“…The situation is likewise observable in the Netherlands, Poland and China. Repair rates are higher in East Asia-66% in China and 64% in South Korea-than in Germany (23%) and in the US (28%) [21,22]. In the Netherlands, 12% of the currently used phones are either used (second-hand/directly sold) or refurbished, and the most common used/refurbished phones are Apple IOS phones (19%), followed by LG (12%), Sony and Samsung (each 9%) and Huawei (4%) [23].…”

Circular Economy as a Glocal Business Activity: Mobile Phone Repair in the Netherlands, Poland and China

Repair of mobile phones fits with the vision of a circular economy in an urban context and with the Sustainable Development Goal 11 Sustainable Cities and Communities. Drawing on the literature about firm level competitiveness and closed-loop design through repair, remanufacturing or recycling, we analyze the business ecosystem of independent mobile phone repair shops in the Netherlands, Poland and China as a glocal business activity. The analysis is based on primary data collection through a questionnaire to independent repair shops in the Netherlands (n = 130), Poland (n = 443) and China (n = 175) with response rates of 13%, 12%, 40%, respectively; and 17 interviews in the Netherlands, 40 in Poland, and 70 in China. Findings indicate that to maintain a strong position in the local market and to sustain the trust of customers, independent mobile phone repair shops offer a range of customized services based on direct contact with customers. In China, the increasing prices of spare parts and falling prices of mobile phones constitute the most important challenges, whereas in the Netherlands and Poland, the most important challenges are the competitive pressures from informal repair activities, and new repair shops. Our research also revealed that repairability strongly depends on the global manufacturers’ circularity choices.

“…Different from the treated recycle networks in the literature [8,12,19], the recycle system shown in Figure 1 does not consist of the incineration plants, the landfill plants and the secondhand markets (outside the dotted line). These nodes of recycle network are only regarded as external factors of system such that the system is in accordance with the existent practical situations.…”

“…On the 9th February 2015, the latest "Directory of Waste Electrical and Electronic Products Processing" was enacted [5]. But even so, there are still many obstacles to develop Chinese WEEE management system, such as higher operating cost, weaker awareness of environmental protection, and imperfect incentive mechanism [8].…”

Recovery of waste electrical and electronic equipment (WEEE) plays an important role in protecting environment and conserving resources. Design of a more efficient WEEE recovery system is an imperative need for the relevant decision-makers, such as alleviation of overcapacity or insufficient recycling in many developing countries. In this paper, we optimize the WEEE recovery network which is associated with recycling prices and government subsidies by a nonlinear mixed integer programming approach. An integrated model is first proposed to formulate a design problem of WEEE recovery network, being involved with collection centers, two types of transfer stations, processing centers, incineration plants, landfill plants, secondhand product markets, and government subsides. The recycling prices and the transported quantities of WEEE (the number of batches) are endogenous variables of the model, being subject to a number of practical constraints. For solving this model, an algorithm is developed based on the branch and bound method. Scenario analysis and numerical experiments indicate that: (1) appropriate capacities of transfer stations can be provided by the proposed model for designing an environmentally and economically efficient WEEE recycling system, especially for alleviating the existing overcapacity or insufficient recycle. (2) An optimal governmental subsidy can be obtained in virtue of the proposed model and algorithm. (3) Diversity of transportation modes and permission of more than one mode in the same delivery route can greatly reduce the cost of recycling WEEE. (4) Preferred awareness of environmental protection can increase the profit and the recycled quantities, as well as reduction of the total recycling cost.

“…Due to the legislative pressure of producers and resellers to collect waste properly, the collection points should be as publicly adoptable as possible to maximise the collection rates (Gamberini et al, 2009) while addressing social issues such as hoarding of smaller devices for potential later use that is never realised. The final consideration refers to the public visibility of systems (Cao et al, 2016;Yla-Mella et al, 2015). With these considerations, decentralised collection systems are not primary processing points, but could assist in combining waste streams with reasonable pre-treatment (Salhofer, 2014).…”

<p>In Jordan and as in many other Mediterranean countries olive oil production is one of the major agricultural production, it is estimated that the annual production of olive oil in Jordan approximately 21.5 thousand tons per year. O the other hand the process of olive oil extraction generates around 200,000 m3 of olive mill wastewater (OMW) and it is considered as a a serious problem in. In this study the real sample of wastewater is collected from the outlet at the mill near by the university campus. The analysis of this collected wastewater has shown a very high Chemical Oxygen Demand COD (253.648 kg/l) and Bilogical Oxygen Demand, BOD (89.365kg/l). These high BOD and COD reveals a real need to treat it before sent to municipal sewage. The study also focuses on reducing an organ phenol component which has been measured and found equal to 0.5698mg/l. The use of Ferric Oxide in the form of nanoparticles was successfully used to oxide organic phenols from olive mill wastewater (OMW) and has reduced to 0.002 mg/l. The results show that 0.1g of Ferric Oxide in the form of nanoparticles when mixed with sand has the capacity to remove the phenols from the collected samples. The removal percentage obtained here reached 97%. When the mixture of ferric nanoparticles used with sand in a ratio of 0.1 g Fe2O3and 1 kg of sand, the removal capacity of organic phenols has reached to 99%, and COD () in percentage of 97.2%. The results show an interesting behavior towards other minerals that exists in solution, that ferric nanoparticles have a good capacity to remove Cr+3Cu+3 K+Ca+2Na+.minerals exist in wastewater.</p>
