in which its delicate eco-systems were unaffected by human waste products.“Developing these sustainable methods is not only up to one or two organisations, but also up to each individual and company to make the overall difference,” the statement reads. “After all, the more we preserve the resources we have now, the less likely we’ll be to run out of them in future.”SAinfo reporter Would you like to use this article in your publicationor on your website?See: Using SAinfo material
23 April 2013 South Africa’s largest privately owned defence and aerospace firm, Paramount Group, has won an international bid to supply security vehicles to Brazil, the company announced last week. It will supply its Maverick security vehicles, which have been designed to be used by security forces. The Maverick vehicle will be used by Brazil’s special police operations battalion and its shock police battalion, which is part of the country’s military police and special resources battalion. “Sharing defence and security equipment represents a new level of international trade cooperation, and this announcement not only demonstrates strengthened alliances between Africa and Brazil but the unity of the BRICS alliance,” Paramount chairperson, Ivor Ichikowitz, said in a statement. The deal is expected to help the country deal with security concerns for the hosting of the 2014 Fifa World Cup and 2016 Olympic Games. “The equipment to be supplied by Paramount Group will play a critical role in the security infrastructure for both these events,” Ichikowitz said. “Paramount Group is very proud to have been selected to support the government in this important role and is looking forward to being part of the growth of this dynamic country.” The awarding of the contract came after intensive technical evaluations, field testing and a procurement process open to local and international companies, Ichikowitz said. “South Africa has a proud heritage in the defence and security sector and Paramount Group is continually investing in research and development thus ensuring its products are at the leading edge of technology,” he said.

Role of Mobile App Analytics In-App Engagement What it Takes to Build a Highly Secure FinTech … CHARGE Anywhere, a mobile payments company and gateway provider, has introduced a system that enables the Google Nexus S phone to function as an NFC-enabled mobile payments terminal. Using a mobile application downloaded to the device, merchants can accept NFC payments using just their Nexus S smartphone. An optional printer and swiper enables merchants to accept traditional credit card payments as well. NFC & Traditional Payments AcceptedWith its mobile payment platform for Android, shown off at last week’s CTIA conference in Orlando, Florida, CHARGE Anywhere is making a name for itself in the growing mobile payments space that includes competitors like VeriFone, Square and Intuit. With CHARGE Anywhere’s system, merchants can accept NFC-enabled payments, such as those from MasterCard’s PayPass and Visa’s payWave (both contactless payment systems), using only their mobile phone.For traditional credit card processing, the company also provides a combination card swiper and receipt printer which connects to the mobile application over Bluetooth. Printer/swipers are available for Android, BlackBerry, iPhone and iPad devices while an optional audio jack swiper and sleeve are available for the iPhone only.By Q2 2011, CHARGE Anywhere plans to add PayPal support to its application to supplement the payment methods it accepts, which now include Cash, Check, Credit, Gift/Loyalty cards and ACH/eCheck payments.The benefit of using the CHARGE Anywhere solution, says the company, is that a merchant can bring their own account from their own bank to the service, instead of having to drop that and sign up for a new one. The company supports all major card processors and allows its transactions to be uploaded into QuickBooks.Other AppsThe new Android solution is being made available as a software update to the Android application already available in both the official Android Market and the Amazon Appstore for Android. CHARGE Anywhere has its software in other app stores too, including iTunes, RIM’s BlackBerry App World and the Windows Marketplace (for Windows Mobile; a Windows Phone 7 version is in the works). JME and Brew versions are available as well, with the Brew version arriving in Verizon’s VCast apps store soon.NFC, or near field communications, is an emerging technology that allows for short-range, wireless data transfers between two devices, such as a mobile phone and a point-of-sale system. Google is reportedly working on its own mobile payments system with Citigroup and MasterCard, according to a new report out today. Other initiatives in the U.S. include Isis, a carrier-led NFC payments system with Discover and Barclay Card as partners and Visa’s In2Pay, which enables NFC transactions on a number of mobile devices through the use of microSD cards either inserted into the phone itself or into a case for the phone. sarah perez Why IoT Apps are Eating Device Interfaces Tags:#mobile#news#web The Rise and Rise of Mobile Payment Technology Related Posts
_This podcast series is excerpted from a two-day class called “Building Science Fundamentals” taught by Dr. Joe Lstiburek and Dr. John Straube, of Building Science Corporation._ For information on attending a live class, go to BuildingScienceSeminars.com In our last episode, Dr. John Straube argued that building energy-efficient buildings takes just a little extra thought but makes economic sense. In this show, Dr. Joe Lstiburek offers a simple comparison between air barriers and vapor barriers, and warns that we need to worry more about airtightness if we want to keep our homes healthy and dry. __________________________________________________ Smaller holes mean less moisture in your wall You have to understand the difference between air and vapor. Vapor barriers can be ripped and torn and full of holes because the amount of water vapor that passes through due to diffusion is very small compared to the amount of water that can go through a hole or a crack due to an air pressure difference. I can move air, and if that air moves and there’s vapor in it the air will carry the vapor with it. For that to happen I need a hole and an air pressure difference. The likelihood of having a hole is very high. And the likelihood of having an air pressure difference is even higher. So it behooves us to get rid of as many of the big holes as possible, and try to get as many of the small holes as well, but at the end of the day we’re still going to have some holes. It also means we ought to reduce the air pressures as much as we can, but at the end of the day we’re still going to have some air pressure differences. No matter how good we are, some vapor’s going to be carried by air as a result of a pathway and a pressure difference. Now let’s put that aside. Diffusion moves much less water than air leaks If I have no holes, and I have no air pressure difference, but I have vapor on one side and I don’t have much vapor on the other side, I’m going to have a vapor pressure difference. And that material, depending on how easy it is for the water molecules to burrow through, will pass the water molecules. We call that vapor diffusion. Gypsum board is very vapor-open, so a lot of water will diffuse through it in the vapor form. But gypsum board is a fantastic air barrier. So if I installed gypsum board on the inside, and if I taped all of the joints together, and I had no windows — in other words a gypsum board box with five sides on a concrete slab, and I just caulked the bottom edge of the gypsum board to the slab — I would have a wonderful air barrier system. And I would have absolutely no moisture carried by air transport. Now here’s the rub: the vapor transport is negligible compared to cutting a one-square-inch hole in that box and having just a modest air pressure difference between the inside and the outside. So what’s more important in controlling moisture transport? Air tightness. Now for the vapor tightness I could enclose maybe 90% of that enclosure with paint, which would be a vapor retarder. And the 10% I didn’t get — who cares? I’m reducing 90% of a small number. So I don’t really care if my vapor control layer is continuous because it doesn’t move that much moisture. But it’s real important that my air control layer is continuous. So air barrier continuity is much more significant that vapor barrier continuity. Vapor barriers still work if they have holes in them Now where it get’s real exciting, and interesting to me, is a concrete slab. So let’s say I’m putting 4 inches of concrete on top of the ground, and before I pour it I put down a plastic sheet — that sheet will be my vapor barrier. So let’s say before I pour my concrete I walk on the plastic sheet with golf shoes for about two hours. So what’s the total surface area of the punctures compared to the total surface area of the plastic? If I’m there for about two hours, maybe it’s 10%. So I basically have reduced the vapor control layer effectiveness of that plastic sheet by 10%. Vapor flow by diffusion is a direct function — it’s linear. Airflow is not; it’s an exponential function of pressure. But let’s go back to the slab for a moment. What am I going to put on top of that ripped and torn and punctured plastic? Well, 4 inches of concrete. Concrete is a pretty good what? Air barrier — and it’s also a darn good vapor retarder. So I haven’t increased, even from a measurable perspective, the amount of water vapor transmission from the ground into the floor with the ripped and torn plastic sheet. That’s why I always laugh at the people that say, “Well, you gotta tape the joints and you gotta be careful not to puncture it.” Give me a break! Now I don’t go out of my way to tell people to rip and tear it, and puncture it and leave gaps in it. And if they’re going to the trouble to tape the joints I’m not going to tell them, “Don’t go there.” It’s just not something I’m going to get bent out of shape about if they do a lousy job. Know when your vapor barrier is also an air barrier Now, what would happen if I took that concrete off of the plastic, and now I have a conditioned crawl space, and the only thing I have separating the ground from the inside of my house, which is the air in the crawl space, is a ripped and torn plastic sheet? Well, now I have a problem — because that sheet was supposed to also act as an air barrier. Now the amount of water vapor that goes through that plastic by diffusion is still very small, but the amount that will be carried as a result of air flowing across those rips and tears is huge. It’s typically 2 orders of magnitude — that would be a factor of 100. So that’s why we really care about air barriers, but we don’t care a hell of a lot about vapor barriers.
