Pine needle char beehive blocks are the alternate source of energy utilizing the abundantly available perilous pine needle biomass in the Uttarakhand state. The blocks were previously made with traditional method, which becomes obsolete. This research provides a significantly amended modified approach. The traditional approach and modified approach of pine needle char block making were evaluated based on economics, production rate and proximate analysis. The cost of each piece of char:soil block made traditionally was Rs. 8 whereas Rs. 3.20 for modified block. The modified approach has a greater capacity of 24 kg/h than the traditional approach of 7.20 kg/h. The production rate of traditional approach was 12 blocks/h, whereas modified approach has 48 blocks/h production rate. The proximate analysis shows that the modified blocks have low moisture content, ash content and high volatile matter than the traditionally prepared blocks. The calorific values of traditional blocks were in the range of 18–20 MJ/kg whereas 18.7–28.9 MJ/kg for modified blocks. The modified approach to pine needle char beehive blocks production is an advanced technique with enhanced fuel characteristics properties of blocks that will encourage rural development and self-employment in the hilly region of India.

松针炭蜂箱块是在北阿坎德邦利用大量可用的危险松针生物质的替代能源。砌块以前是用传统方法制造的，但过时了。这项研究提供了一种经过重大修改的改进方法。根据经济性，生产率和相关分析方法，对松针炭块制作的传统方法和改进方法进行了评估。传统上制作的每块char：soil块的成本为Rs。8而卢比。修改后的块为3.20。改进的方法比传统方法的7.20 kg / h具有更大的24 kg / h容量。传统方法的生产率为12块/小时，而改进方法的生产率为48块/小时。接近的分析表明，与传统制备的嵌段相比，改性的嵌段具有较低的水分含量，灰分含量和高挥发性物质。传统块的热值在18-20 MJ / kg的范围内，而改良块的热值在18.7-28.9 MJ / kg的范围内。松针炭蜂箱砌块生产的改良方法是一种先进的技术，具有增强的砌块燃料特性，可鼓励印度丘陵地区的农村发展和自谋职业。
