Frequently asked questions
What does
it mean when a container/drum is UN-free?
The abbreviation UN on containers and drums means that the
packaging complies with international standards for the transport of dangerous
goods according to ADR, RID, and IMDG regulations. Specifically, UN
certification indicates that the packaging has been tested and approved for the
safe storage and transport of substances classified as dangerous. If a
container or drum is "UN-free," it means that it is not certified for
the transport of hazardous substances and is intended for other purposes, such
as the storage and transport of non-chemical substances, food, or waste, where
UN certification is not required.
How to winterize a drum?
To winterize a drum, it is necessary to drain it, clean it,
and store it in a dry, frost-free place, or at least protect it from the
elements.
Detailed procedure:
1. Emptying and cleaning:
If the drum is filled with water, drain it. Ideally, wash the drum and let it
dry thoroughly.
2. Protection from frost:
The barrel material can be damaged by frost, so it is important to protect it
from the cold.
3. Storage:
Ideally, store it in a dry, frost-free room such as a basement, garage, or
utility room. If this is not possible, place the barrel in a sheltered area and
protect it from the weather, for example by wrapping it in insulating material.
4. Turn upside down:
It is advisable to turn empty barrels upside down to prevent snow and water
from getting inside.
5. For plastic barrels:
It is particularly important to ensure that plastic barrels are not exposed to
frost and sunlight, which can damage the material.
6. For barrels used for bathing:
If you use a barrel for bathing, it is a good idea to drain the water, clean
the barrel, and store it in a covered area or at least protect it from frost.
Winterizing the barrel will extend its life and prevent damage from frost and
weather conditions.
Which
barrels are suitable for transporting liquids and which are not.
Barrels with a solid lid and plugs are suitable for liquids.
Barrels with removable lids are intended for loose or paste-like substances,
not liquids.

What is the maximum heat
that a PET bottle/bucket and other goods can withstand, and can they be frozen?
The temperature resistance of PET bottles is usually up to
40 °C for long-term contact with food. The optimal temperature for storing PET
bottles is between +5 °C and +25 °C. PET material can be frozen and retains its
mechanical properties down to -40 °C. When freezing PET bottles, do not fill
them to the brim.
Algae formation in containers
Algae in IBC containers, especially above-ground ones, is a
common problem that occurs due to sunlight, which promotes algae growth. To
minimize algae formation, it is advisable to place IBC containers in the shade
or cover them with a dark tarpaulin or other cover.
Protective covers specially designed for IBC containers are also available on
the market to protect them from UV radiation and algae growth.

What related products are
needed for an IBC container
Several related products are required for an IBC container,
depending on its intended use. The basic ones include reducers for connecting
hoses, various types of caps and seals for filling and discharge openings,
stands for placing the container, and, if necessary, pumps for handling
liquids. It is also advisable to consider tarpaulins for protection against UV
radiation and dirt, strainers to catch dirt during filling, and drip trays in
case of liquid leakage.
Basic accessories:
Adapters and fittings: For connecting hoses of various diameters and thread
types.
Caps and seals: For filling and drain openings, often in various sizes and
materials.
Stands and bases: For lifting the container and facilitating handling.
Pumps: For pumping liquids from the container, with the option of automatic
control.
Additional accessories:
Cover sheets: For protection against sunlight and weather conditions.
Screens and filters: For trapping impurities when filling the container.
Catch basins and sumps: For safe storage and handling of hazardous
substances.
Connecting kits: For connecting multiple IBC containers.

What packaging to use
for gasoline/diesel
UN-certified HDPE plastic canisters are suitable for
gasoline and diesel fuel, as they are specially designed for the storage and
transport of fuels. Metal canisters, which are more resistant to damage, can
also be used. It is important that the container is designed for this type of
fuel and is properly sealed.
Recommended containers:
HDPE plastic canisters: these are lightweight, durable, and certified for
the transport of hazardous substances, including gasoline and diesel fuel.
Metal canisters: these are more resistant to mechanical damage, but can be
heavier and more susceptible to corrosion if not properly protected.
Fuel hoses: used for pumping and handling fuel. They should be made of
fuel- and oil-resistant materials.
Important factors when choosing packaging:
UN certification: Ensures that the packaging meets safety standards for the
transport of hazardous substances.
Material: HDPE is preferred for plastics; metal packaging should be
corrosion-resistant.
Sealability: Important for safe storage and to prevent fuel leakage.
Restrictions: According to the Excise Tax Act, a maximum of 20 liters of
fuel may be transported in a canister outside the vehicle's tank without
documentation. Storage of fuel in containers outside the vehicle should comply
with safety regulations and restrictions imposed by local laws.
Compliance with safety regulations: Store fuel in a
well-ventilated area, away from heat sources and fire. Keep fuel containers out
of the reach of children. When handling fuel, use appropriate protective
equipment such as gloves and goggles. When handling fuel, take care to prevent
fuel from leaking into the environment.

What packaging to use for
alcohol
Plastic bottles or polyethylene (PE) canisters, or metal (steel) drums or IBC
containers are most commonly used for technical alcohol. For smaller volumes,
bottles ranging in size from 0.5 liters to 10 liters are suitable, while for
larger quantities, canisters and drums with a volume of 60 liters or more are
used. It is important that the packaging has a high-quality seal to prevent
alcohol from escaping through evaporation.
Plastic packaging: Polyethylene (PE) is a suitable material for storing
alcohol because it is resistant to many chemicals and does not allow vapors to
pass through easily.
Metal packaging: Steel drums are another option,
especially for larger volumes of alcohol. It is important that they are treated
internally against corrosion if they are to come into contact with alcohol for
a long period of time.
IBC containers: These containers are suitable for
large quantities of alcohol and are often made of polyethylene or steel,
depending on the specific type.
Closures and seals: Regardless of the type of
container used, it is essential that it has a high-quality closure and seal to
prevent alcohol leakage. Alcohol tends to evaporate, and leakage can be
dangerous due to its flammability.
Safety: When handling alcohol, it is important to
observe safety precautions. Alcohol is a flammable liquid and should be stored
in well-ventilated areas and away from sources of fire.
What is the difference between HDPE, LDPE, and classic PET bottles?
PE, HDPE, and LDPE are types of polyethylene (PE), a
thermoplastic polymer. PE is the generic name for this material, while HDPE and
LDPE are specific types that differ in density. HDPE (high-density
polyethylene) has a higher density and is stronger, while LDPE (low-density
polyethylene) has a lower density and is more flexible.
PE (polyethylene): This is a basic thermoplastic
polymer used to manufacture many different products.
HDPE (High-density polyethylene):
Density: High, typically ranging from 0.941 to 0.965 g/cm³.
Properties: Strong, rigid, impact and chemical resistant, has good UV
resistance, and is recyclable.
Uses: Milk bottles, canisters, pipes, food packaging, toys, building materials.
Common designation: Microten (as a trade name for film).
LDPE (Low-density polyethylene):
Density: Lower, usually between 0.910 and 0.940 g/cm³.
Properties: Soft, flexible, bendable, has good resistance to water and
chemicals, but is less strong than HDPE.
Uses: Food films, bags, packaging, pipes, insulation.
Common designation: Igelit (as a colloquial name for film).
In short: HDPE is stronger and more rigid, while LDPE is more flexible
and softer. Both are polyethylenes, but they differ in their properties and
therefore in their uses.
Is it possible to use a
refurbished/chemically cleaned container in the garden?
For gardens, we recommend refurbished IBC containers that
have been used for food. Alternatively, the REKO version, which has a new inner
bladder and a used cage. Refurbished containers that have been used for
chemicals are chemically washed and may therefore contain residues of chemicals
that can contaminate water.
