ISO 14001 revision is underway

Over 250,000 organizations are certified to ISO 14001 and while it continues to be as relevant as ever, the revision will take into consideration a number of issues to ensure organizations are able to grow in a sustainable way.
All ISO standards are reviewed every 5 years to establish if a revision is required to keep it current and relevant for the marketplace. The future ISO 14001:2015 will respond to latest trends and ensure it is compatible with other management system standards such as ISO 9001. The new version will include a requirement to understand the organization’s context in order to better manage risk, with more emphasis made on leaders within organizations to promote environmental management. In addition there will be a shift towards improving environmental performance rather than improving the management system. ISO 14001 is currently at the Draft International Stage (DIS), the 4th stage of a 6 stage process, whereby anyone who is interested can submit feedback to the experts on the technical committee revising the standard.

paper : Smart self-healing coatings for corrosion protection

A paper gives a concise review on the most recent advances in preparing micro/nanocapsules for smart coatings: Smart self-healing coatings for corrosion protection of metallic substrates (steel, magnesium, and aluminium, and their alloys) have attracted tremendous interest due to their capability to prevent crack propagation in the protective coatings by releasing active agents from micro/nanocapsules, that is, micro/nano particles consisting of a coating layer or a shell (micro/nanocontainers) and core material (solids, droplets of liquids or gases), in a controllable manner. This paper aims to give a concise review on the most recent advances in preparing micro/nanocapsules based on different types of micro/nanocontainers, i.e., organic polymer coatings, inorganic clays, mesoporous silica nanoparticles, polyelectrolyte multilayers, etc. for smart coatings with self-healing properties. The state-of-the-art design and preparation of micro/nanocapsules are highlighted with detailed examples.

article : How to eliminate foam in Coating Formulations

Avoiding foam formation is a main concern in the paint formulation and application process.
Main causes of foam formation are stabilization of air in the liquid paint, due to the presence of surfactants. Depending on the size of the foam, macro-foam and micro-foam is considered. Macrofoam is visible at the coating surface layer, whereas microfoam is entrapped and distributed in the entire coating volume.
Foam formation effect the speed of the manufacturing process and may lead to various paint film performance defects, such as cratering, haziness, low gloss. Surfactants are present in a typical waterborne paint formulation as a component in the polymeric binder emulsion, in the biocide or as pigment wetting agent, thickener or various other paint components.
A practical way to avoid foam formation is the use defoamers. A wide range of products are available. This article addresses to the chemical composition and working mechanism of main defoamer classes, such as oily versus polysiloxane based defoamers and is explained in detail.

STYRON Europe increases polystyrene prices

STYRON Europe will seek to increase general purpose and high-impact polystyrene prices in January by Eur110/mt ($143/mt), the company said. The price increase responds to the rising costs associated with the manufacturing of polystyrene grades in Europe, according to STYRON. Styrene producers lost quite a bit of margins in December and STYRON shut both its styrene facilities at Bohlen and Terneuzen on poor economics.
The styrene/benzene spread in December has hovered at around $93-130/mt or $120-207/mt below the required breakeven spread of $250-300/mt for regional producers, depending on energy costs and how efficient the plant is. In contrast to this, the naphtha-benzene spread (a measure of benzene profitability), hit a six-month high of $588.50/mt on December 28, compared with the June 13 level of $586.75/mt. The styrene-over-benzene spread dipped below $200/m.t. in the European market on 7 January and today for only the second time since September 2014.
Europe's styrene-benzene spread dips below $200/m.t. Falling energy numbers have been pressuring absolute spot values for styrene and benzene, but this most recent squeeze indicates that styrene in Europe can no longer shrug off the combined forces of improved supply and weak downstream fundamentals. A sub-$200/m.t. level indicates margins in or close to negative territory and last occurred just prior to the force majeure declaration at Shell's Moerdijk, Netherlands.

SIKA reports record sales

Sika AG reported record sales in every region and also says that all relevant growth targets for full-year 2014 have been exceeded. An above-average increase in net profit is expected for the business year 2014. In the fourth quarter of 2014, Sika's consolidated net sales rose by 5.1%. Sales for full-year 2014 rose by 13.0% to CHF 5.57 billion. Sika thus significantly exceeded its growth targets. All regions contributed to this growth and set new sales records. The negative currency effect for the full year was -4.7%. Sales in Swiss francs increased by 8.3% after adjustment for currency effects. Sika CEO Jan Jenisch: "We exceeded our growth targets not only in the last quarter of 2014 but also throughout the entire financial year". Sales in the region EMEA (Europe, Middle East, Africa) increased by 13.3% in the year under review. Visible growth drivers in the Middle East and Africa and the moderate recovery seen in the southern European markets had a positive impact on the region's development.

CPI to transform food waste into Graphene

It is estimated that 90 million tons of food is wasted in the EU each year, a figure which could rise to approximately 126 million tons by 2020. The Centre for Process Innovation (CPI) is leading a European collaborative project that aims to transform food waste into a sustainable source of significant economic added value, namely graphene and renewable hydrogen. The project titled "PlasCarb" will transform biogas generated by the anaerobic digestion of food waste using an innovative low energy microwave plasma process to split biogas (methane and carbon dioxide) into high value graphitic carbon and renewable hydrogen. The sustainable creation of graphene and renewable hydrogen from food waste in provides a sustainable method towards dealing with food waste problem that the European Union faces.

paper : Anticorrosive nanoferrite dispersed WB epoxy-acrylate

Waterborne epoxy acrylate-butylated melamine formaldehyde coatings and ferrite dispersed nanocomposite coatings have been developed, with a view to effectively replace the hazardous solventborne polymeric coatings with anticorrosive properties. Ferrite nanoparticles in matrix act as filler, which fill the pinhole, interstitial crosslinked spaces and other coating artifacts (micro cracks and voids) regions besides provide strength to the coating material. Electrochemical studies revealed that the coatings were found to be effective in restricting the penetration of aggressive ions by forming a strong barrier layer at coating metal interface.

PPG's results beat estimates

PPG Industries today reported fourth-quarter net income from continuing operations of $86 million, down 64% year-on-year (YOY), on sales up 6%, to $3.71 billion. Increasing volumes drove the results. "While overall global economic activity remained modest, our sales volumes improved about 4%, with each major region delivering volume growth at or above our third quarter results. This was aided by solid growth in each business in our industrial coatings segment, along with continuing sales improvement in aerospace and automotive refinish", says PPG chairman and CEO Charles Bunch. PPG is mostly optimistic about 2015: "As we enter 2015, we anticipate growth rates will remain mixed by region, with North American and Asian economies continuing to grow at rates generally consistent with 2014. Our base case assumption is that European growth will remain mixed by country but subdued overall. However, we believe that European economies stand to benefit considerably if oil prices remain at current levels, which may stimulate higher growth in that region", the CEO says.
