I/S RENO Nord Aalborg choose ODACON film forming amine technology from REICON for preservation of the back-up boiler. Line 3 of the waste incineration plant is only few times a year in operation for 2 -4 weeks each. To improve the corrosion protection during the standstill periods, RENO Nord decide to inject ODACON in the water steam cycle during the operation to build up the protective amine layer.
Whenever you begin a new romantic relationship, there’s that period of excitement – after all, every first date has the potential to be the last first date of your life, right? Once the honeymoon period ends and reality sets in, you may realize you’ve found the love of your life – or it’s equally likely you’ll start noticing all kinds of serious red flags you didn’t pick up on earlier. Not every relationship you embark on will (or should be) be long-term.
With age (and a boatload of failed relationships) comes experience. In a recent AskReddit thread, Redditors shared how they knew their relationship wasn’t meant to last.

The main problem with anaerobic digestion of crop residues is that most of the agricultural residues are lignocellulosic with low nitrogen content. To improve the digestibility of crop residues, pre-treatment methods like size reduction, electron irradiation, heat treatment, enzymatic action etc are necessary. For optimizing the C/N ratio of agricultural residues, co-digestion with sewage sludge, animal manure or poultry litter is recommended.
Several organic wastes from plants and animals have been exploited for biogas production as reported in the literature. Plant materials include agricultural crops such as sugar cane, cassava, corn etc, agricultural residues like rice straw, cassava rhizome, corn cobs etc, wood and wood residues (saw dust, pulp wastes, and paper mill.
Others include molasses and bagasse from sugar refineries, waste streams such as rice husk from rice mills and residues from palm oil extraction and municipal solid wastes, etc. However, plant materials such as crop residues are more difficult to digest than animal wastes (manures) because of difficulty in achieving hydrolysis of cellulosic and lignocellulosic constituents.
Crop residues can be digested either alone or in co-digestion with other materials, employing either wet or dry processes. In the agricultural sector one possible solution to processing crop biomass is co-digestion together with animal manures, the largest agricultural waste stream. In addition to the production of renewable energy, controlled anaerobic digestion of animal manures reduces emissions of greenhouse gases, nitrogen and odour from manure management, and intensifies the recycling of nutrients within agriculture.
In co-digestion of plant material and manures, manures provide buffering capacity and a wide range of nutrients, while the addition of plant material with high carbon content balances the carbon to nitrogen (C/N) ratio of the feedstock, thereby decreasing the risk of ammonia inhibition.
The gas production per digester volume can be increased by operating the digesters at a higher solids concentration. Batch high solids reactors, characterized by lower investment costs than those of continuously fed processes, but with comparable operational costs, are currently applied in the agricultural sector to a limited extent.
Codigestion offers good opportunity to farmers to treat their own waste together with other organic substrates. As a result, farmers can treat their own residues properly and also generate additional revenues by treating and managing organic waste from other sources and by selling and/or using the products viz heat, electrical power and stabilised biofertiliser.
On turning organic waste into non pollutant and income generating resources
What the First World did to their waste? Turned it into biogas.
Organic Waste to Biogas, Biomethane, or Bio-LNG Resources
We have lots of rotting and stinking organic waste in our country. We can do the same.
