Glencal technology Co., Ltd. successfully developed the RedoxMaster technology which can dry organic matters very rapidly at low cost and low temperatures, without carbonization and oxidization. We hope to contribute the sustainable economy where environmental protection and economic growth coexist by applying the advanced drying technology to various areas.

Glencal technology Co., Ltd. was set up in 2013 to specialize environment businesses. It evolved from Glencal Co., Ltd, which was established in 2002 and has been engaged in investment, M&A advisory services, and consulting services in various fields such as medical and environmental industries. In the last decade, Glencal Co., Ltd has been increasingly dealing with the environment-related businesses, including investment in green business, supporting management of these businesses. Through these activities, we found that excellent environmental technologies invented in Japan have not been monetized because of various causes. We thought it is more important for us to develop and productize these technologies rather than just to invest and consult these businesses. That is the reason why we set up Glencal technology Co., Ltd. in December 2013. Since then we have developed and productized the RedoxMaster technology which can dry organic matters very speedily at low cost, while avoiding oxidization and carbonization.

The core competence of our company is needles to say that we own the RedoxMaster technology. In addition to that, the various expertise and high-end domestic and global networks that Glencal Co., Ltd has built through investing and consulting businesses are also our strengths which make us distinguished from other competitors. Our mission is to improve the environment of the world by utilizing our cutting-edge RedoxMaster technology and our unique competences.

Our business model

Basically, we do not sell RedoxMaster to clients. (There are some exceptions with some of public or semipublic organizations.) After discussing with prospective partners regarding terms and conditions such as the purpose of the joint project and so on, we produce a customized model of the RedoxMaster. In many cases, the machine is installed at the partner's factory.

The joint project among the client, Glencal Technology and other related parties dry organic matters, and sell the residue processed by RedoxMaster as value added material for biomass plastic, fodders, fertilizers, fuel pellets and supplements. That is our business model. This business model is applicable in any areas where drying treatment is necessary. Successful cases are introduced in the following section.

Apple juice factory
JA Aoren

JA (Japan Agricultural Cooperative) Aoren (in Aomori prefecture) is one of the largest apple juice factories in Japan, as Aomori prefecture produces a vast majority of Japanese apples. One unit of RedoxMaster is installed inside the factory. We treat apple juice pomace by RedoxMaster and process the residue into materials of value added livestock fodder and biomass plastic. As RedoxMaster can dry organic substances below 100℃, the drying cost is extremely smaller compared to conventional methods. The energy cost is much cheaper at Aoren, as the waste heat of the existing boilers can be used as auxiliary heat source. The precious polyphenol in the apple pomace is not damaged after the treatment, as RedoxMaster treat them at low temperatures. The water content ratio of the residue is below 15%, therefore, it can be storable for a long period. Also, the weight is reduced, the transportation cost is cheap to carry those materials to fodder companies and bioplastic factories.

It has been proven that the fodder with a small amount of the apple pomace residue treated by RedoxMaster increases the palatability of cattle, and the quality of meat improves. JA Aoren and Glencal Technology make profit by selling the processed apple pomace to livestock feed manufacturing companies.

Coffee ground project subsidized
by Aichi prefecture

The project which won the environmental business competition for the Aichi prefecture's subsidy aims to produce materials of bioplastic and animal feed from coffee ground generated from a multinational beverage factory in Aichi prefecture. Our RedoxMaster is used to dry the wet coffee ground rapidly at low cost without damaging the nutrients and energy in the coffee ground. Recently, the problem of plastic waste has been the hot topic all over the world, and the regulations to reduce the consumption of petroleum plastic have been tightened significantly. Responding this move, Japanese government has also set the official target to increase production of bioplastics. However, the largest obstacle to achieve the aim has been the fact that a huge amount of fossil fuel is used to dry biomass which is to be material of the bioplastics. As a result, there has been the contradiction that manufacturing bioplastics put large burden on the environment rather than being eco-friendly. Furthermore, the high cost for producing bioplastic has been the reason why the material has not been widespread.
Our RedoxMaster has eliminated this obstacle. By introducing the machine in the drying process, the cost and time to dry organic matters improve dramatically. Moreover, RedoxMaster can avoid oxidization and carbonization of the organic matters, as it does not use high heat. This is advantage because oxidized and carbonized residue causes problems of strength when they are used for bioplastics. The residue treated by RedoxMaster are even and fine particles which are easy to mix with petroleum plastics, although the residue processed by conventional methods such as high heat and centrifugal machines often become dumpling.
Glencal Technology and partner companies make profit by selling the coffee ground residue dried by RedoxMaster to fodder companies and bioplastic companies as materials for livestock fodder and bioplastics.

Case examples (including the cases which are currently being tested)

・Apple pomace, orange pomace, cabbage waste, onion waste, curry waste
・Seafood wastes
・Strained lees of Japanese spirits distilled from sweet potatoes
・Strained lees of Japanese Sake
・Straw mulching of cattle barn
・Coffee grounds, strained lees of green tea
・Wastewater sludge
・Residue of meat dishes (hamburger steak, pork cutlet)
・Pruned wood wastes

Recently, the problems regarding plastics such as low recycling usage of plastic waste and ocean pollution by plastic have been a global issue to solve urgently. As widely reported, the Collins dictionary in the UK choses "the word of the year" every year. The word, "Single use " was chosen as "the word of the year" in 2018. This indicates how single use plastic such as straws, trays and cups have affected the world's environment including oceans and rivers badly in recent years. Responding this trend, more and more corporations such as Starbucks, Kentucky, Hilton hotels and so on have declared they would stop usage of single use plastic.

According to the repot of UNEP in 2018, "Single Use Plastic", the volume of production is the largest in packaging sector, consisting 36% of the total production of plastic products. Japan waste the second largest amount of plastic per capita, following the US. Although it is thought that Japan is an eco-conscious country, the reality is different from the image.

The plastic waste that is not treated domestically in Japan was exported mainly to China and other Asian developing countries, and those countries accepted the plastic as resources. However, at the end of 2017, China decided to ban importing those plastic waste as it pollutes the environment in China. Other Asian nations followed China's move. As a consequence, the plastic waste is being accumulated in developed countries, and how to treat those plastic waste has been becoming an urgent problem in the world.

To recycle the plastic waste may be one of the solutions for this issue. Nonetheless, the cost to recycle the plastic waste costs largely. The basic rule of 3R is that the first step of the 3R, "reduction" cost the least compared to the latter two steps, "reuse" and "recycling". We should reduce the consumption of plastics rather than trying to reuse or recycle the plastics. From this point of view, biomass plastics made from biomass and petroleum products have attracted attention as a better solution for the plastic waste problem, these days.

Biomass plastics are a form of plastics derived from renewable biomass sources such as grass, vegetables and so on mixed with fossil fuel plastics. Corns and sugar canes are common materials of bioplastics, but any kind of organic wastes including coffee grounds and pruning waste can be resources of bioplastics. In Japan, the amount of domestic production of bioplastics was approximately 70,000 tons in 2013. Japanese government declared in its official plan that they aim to increase the production of bioplastics up to 1,970,000 tons by 2030, while decreasing the production of petroleum plastics.

The are some challenges for spreading bioplastics. Firstly, the production cost of bio plastics is expensive. Secondly, a large amount of fossil fuel is consumed to produce bioplastics. Thirdly, strength and heat-resistance of bioplastics are not so good. The first and second disadvantages are related closely. In order to dry biomass to be mixed with petroleum plastics, high heat is necessary, consequently, huge amount of fossil fuel is consumed to generate bioplastics. It means the production cost becomes expensive and the environmental loading becomes significant. However, by treating the biomass by RedoxMaster, these challenges which have been prevented bioplastics from spreading can be solved very easily. RedoxMaster dry organic matters significantly fast at low temperatures, it is possible to reduce the production cost of bioplastics hugely compared to conventional drying technologies. Moreover, it does not oxidize and carbonize organic substances, the problem of strength can be settled.

We hope our new generation technology, RedoxMaster can contribute to address the plastic wastes problem in the world.
