4 Ideas To Save Costs in Bulk Material Container Shipments

Capex investments are difficult to justify in current market conditions for chemical companies and other raw material manufacturers or importers. You might have a great idea that will improve the processes in your company, but you already know that your boss will not grant you the funds necessary. What would your boss say if you present him a solution to save costs in already existing supply chain processes instead of generating new investment expenses?
Here are 4 ideas how you can cut costs in your day-to-day bulk material supply chain operations:

1. Making the most of a container’s payload:
– Optimize the space occupied by material inside a shipping container. Usually containers loaded with FIBCs (or Big Bags) are only 90% full at most.
– Bulk materials with a light density (below 0.7) will not reach the weight limit per container when loaded with FIBCs.
– Modern loading methods with a linerbag let you use 100% of the available space inside a shipping container.
– Getting more material into each container means that you need to ship less containers in the end, saving you handling and shipping costs.

2. Reduce costs for material packaging:
– One 20’ container is loaded with 20-28 FIBCs depending on the bulk material and FIBC measurements. Each FIBC weighs 1.5kg on average, leading to 36kg of packaging material for 24 FIBCs in one container.
– One linerbag for a 20’ container weighs about 16kg, saving more than 50% packaging material.
– Savings can be generated when only one linerbag is needed per container instead of 24 Big Bags.

3. Reduce necessary handling per container:
– Not only will you be able to save money on the packaging itself, but handling all this packaging and the packaged material will become less costly as well.
– Instead of 24 movements with a forklift for each loading and unloading, the linerbag can be installed and dismounted by one person in a matter of minutes.
– Also keep in mind the handling required for each FIBC inside the production facilities.

4. Automate your container loading and unloading processes with rental equipment:
– Our fourth idea is connected to the former one. Automating your processes for container loading and discharging can allow you to reduce the required manpower and handling steps per container.
– Bulk material loadings and discharges are continuous processes that should not require constant handling steps or even observation by your workforce.
– Many companies offer their equipment on a rental basis that allows you to automate existing processes without an initial large Capex investment.

Reducing Plastic Packaging in Bulk Materials Transports

Millions of tons of bulk goods are transported nationally, internationally and even overseas every month. Companies from all industries make use of different modes of transport to receive or send out bulk materials. There are many options available to move materials from A to B. For short-distance road transports silo trucks or rail wagons are a common option. As soon as the material needs to be transported on a ship the common choice is the standardized shipping container.

While road transports in silo trucks or rail wagons can be done mostly without additional packaging, they will generate additional costs for cleaning of the transport medium depending on the bulk good which is transported. This is a different case with shipping containers. Usually the bulk material in a shipping container is transported with additional packaging around it. This is done to protect the container from the bulk material and also protect the bulk material from any moisture or dirt coming from the container.

The packaging used for bulk materials is typically a so called “Big Bag” or FIBC. It comes in various sizes, the most common ones contain 1m³ or 2m³ of volume. These Big Bags are filled with the respective material individually and stored until ready for shipment. Then they will be loaded one by one into the shipping container by an operator with a forklift. The same procedure occurs at the receiving end. An operator with a forklift will take out every Big Bag individually, store them at a designated location und discharge them one by one.

Another option for packaging bulk materials in a shipping container is the “Linerbag” or “Container Liner”. This bag is installed into the container before the material is loaded into it. The Linerbag covers the whole volume of the container and can be secured with different methods to stay in place for the loading procedure. Financial savings are generated by reducing loading and discharging time, simplifying process steps and increasing utilization of loading capacity.

But how does the linerbag reduce plastic packaging for bulk materials? The answer is simply mathematical. Compare a container loaded with 24 individual Big Bags to a container loaded with one Linerbag. The 24 Big Bags “surround” the material on 6 edges 24 times, while the Linerbag surrounds the material only once. One Big Bag weighs approximately 1.5kg, multiplied with 24 this is 36kg of plastic packaging per container. One standard Linerbag on the contrary weighs only 16kg. That is a reduction of plastic packaging by over 50%! If you would use this example for a supply chain with 3,000 containers per year you would end up saving 60,000kg of plastic waste annually.

For the above mentioned reasons many companies are switching to Linerbags. While suppliers of Linerbags can be found quite easily, manufacturers of machinery to load and discharge linerbags are still fighting for visibility in this new niche. WWTec has been supporting the trend towards Linerbags for over 20 years and is specialized in loading and unloading equipment for all kinds of bulk materials. Many Linerbag suppliers recommend WWTec’s solutions as the best in the market, often referencing the Siloadmaxx portfolio which is developed and distributed by WWTec around the world.

Developing ATEX process in record time

When the request from Finland for handling peat pellets came in, WWTec actually already had a full schedule for the entire calendar year. Of course, we still discussed the desired solution in consultation with the customer. Peat pellets were to be conveyed from a storage hall to a reactor 300m away. Normally, this is done via a pneumatic conveying line. However, a standby solution was still needed for downtime and maintenance work. It quickly became clear that we could not build a new machine for the desired process – the time objective as well as the personnel resources were simply too tight. In addition, at that time an extreme backlog in the supply chains led to unprecedented waiting times for standard components.

Many companies would probably have turned down an order here. Our team at WWTec has a special gift for “inventing” solutions out-of-the-box. An employee with a connection to agricultural machinery came up with the idea of using used potato belt wagons to transport the peat pellets from the warehouse to the silo. There, the carts reverse to a hopper with a filter and rotary valve. The conveyors move the material into the hopper and from there it is pneumatically conveyed up into the silo. We produce the required conveying and process air with our own compressors, which are installed in an adjacent 20-foot standard container. Thus, the machine runs self-sufficiently and is independent of maintenance work on the existing conveying stream.

Since the dust from peat pellets is explosive, the whole thing had to be adapted and tested according to the ATEX directive. Here we have an excellent partner in Bureau Veritas, which supports us from development to acceptance on site. With the described equipment from the second-hand market and from the existing WWTec rental park, this machine could be completed in record time during an economically difficult phase. The customer is pleased with a flexible, mobile and above all safe solution for handling peat pellets.
