In Stockholm, the Swedish Bioenergy Association (Svebio) has released details about site visits in conjunction with its 5th Advanced Biofuels Conference to be held on September 17-19, 2019, in Stockholm. The sites include Henriksdal wastewater treatment plant (WTTP), one of the largest biogas production plants in the Nordics, RISE –Research Institutes of Sweden Surface, Process and Formulation (RISE SPF) laboratory and to the heavy-duty vehicle (HDV), bus and engine manufacturer Scania.

The Swedish Bioenergy Association (Svebio) is organizing its 5th Advanced Biofuels Conference that will take place on September 17-19, 2019, in Stockholm. The event aims to provide insights on the latest on renewable transportation fuels, novel technologies and what is going on in biofuels policy and new production. Svebio has now announced the locations for the pre-conference site visits to be held on September 17, in conjunction with the event.
Biomethane at Henriksdal WWTP
Inaugurated back in April 2016, the biogas upgrading plant at Henriksdals wastewater treatment plant (WWTP) has the capacity to produce up to 200 GWh or 20 million Nm3 of biomethane which is used as bio-CNG fuel for around 280 buses in Stockholm City, and for the local gas grid. Sewage sludge from a wastewater treatment plant (WWTP) is used as raw material as well as fats, oils, and grease (FOG) from the food industry and glycerol from biodiesel production.
The raw biogas is upgraded using pressure-swing adsorption (PSA) technology from Viessmann Group subsidiary Schmack Carbotech. Biogas production and upgrading is a cooperation between Stockholm Water and Scandinavian Biogas. Currently, a new large tunnel for sewage water and new water treatment plant are to be started construction with a total cost of EUR 900 million which will increase the plant capacity significantly.
RISE SPF laboratories
A unit within RISE –Research Institutes of Sweden, RISE Surface, Process and Formulation (RISE SPF) focuses on chemical processes and pharmaceutical development, surface technology, and formulation. As a partner with industry and academic research groups RISE conduct projects from idea to proof of concept for commercial application.
RISE SPF’s main business areas are within Life Science, Specialty and Fine Chemicals, Bioeconomy and Surface technology with activities that span from lab-scale R&D to concept testing in pilot scale. This includes flexible laboratories for developing, optimizing and testing of for instance new renewable transport fuel manufacturing processes. In these facilities, miniaturized refinery equipment for developing and optimizing new facile processes for converting lignocellulosic and other feedstocks to renewable transport fuels and chemicals together with industry are used.
Scania powertrains
Södertälje, south of Stockholm is home to engine, truck and bus manufacturer Scania. In addition to front and rear axles and gearboxes, Scania’s production facility in Södertälje is also where its heavy-duty vehicle, marine, and industrial engines are manufactured and fitted to all Scania vehicles produced in Europe.
Along with electrical and hybrid powertrains and engines for conventional biofuels such as biodiesel, HVO, and biomethane, this also includes dedicated engines for renewable fuels such as ED95 – 95 percent ethanol and 5 percent ignition improver.
Scania’s foundry in Södertälje casts cylinder heads for all Scania’s engine types and cylinder blocks for Scania’s 6-cylinder engines. After casting, the engine components are machined and then moved on to the mounting bracket. At the engine mounting in Södertälje, motors are fitted to all Scania vehicles produced in Europe. These include straight 5- and 6-cylinder engines, V8 engines as well as industrial and marine engines.
Svebio points out that spaces are limited and that registration is required for participation in the pre-conference study tour which is also subject to change.
