As well as its involvement in the water management industry Asset International also operates within the renewable energy sector, principally in three main areas: Hydroelectric, Anaerobic Digestion (AD) or biogas and Air Vent Systems.

With growing global energy requirements and an acceptance that fossil fuels and nuclear power are unsustainable and will potentially damage the planet irreversibly, the focus on developing renewable and sustainable energy sources is vitally important.

Weholite HDPE pipes are at the forefront of technological innovation and development. The core competencies within our business, such as production and fabrication, transport, design and installation, give us a strong competitive advantage over traditional materials.

Asset offers a comprehensive design service. This is inclusive of structural calculations in accordance with BS EN 1295–1: 1998, “Structural design of buried pipelines under various conditions of loading.” Asset also offers flotation calculations combined with advanced finite element analysis results, in order to visualise the behaviour of the pipe under buried conditions. Furthermore, Asset offers extensive site and after sales support.

Hydro-electric usage

Hydropower is the most popular renewable energy resource in the world, with a 16% share of global energy output and counting. In recent years, the UK has seen an increase in the number of hydroelectric projects, mainly small power plants that utilise local waterways for the production of clean, cheap energy.

Hydropower projects, where water is diverted from a river or collected from surface runoff and conveyed down a penstock piping system to a generating station, are seen as an environmentally friendly way of generating electricity without adversely affecting flow or water levels.

Over time Weholite has proven to be the ideal choice for project owners, engineers, and contractors because the advantages of using Weholite provide an economical alternative to other piping materials.

Ground Air Heat Exchangers

Ground air heat exchangers offer a sustainable way of heating and cooling buildings utilising the natural temperature of the earth.

Weholite is utilised in Rehau’s  AWADUKT Thermo ground-air heat exchanger system, also known as ‘earth tubes’, for pre-tempering ventilation air. Ventilation air is drawn through underground pipes buried at a depth of 1.5m, which pre-cools the air in the summer and pre-heats it in winter, using the near constant temperature of the ground (7-13°C).

In partnership with Rehau, the system has been extensively used across the UK in commercial and public sector projects, largely in the education sector.

The utilisation of a ground-air heat exchanger is a cost effective method of tempering the air to ensure the building has a low carbon footprint.

AD – Biogas

The UK’s Transmission System Operator, responsible for distributing and generating electricity, recently announced that biogas, a renewable energy, could be responsible for 10% of the nation’s gas output by the year 2020. If targets are met, the National Grid hopes to have 45 new biogas power stations connected to the grid within the next two years.

Biogas is typically produced from the breakdown of organic matter in the absence of oxygen, through a procedure called anaerobic digestion, whereby biodegradable materials, such as manure, sewage and plant material are broken down. This is done in tanks, so that the gas produced can be harvested.

Weholite pipes and tanks are used in biogas projects across the UK. Weholite chambers will house state of the art technology to transform the energy requirements at the plants by converting food waste and animal by-products into power and heat.

Applications include:

  • Ground air heat exchangers
  • Anaerobic digestion vessels
  • Air vents and odour control
  • Geo-thermal chambers
  • Water energy exchangers
  • Wind farm surface water drainage
  • Above and below ground rain water harvesting tanks
  • Hydro-electricity pipelines
