Four times more efficient e-fulfillment with less floorspace thanks to AutoStore®

Nieuwegein, Netherlands

Active Ants provides warehousing services to various webshops in Belgium, the Netherlands and Germany. The Dutch e-fulfilment company stores and packs goods for its customers and handles distribution. This mostly involves small items that require a lot of storage space. Due to their constant growth, Active Ants needed more storage space.

The company built a new warehouse fitted with AutoStore®, a compact storage system for small goods. Not only has AutoStore® optimised their use of available floorspace in the warehouse, it also increased productivity as it delivers goods to operators automatically.


Increasing growth, manual processes and limited space were the drivers for Active Ants to seek for a new compact storage solution. It needed to hold the 22,000 different SKUs from the catalogue – such as DVDs, T-shirts, books or toys – more efficiently than classical small parts warehouses, and wanted to eliminate long walking distances associated with manual picking.


AutoStore® was specially developed for the storage of small goods such as those distributed by Active Ants. The company now works with a system of 57,500 bins arranged in a predefined grid in the warehouse where bins are stacked as closely together as possible to maximise the use of floorspace. This gives up to 75% more storage capacity per square metre.

The AutoStore® robots automatically pick the right bins and take them to the operators. The operators pick the right goods and continue processing the order.

Since AutoStore® was installed, the company has enjoyed a fourfold boost in efficiency over the previous manual system. In addition the company is also working more cost-efficiently, thanks to automatic order picking.


The storage and picking system needed to be compact and ergonomic. The order pickers no longer need to lift the bins or clock up miles going from rack to rack.

Bin stacking also offers other benefits: the products stay clean because they are protected from dust, and the system also helps prevent theft.


  • Automated and cost-efficient system
  • More storage space per sqm
  • Expandable for future growth
  • Safe storage of goods

AutoStore® is attractive in terms of future scalability. The system was originally installed 2016 and as the E-commerce fullfillment company grew the business much quicker then expected, the Autostore systems was massively enlarged in 2018.

The AutoStore® concept is also easy to integrate with other systems. For instance, Active Ants incorporated a packing machine into the logistics process.

The AutoStore® system directly interfaces into Active Ants’ in-house developed ERP system.

The Process

The AutoStore® system for Active Ants features two picking stations, each equipped with six packing stations. A Pick-to-Light system indicates the bin segment where the picker will find an item and the order bin where the item should go.

Once shipments are ready, a smart bin transport system takes them to be weighed and photographed. Some shipments are first taken to another part of the warehouse, where Active Ants add large or bulky items to the shipping parcel manually. AutoStore® handles around 90% of all goods, the rest is picked manually.

The order bins end up at the packing tables, where they are automatically scanned and a monitor displays the packing instructions. The shipping label and the order form are printed for the packer to complete the order. The empty bins go back to the picking stations and the shipments go to Shipping.

For the design of the packing stations, Active Ants collaborated with Dematic to find the most efficient, ergonomic and economical solution. The stations will be easy to expand in the future and during peak loads.

“Dematic is a reliable partner to count on.”
