    Charcoal Briquettes or Lump Charcoal?

    Charcoal Briquettes or Lump Charcoal? This article is not talking about cooking with gas and cooking with charcoal. I’m also not going to discuss the differences between grilling and barbecuing. What I really want to talk about is charcoal. More specifically, charcoal briquettes vs. lump charcoal. Back in the day, my father always used charcoal briquettes, and for years I did the same. But about two years ago, my BBQ buddy convinced me to make the switch over to lump charcoal. And yes I did, until I actually did the research to write this. So, since doing a little research, I’m back to my old fondness of briquette charcoal. But…

    Coconut Charcoal

    Coconut shell charcoal is made with a process begins with the carbonization by burning the coconut shell with controlled air that is sufficient for carbonization. The output of charcoal in the traditional pith method is just below 30% yield. To obtain good quality charcoal, fully dried, clean, only mature shells are used. Coconut charcoal is then sieved to the different sizes that the buyer requires. Coconut charcoal briquette is a compact block charcoal made from coconut shell charcoal. Charcoal briquette is made of granular coconut shell charcoal that is crushed charcoal and molded using a natural binder. As fuel, it burns hotter and lasts longer than other charcoal. It is…

    Coconut Shell Based Activated Carbon

    The use of activated carbon to remove harmful impurities like organic contaminants from water has been practiced since Roman times. Activated carbon is a carbonaceous adsorbents with extensively developed internal pore structure. Activated carbon is extremely porous with a very large surface area, which makes it a powerful adsorbent material. This large surface area relative to the size of the actual carbon particle makes it easy to remove large amounts of impurities in a relatively small enclosed space. An approximate ratio of surface area is one square meter per gram. The two mechanisms by which the chemicals are adsorbed onto activated carbon are either it ‘dislikes’ water or it attracts…

    Indoor air quality sensors in your smartphone

    Indoor air quality can be as much of a health concern as the air quality outdoors. Things like volatile organic compounds (VOCs), carbon monoxide, mold and other compounds can cause things like headaches, fatigue, respiratory illnesses and worse. The EU has started to focus on how to combat indoorpollution and is funding a new project that would allow people to have real-time air quality information wherever they are — at home, at work, even in the car. The project aims to “develop new nanotechnology-based sensor systems that will precisely monitor the composition of the air in terms of both chemical and bio contaminants.” It is designed to be both tiny and low cost so that…

    A “Salty” Restaurant that Cleans Air

    When we think of salt, we think of it as a seasoning. But for an Iranian restaurant group, salt was the main material for a new kind of eco-friendly building. The “Salt” Restaurant of Shiraz is located in the southern Iran, where the walls, tables and even the stairs were covered with a salty coating. To our surprise, this layer of salt helps clean the polluted air of the city. Inspired by local and naturally occurring salt caves of the region, the group wanted to create a design that reflected the area’s distinctive salt mines and Marharloo salt lake of Shiraz. They stated, “In this particular case, the walls, structural…

    Is A Day-Old Water Safe To Drink?

    Have your tried water that’s been left overnight, or even for another day? How do you think about the taste? Treated water’s added chlorine that takes care of microorganisms, but at room temperature they begin to multiply rapidly and can really get the things crazy. But that’s not what makes old water taste stale. For that we can thank carbon dioxide. After about 12 hours tap water starts to go flat as carbon dioxide in the air starts to mix with the water in the glass, lowering its pH and giving it an off taste. But it’s most likely safe to drink. However, back to those microorganisms. Be careful if…

    Make Your Cleaning Routine Green

    Cleaning products are everywhere in our homes and offices: on dishes, furniture, clothes, floors, windows, and floating through the air. This may sound bizarre, but in our war on dirt and germs we may often actually be making things worse. Most of the conventional cleaning products we all grew up with are petroleum-based and have dubious health and environmental implications. Instead of opting for cleaning products that annihilate everything in their path, there are plenty of natural products and methods that keep a house clean and fresh without the toxic side effects. Employ green cleaning products As conventional cleaning products have become more thoroughly investigated, more and more brands of…
