Converting Mixed Waste into Raw Materials

The Netherlands:

 

The facility will be the first of its kind in Europe to provide a sustainable alternative solution for non-recyclable wastes, converting waste plastics and other mixed wastes into new raw materials. 

A consortium of companies comprising Air Liquide, Akzo Nobel Specialty Chemicals, Enerkem and the Port of Rotterdam has signed a project development agreement covering initial investments in an advanced waste-to-chemistry facility in Rotterdam.

Bulk Bag Conditioners for Bag Discharging

 Bulk bags (or FIBCs) have increased in popularity significantly over the past few decades due to the reduction in packaging and transportation costs. However as more companies move and store materials in bulk bags, some struggle to discharge agglomerated or hardened solid material.

In particular where bulk bags contain material such as hygroscopic chemicals, certain types of spice blends, heat-sensitive products and other materials prone to solidifying to the point where bulk bag dischargers are inefficient or completely ineffective, a bulk bag conditioner could be the answer.

A bulk bag conditioning system is an easy and effective way to break up solid ingredients, thereby increasing productivity. The system is also able to reduce operator costs and promote a safer working environment, and, with a relatively small equipment footprint, can minimise the use of valuable floor space.

Turecko má na svém území 4 % světových zásob nerostných surovin

Turecká ložiska nerud, tak jako všude na světě, lze rozdělit na silikátová a ostatní (v poměru 1:1). Mezi ta první patří kaolin, jíly, živec, attapulgit-sepiolit, bentonit, azbesty a nefelinický syenit. Těžby jsou v tisících tun (kt) v devadesátých letech v době útlumu po konci bipolarity světa, v závorce je těžba 1990 (před útlumem). Kaolin se těží u Sindirgi (prov. Bursa), 180 kt (250 kt), 18. místo ve světové těžbě. Ložisko Arnavutkőy (24 km sz. od Istanbulu) vzniklo zvětráním třetihorních andezitů podél tektonických linií SZ-JV, původně doprovázených hydrotermální sericitizací. Ložisko Kinik Sedikőy (prov. Kűtahya) obsahuje opál, což při použití ve výrobě papíru nevadí. Ložisko čistého kaolinu s výplavem 50 % a 0,12 % Fe2O3 Deresakarikőyu - Gőčűk (prov. Bilecik) má bohužel jen malé zásoby. Vzniklo zvětráním rhyolitového tufu. V roce 2001 se vyvezlo 211 kt kaolin.

Rare-earth elements discovered in U.S. coal basins


According to a February 2017 report from Zion Research, the global rare-earth metal market was worth nearly $5 billion in 2014 and is projected to reach $9 billion by 2020. China is currently the top country producing rare-earth elements. In 2016, it exported 32,500 metric tons of the 105,000 metric tons it produced.
 And the United States didn’t even make the list of the top rare earth producing countries last year. The U.S. Geological Survey tracks the U.S.’s net import reliance for mineral commodities every year. In 2016, the U.S. was fully reliant on foreign countries for 20 mineral commodities, including rare-earth elements (REEs).
 Rare earths are crucial in the manufacture of high-tech devices—computers, rechargeable batteries, cell phones, cameras, magnets, aircraft engines, and more. The only rare earth mine in North America closed last year, leaving the U.S. completely reliant on imports.

Controlling fugitive dust at a limestone conveyor transfer

A global provider of quicklime and chalk products has resolved a significant fugitive material problem by implementing state-of-the-art containment and dust suppression on one of its primary limestone conveyors.

 
After finding that an estimated 10 – 20% of the material load was spilling along the belt path, Singleton Birch implemented a control strategy from Martin Engineering that included a rebuilt transfer point as the material takes a 20 ft drop from one belt to another. Once the upgrade was complete, the air inside of the conveyor enclosure was clear enough to see down its entire length, with dust management so complete that at first remote operators questioned whether the material flow had resumed or not.

Bulk flow measuring in the cement industry

   Every application and every process is different. In order to define the correct technology and the right instrument it is essential to analyze all different process parameters such as material properties, process temperatures, process pressure, process connections as well as the material of the silo or vessel.

 
   The efficiency of an industrial plant is not only influenced by its mechanical and electrical installations, the appropriate planning, selection and engineering of the required overall infrastructure also play a critical role. Viewed as an integrated entity, the plant’s infrastructure also includes items like optimized measurement technology. The selection of the right technologies, their correct configuration and smart positioning will save substantial costs and add up to a significant improvement in the plants’ economic efficiency over its lifecycle.

Will IT BE ENOUGH?

Li SUPPLY PIPELINE IS FILLING 
   The electric vehicle revolution is gathering momentum.Barely a week goes by without a fresh, starting revelation, whether it be Sweden’s Volvo promising to phase out traditional internal combustion engines from 2019 or France aiming to end the sale of gasoline and diesel vehicles by 2040.And, of course, leading the electric charge is the poster child of the green technology revolution, Tesla, which is gearing up to roll out its Model 3, the long-awaited break-out from niche to mass market.

MINDING THE GAP

  All of which may be good news for Tesla and its peers sitting at the other end of the supply chain but it would seem to bode ill for the countless junior miners aiming for a piece of the lithium action.
  The big three, or big four if Ganfeng is included, are understandably keen not to loosen their historic grip on the market even as it enters a period of potentially explosive growth. But those hoping to form part of a third, future supply wave shouldn’t lose hope. Because while supply appears to be firming up, demand remains a fast-moving, elusive part of the price equation.As recently as March this year SQM said it believed lithium demand “could grow over 10 percent per year in the near term”. Fast forward four months and it has lifted that estimate by four percentage points.

Selection and Configuration of Screening Machines

Screening technology is one of the oldest and most widely used technologies for processing bulk solids. And even though the principle of screening is actually “child’s play”, several factors must be noted when constructing industrial screening machines to make sure the screens work optimally later on during production. And like in many other production plants, it’s the material that’s to be screened which is at the center of concerns.
