ESE World Ltd – European manufacturer of temporary storage systems for waste and recyclables – will officially launch its latest waste container, the Split-Bin, at Letsrecycle Live on 15-16 September.

The 80-year-old firm will be using one of the waste and recycling industry’s biggest events to introduce its newest product to the UK market – a 240-litre-capacity, single container with a dual-stream capability, aimed at councils and waste management companies that run municipal contracts for kerbside collection containers.

The product has already been successfully applied in Denmark and is designed to reduce the contamination of recyclates.

Commenting on the new technology, ESE’s managing director, Peter Vernon, said: “With this kind of bin, the quality of the recyclate yield is higher, which not only attracts a greater return on investment, but only one collection vehicle is needed with one bin tip, meaning companies don’t have to buy – or replace – multiple caddies.

“Material contamination is a big bone of contention within the industry – and we need to innovate to bring new solutions which help to tackle this issue.

“Our Split-Bin allows larger volumes of different materials to be easily stored and separated – when compared to their individual box counterparts – and also reduces the collection rate, lowering CO2 emissions and fuel costs.”

The bin’s lid is designed to fan out when tipped – ensuring waste doesn’t get trapped when being emptied.

Peter continued: “While this type of waste storage equipment is widely used across Europe – especially in Scandinavia – there aren’t any like this model in the UK at the moment.”

Peter also believes that the country’s recycling rates would also be more likely to increase if UK councils were to adopt a one-system approach.

“Many local authorities use boxes or caddies instead of bins for recyclables – which can be lost or damaged more easily, when compared to a wheeled bin. There’s also no manual handling of the waste or lifting of separate containers, so truck operatives are at less risk of injury,” he concluded.

As well as launching the Split-Bin at the Letsrecycle Live exhibition in Stoneleigh, ESE will also be hosting a ‘guess the bin weight’ competition for attendees to take part in – the firm can be found at stand O2.

The news of ESE’s upcoming Split-Bin launch follows the recent announcement that the company has been shortlisted in Letsrecycle’s ‘Excellence in Innovation Awards 2021’.

ESE is also an organisation that possesses The Blue Angel ecolabel – meaning all its recycled solutions can have a minimum of 80% post-consumer resin – and it employs a closed-loop model for its products, collecting end-of-life containers for reprocessing into more units.

TotalEnergies, the Iraqi Ministries for oil and electricity, and the country's National Investment Commission have signed, in the presence of the Prime Minister of Iraq, major agreements covering several projects in the Basra region, designed to enhance the development of Iraq's natural resources to improve the country’s electricity supply. Iraq, a country rich in natural resources, is indeed experiencing electricity shortages while it faces a sharp increase in demand from the population.

2021 07 28 124820TotalEnergies, with the support of the Iraqi authorities, on the one hand will invest in installations to recover gas that is being flared on three oil fields and as such supply gas to 1,5 GW of power generation capacity in a first phase growing to 3 GW in a second phase, and, on the other hand, will also develop 1 GWac of solar electricity generation capacity to supply the Basra regional grid.

These agreements include:

  • The construction of a new gas gathering network and treatment units to supply the local power stations, with TotalEnergies also bringing its expertise to optimize the oil and gas production of the Ratawi field, by building and operating new capacities.
  • The construction of a large-scale seawater treatment unit to increase water injection capacities in southern Iraq fields without increasing water withdrawals as the country is currently facing a water-stress situation. This water injection is required to maintain pressure in several fields and as such will help optimizing the production of the natural resources in the Basra region.
  • The construction and operation of a photovoltaic power plant with a capacity of 1 GWp to supply electricity to the grid in the Basra region.

These projects represent a total investment of approximately $10 billion (100% share).

“These agreements signal our return through the front door to Iraq, the country where our Company was born in 1924. Our ambition is to assist Iraq in building a more sustainable future by developing access to electricity for its people through a more sustainable use of the country’s natural resources such as: reduction of gas flaring that generates air pollution and greenhouse gas emissions, water resource management and development of solar energy,” said Patrick Pouyanné, TotalEnergies' Chairman and CEO. “This project perfectly illustrates the new sustainable development model of TotalEnergies, a multi-energy Company which supports producing countries in their energy transition by combining the production of natural gas and solar energy to meet the growing demand for electricity. It also demonstrates how TotalEnergies can leverage its unique position in the Middle East, a region where the lowestcost hydrocarbons are produced, to gain access to large-scale renewable projects”, he added.

TotalEnergies in Iraq

In Iraq, TotalEnergies started its activities in the 1920s with the discovery of Kirkuk field. In the 1970s, TotalEnergies brought the Buzurgan and Abu Ghirab fields on stream. The company currently has a 22.5% interest in the Halfaya oil field producing approximately 20,000 barrels per day (TotalEnergies’ share) in 2020.

TotalEnergies sells lubricants in Iraq through distributors on the local retail market. Our affiliate Saft takes part in calls for tender as a subcontractor.

The latest Floating Liquefied Natural Gas (FLNG) project of the Malaysian oil and gas company PETRONAS (PFLNG DUA) has selected BASF’s OASE® purple for its Acid Gas Removal Unit process. This is the first FLNG reference worldwide for BASF’s OASE Gas Treatment technology. Together with PETRONAS and the Japanese engineering partner JGC Corporation, PFLNG DUA has been successfully started up in February 2021 and completed its Performance Test Run in May 2021. The floating LNG facility opens a new source of supply for cleaner energy as it is designed to extract natural gas from deepwater gas reservoirs in depths up to 1,500 meters.

OASE purple is an amine-based solution that is utilized for the removal of acid gases such as carbon dioxide (CO2) and hydrogen sulfide (H2S) from natural gas. The removal of acid gases is necessary to prepare the gas for the liquefaction and subsequent pipeline transportation. The highly efficient and environmentally friendly BASF-technology provides flexibility and low capital expenditure (CAPEX) for its customers. Additionally, the low energy demand of the process combined with the non-corrosive nature of the solvent keeps operating and maintenance costs (OPEX) low. The process also provides a high level of gas purity and product gas recovery while keeping solvent losses to a minimum.

An innovative corrugated bin for face masks by Metsä Board, part of Metsä Group, has been awarded a ScanStar in a Nordic packaging design competition organised by the Scandinavian Packaging Association. The mask bin, made of lightweight and durable corrugated board, helps to collect and dispose of used face masks easily and safely. Metsä Board developed the concept together with packaging design agency Futupack and corrugated board converter Capertum.

The competition jury commented: “A simple but clever solution for a new problem – mask littering. The bin is made from corrugated material, and is easy to assemble even without the instructions which have been printed on the bin itself. The lid makes the light packaging more rigid and, if you turn the lid, it closes the package when it is full. Good printing supports the product. The bin is also accessible to those who have disabilities.”

2021 09 01 131445

“The Covid-19 pandemic has brought its own challenges to waste management and together with Futupack and Capertum we wanted to develop a solution to this. In our design, we paid special attention to the lightness of the material, its durability and the ease of use and consumer guidance,” said Ilkka Harju, Packaging Services Director EMEA and APAC at Metsä Board.

MetsäBoard Pro WKL 160 g/m2 coated white kraftliner was used as the top liner of the mask bin. The Finnish corrugated board converter Capertum printed the E-flute corrugated board in silk screen. Thanks to fresh fibre board the waste bin is strong but light, which reduces the carbon footprint.

The University of Konstanz has reached an agreement with a German equipment manufacturing company on the protection of patent rights relating to their patents on LID regeneration of solar cells. With the support of TLB GmbH from Karlsruhe, Germany, a mutually beneficial agreement was reached. The foundation for this was laid by a successful  lawsuit for patent infringement. As a patent exploitation agency, TLB will continue to step up enforcement of the University of Konstanz's property rights and take legal action against further infringements. The basic intellectual property rights for LID regeneration held by the University of Konstanz have already been granted for years in the most important industrial nations and regions such as the USA, Europe and China.

"The protected method has been and is being used for the treatment of probably all boron-doped monocrystalline PERC solar cells. Therefore, it is a billion-dollar market in global terms," explains Dr.-Ing. Hubert Siller, Managing Director of TLB GmbH. It is a method that supports increase the efficiency of monocrystalline solar cells, which are mainly produced on the basis of the Czochralski (Cz) technique. Under operating conditions, however, the boron-doped CZ solar cells suffer from so-called light-induced degradation (LID), due to which the efficiency of a CZ-silicon solar cell is considerably reduced after only a short period of exposure to solar radiation. Depending on the material and production process, this can lead to a loss in efficiency of more than one percent absolute.

2021 09 01 121448

Scientists at the Photovoltaics Department of the University of Konstanz introduced as early as in 2006 a method to neutralize this type of degradation. The process developed and optimized over years by Axel Herguth, Svenja Wilking and Professor Giso Hahn can easily be integrated into the production process. The scientists made use of the fact that the degraded solar cells can be regenerated by exposing them to light energy greater than 100 degrees Celsius. Alternatively, regeneration can also be achieved using electrical current instead of lighting.

The economic potential of regeneration is enormous: If the degradation-caused loss in efficiency of one percent absolute is nearly completely offset, this yields additional efficiency of approx. five percent. With a 1 GWp production line, we are looking at over ten million euros per year. Another major advantage is the resource conservation that can be realized by regeneration. A higher level of efficiency means that less raw materials and energy are consumed, which in turn leads to a more environmentally friendly production. Operators of solar plants thus benefit from higher yields and end consumers from lower energy costs.
