Eco-trading = B2B trading + an eco-conscious heart. Eco-traders prefer environmentally friendlier product (or service) alternatives, channels and/or practices under

business-viable conditions. Taking an eco-conscious approach to B2B trading can help reduce pollution on our planet, increase efficiencies in resource utilization, and reap huge and substantial savings for you in the long run.

Offstock is the first eco-trading platform serving the chemical industry.


Whenever we burn chemicals, carbon dioxide is released into the atmosphere. The extra carbon dioxide trapped under the earth’s surface resulted in global warming. While the average global temperature is increasing, on a daily level the climate is changing in an unpredictable ways (from droughts, to hurricanes, and floods). To reduce the risk of even more extreme weather, we can do a part by reducing the amount of chemicals we are disposing/ burning.

The total carbon which we as individuals are responsible for is called our carbon footprint. With molecular formula of the chemical, obtaining the carbon dioxide figures is quite straightforward. Note that carbon on its own is not a greenhouse gas, but often carbon dioxide is shortened to carbon for ease of reference, and this is the case with the carbon account.

A simple method is shown below to calculate the carbon emission for fully combustion case.

Step 1: Determine the value of A, B and C for CxHy by using the following general equation

CxHyNaO + A O2 --B CO2 + C H2O,   where x,y,A,B & C = 1,2,3,.....

Step 2: Calculate the CO emission by using the following formula

(Total Weight of CxHy ÷ Molecular Weight of CxHy) × 44*B

where Molecular Weight of CxHy = (12*x) + (y) + 16(z)

Step 3: Calculate carbon emission by multiply the above CO emission by 0.27

By redistribution, you are able to re-capitalize surplus raw materials, reduce chemical waste, and also be environmental friendly.

Join Go Green! and stack up more savings

Go Green! is an Offstock’s exclusive loyalty program of benefits for buyer. With Go Green!, buyer can enjoy more savings and help to do a part for the environment by reducing industry wastage and carbon dioxide emission.

According to United Nation Statistics Division, more than 92,866,200 tons of chemicals from 48 countries are collected and destroyed in the year 2007 alone. Waste and chemical burning give off carbon dioxide and contribute to the climate change. Hence in Offstock, we hope to minimize chemical waste by redistributing surplus chemical raw materials.


Go Green!

For every 1 kg of carbon emission reduced, you will be entitled to 1 Offstock Carbon Credit (OCC). Offstock Carbon Credit can be used to offset your freight cost.

1 Offstock Carbon Credit (OCC) – USD $0.05

Carbon emission is calculated by us whenever you purchased a carbon containing product from Offstock.

How the calculation is done: 

Example: Burning 1 kg of Macrolex Violet 3R (solvent) emits 0.7 kg of carbon. By purchasing 1000 kg of Macrolex’s solvent, you will be able to reduce 700 kg of carbon emission and are given 700 Offstock Carbon Credit.

700 Offstock Carbon Credit (OCC) = 700 x USD $0.05 = USD $35 to offset your freight cost!

To protect the interests of buyers, Offstock accepts only chemical raw materials that are in usable state (or can be restored to usable state). Many chemical raw materials deteriorate with age, and it is recommended that you list such goods on Offstock once you deemed them as “surplus”. Offstock does not accept goods that has deterioated to the point of uselessness.

Further, Offstock does not accept raw materials that will eventually end up being consumed, inhaled, injected, or applied on human beings and animals. Offstock seeks to prevent harm to living things whether directly or indirectly through the use of its services


Recycling is the generally defined as the process of collecting end-of-life goods and recovering usable components through a destructive process (that is, the goods must be destroyed in order to recover usable components).

In contrast, redistribution deals with surplus, unused goods and seeks to find parties who can use them through a systematic process spanning from sourcing to logistics. Redistribution is non-destructive.
