Environmental division

Our Environmental services are the most comprehensive and sustainable in Timor-Leste. Our growing range of services, as well as the ever expanding Circul-R factory attest to our environmental credentials and genuine commitment to build a better Timor-Leste.

But we don’t just look after Timor-Leste. We are also very proud of the processes we’re developing to enable communities all over the world to recycle their own waste on location- not only will these processes drastically reduce waste and the environmental damage, but they will also generate employment opportunities for some of our most vulnerable populations.

How can Caltech help your operation minimise its environmental impact and contribute to a more sustainable future.

Waste management & collection

We provide the most comprehensive and integrated waste management services in Timor-Leste – providing customised onshore and offshore waste management solutions. We are involved in waste collection (liquid and solid) onshore and offshore – servicing the oil and gas sector and others.

We are dedicated to recycling a wide array of products and materials while actively seeking innovative technologies and methodologies to enhance our recycling endeavours. We take great pride in our involvement with the ‘Plastic Solution Alliance,’ a collaborative initiative aimed at fostering a circular economy and eliminating plastics in Timor-Leste.

Our recycling efforts encompass a diverse range of materials including:

  • Paper & cardboard
  • Glass
  • Ferrous & non-ferrous metals
  • Timber & wood products
  • PET bottles & any plastic products
  • E-waste
  • So much more

Recycled products

Caltech environmental embarked on a sustainability journey by wanting to create useful products incorporating the recyclable materials that were being collected at the Material Recovery Centre. This triggered the creation of Circul-R, Timor-Leste’s ONLY recycling manufacturer. Circul-R  processes the raw recyclable materials in the manufacturing of their Landscaping and Board products.

We are also investing in the development of processes that will enable communities in other countries to recycle their own waste on location.

See how Caltech is recycling glass and plastic, using plastic to potentially replace concrete and producing garden pavers from sand and recycled plastic waste
