Among our first four garments to feature Full Transparency - including The Impact Receipt - is The T-Shirt. Not only of symbolic value, it's also our most sold garment, and therefore represents a large share of our impact. While its CO2 impact is lower than the industry average (2-2,5kg), the proof of the pudding isn't in its impact.

ادامه مطلبCarbon Impacts of Steel . Steel is manufactured in two types of factories. Large steel mills typically use basic oxygen furnaces (BOFs), which burns coal or natural gas to melt iron-ore to extract the iron, and then mixes the iron with scraps of iron and steel to make new steel. Most of the inputs to a BOF are mined, raw materials, so the recycled content level for BOFs is …
ادامه مطلبA mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().
ادامه مطلبAs with all large-scale manufacturing processes, the production or iron and steel generates by-products. On average the production of 1 tonne of steel results in 200 kg (EAF) to 400 kg (BF/BOF) of by-products. The main by-products produced during iron and crude steel production are slags (90%), dusts and sludges.
ادامه مطلبMilling in an attrition mill (Fig. 24) is effected by the stirring action of an agitator that has a vertical rotating shaft with horizontal arms. This motion causes a differential movement between the balls and the material being milled, thus providing a substantially higher degree of surface contact than is achieved in tumbler or vibratory mills.. Fig. 24 Attrition ball mill
