Three companies; Idemitsu Kosan Co Ltd, Ube Industries Ltd and JGC Corporation launched joint workshop to establish new technology to produce carbonate which will be raw material of concrete, from industrial waste and carbon dioxide.  The aim is to utilize carbon dioxide in the air for producing other raw material and to establish carbon dioxide emission reduction system by lower cost. Commercialization is planned by 2030 after fundamental researches.

The established organization is called “CCSU workshop.” In addition to separation and collection of carbon dioxide, utilization is also researched jointly with several universities.

Calcium and magnesium will be extracted from industry waste to produce carbonate by reaction with carbon dioxide. Fundamental research will be planned in 2 years and production process will be followed.

Idemitsu and JGC will also develop CCS, underground storage of carbon dioxide, in their oil refineries in Hokkaido. In this research, cost reduction is expected to be superior than CCS since generated carbonate contributes to profit.

Yamaha YZ450F with enhanced riding performance by new engine and frame.

(Source: Response, June 20, 2019)

Yamaha Motor Co., Ltd will start selling 2020 model 7 types motocrossers “YZ series” on August 20, including YZ450F which equips new engine and frame.

2020 model is minor changed from existing YZ450F.  New engine whose performance enhancement and lightweight are realized at the same time, improves riding performance. Compression ratio enhanced from 12.8:1 to 13.0:1 by newly designed piston and cylinder head and compact design on combustion chamber. Intake port was successfully optimized by changing chelicerae of intake-exhaust valve from 21.5 degrees to 14.5 degrees.  All parts’ specification were reviewed to improve output power.

Cylinder head was compacted and 5mm was shorten between Camshaft and crankshaft, which concentrates mass. Magnesium parts items are increased in head cover, which contributes to save weight by 310.5 gram.

Domestic Magnesium Market - April 2019

(Source: April issue of Import/Export Statistics (customs clearance basis) of METI. Compiled by The Japan Magnesium Association.)


According to Ministry of Finance’s Import/Export Statistics released in April 2019, magnesium metal import was 2,107.4 tons, 22.4% decrease on month-to-month basis (21.7% decrease from the same month previous year).
Magnesium powder was 415.7 tons, 43.0% increase on month-to-month basis (55.0% increase).  Other product was 210.9 tons, 214.7% significant increase on month-to-month basis (14.0% decrease).  The grand total was 2,733.9 tons, 10.4% decrease on month-to-month basis (12.0% decrease).  Up and down between 2,000 ton level and 3,000 ton level has been repeated for every month this year.  Therefore attention must be paid on total import amount.

The metal consisted of 4 categories as follows: (a) 1,731.6 tons of pure magnesium, 22.4% decrease on month-to-month basis (30.1% decrease);  (b) 357.2 tons of die-casting alloy, 22.0% decrease on month-to-month basis (54.1% decrease);  (c) 0.2 ton of high purity magnesium, 80.0% decrease on month-to-month basis (90.0% decrease);  (d) 18.3 tons of casting alloy, 598.7% significant increase on month-to-month basis (48.4% decrease).

As for the average import price of magnesium metal in April, pure magnesium was 287.3 JPY/kg,  3.7 JPY or 1.3% increase on month-to-month basis. For side note, it was 34.9 JPY/kg or 13.8% increase from same month previous year.  Magnesium alloy was 330.8 JPY/kg, 1.0 JPY/kg or 0.3% decrease on month-to-month basis. And 27.3 JPY/kg or 9.0% increase comparing to same month previous year.

As for the total amount of import from January to April 2019, magnesium metal in total was 9,391.4 tons (18.6% increase from same period previous year).  Looking at the breakdown in magnesium metal, pure magnesium metal was 7,778.4 tons (40.2% increase), high purity magnesium metal was 19.2 tons (200.2 % increase).  Die-casting alloys was 1,478.8 tons (28.9% decrease).  Casting alloys was 115.1 tons (25.8% decrease).  Magnesium powder was 1,276.9 tons (3.2% decrease), other products was 790.2 tons (17.1% increase).  As a result, the grand total of import from January to April was 11,458.5 tons, 15.6% increase comparing to same period previous year.


The magnesium export in April consisted of 0 kg of pure magnesium, 0 ton of magnesium alloys.  Magnesium powder was 0.002 tons, 99.9% decrease on month-to-month basis.  Other products was 9.2 tons, 4.4% decrease on month-to-month basis (2,361.4% increase) including 2.9 tons, 6.0 tons, 0.1 tons and 0.2 tons to China, Vietnam, Thailand and Romania respectively.  The grand total export was 9.2 tons, 44.6% decrease on month-to-month basis (2,329.4% increase).

As for the total amount of export from January to April, pure magnesium metal was 0 tons, magnesium alloy metal was 80.7 tons (92.8% increase), magnesium powder was 3.8 tons (146.1% increase) and other products was 25.0 tons (24.7% increase).  The grand total amount of export from January to April 2019 was 109.6 tons (29.5% increase at same period of previous year).
